Titan GPS "Fix" - USE AT YOUR OWN RISK

[gc14]

THIS THREAD IS OUTDATED. aGPS SOLUTIONS NOW EXIST FOR ALMOST ALL CARRIERS.

VERIZON USERS SHOULD USE THIS LINK FOR NEW INSTRUCTIONS:


http://wiki.xda-developers.com/index.php?pagename=VerizonAGPSFix

--------------------------------------------------------------------------

Below is a link to the "fix" we've been working on for the Titan GPS.

We've gotten mixed results with the testing thus far. Some who have NEVER been able to achieve a lock have gotten locks within 30 seconds. Some say they don't see any change.

I must reiterate though that this "fix" is not something that works wonders. It merely helps the current situation. People who have trouble getting an initial fix, people who don't see locks for 5-10 minutes, etc may see improvement with this. Since I've applied it, I've noticed consistent initial locks taking anywhere between 30-60 seconds on Verizon. I'm happy with that for now. If you apply the fix and don't see any improvement, it doesn't necessarily mean that it doesn't work, as others are seeing results. Unfortunately, we've been unable to determine why this happens.

You still have to use the same steps as you normally would for using the GPS. This does not negate the act of priming it or using a launcher. Do everything as you normally would after you apply the fix.

The Titan GPS, though functional, will NEVER be able to function like it does for Sprint customers. Until other carriers provide access to a PDE aGPS server, there will always be hardships for the customers. No amount of hacking, fixing, or upgrading can remedy this.

THIS FIX IS NOT INTENDED FOR SPRINT

THIS FIX WILL PERSIST THROUGH FLASHES OF ROM/RADIO.

USE AT YOUR OWN RISK - I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO YOUR DEVICE

I successfully completed this procedure on Vista64 SP1 without issue.

Now I just need to go outside and see if I get a better fix!

Thanks GC for a great and simple tutorial.

Thanks GC for a great and simple tutorial.

if this is supposed to do what we Sprint users have, then you shouldn't even need to go outside :D. I wish you the best of luck.

[aguas]

im gonna try it on my xv6800 in a few.
backing up right now...

edit: just did it and WOW! on a cold boot, it connected to my exact position wiht 4 sats without even shifting. all in 38 seconds (timed it). by far the fastest ive ever gotten in my house. soft reset and went outside, and got an exact lock in 5 SECONDS! holy christ, gc you are the man.

[760hacker]

GC, I will try this as soon as i get home from work and report results. God I can hardly work waiting to do this.

[scotcha12345]

GC, trying the fix now. I've downloaded all of the required apps.

Just for reference, I'm using:
DCD 3.1.2 ROM w/ Radio 3.39, w/ provider: Verizon

I just tried:
Put the phone in DMR Mode by dialing ##3424 and pressing send, or dialing ##3424# (depends on carrier). ActiveSync will disconnect, and the PC should recognize the phone as an HTC USB Modem and will install the drivers.

Both options, whether ##3424 and hit the green phone button...or ##3424# failed to open DMR mode for me. All I receive are a response by Verizon indicating that The phone number either disconnected, is no longer in service. etc.

I'll look around for another option. (This is similar with trying to access the options by calling to change how often the radio toward is checked for calls...I had to go directly into Windows and click ePST )

[gc14]

Are you using a third party dialer? If so, shit can it.

Also, reinstall the verizon carrier cab.

[scotcha12345]

I used the fix for SPB Pocket Plus that would make the Dialer continually pop up by installing a similar dialer I downloaded. (fixes the problem).

Should I proceed to reinstall the Cab from Verizon, or entirely discontinue the process?

I'm glad I'm not the only one that is not content with the GPS mode...from a cold start, 10 minutes can be average.

[serfboreds]

Thanks for the easy tutorial, went smoothly and I think it is a bit better. Edit: I know it is better, I just connected inside work where I never could connect before.


I notice that using TomTom I always before had No GPS signal for about 10 seconds, then it would say waiting for a valid GPS signal for another 10 seconds to three minutes or so, sometimes not at all until reboot. When I did it after the update it said No GPS for about five seconds and went straight to "lost gps signal 4 seconds ago". The longest it took to connect was 10 seconds after five tries (longest was after pressing the power button while in the program then waking it up...go figure).

Will you be able to integrate these drivers into the new builds for DCD? Or will we need to do this as the drivers are released.

Just out of curiosity, I know these aren't Verizon drivers, what provider are they ripped from? Will this be something that will be possible to update as new drivers are released?

Sorry for all the questions, another solid release guys.

[MrTek]

BTW - Is anyone using HTC GPS on their phones when they applied this fix? Does HTC GPS even have an impact?

[gc14]

I'm glad I'm not the only one that is not content with the GPS mode...from a cold start, 10 minutes can be average.

Whatever dialer or dialer fix you're using is preventing ## codes. You need to go back to the stock dialer you installed from the kitchen, then reinstall the carrier cab. After that, start over. (You don't have to reinstall the wmodem drivers or qpst)

[btonetbone]

Will we need to redo this process after a flash or hard reset, or do changes stick?

Ivan

[etexter]

I performed the fix on my 6900 and it seemed to get locks quicker after a few soft resets. Not sure if it's placebo yet but will let it run for a few days.

I'm also seeing more sats locked. Not sure the why, but I was normally seeing 5-6 at my desk and I'm seeing 8 now.

[Cycomachead]

thanks I may try this when a working PC comes back...
But what exactly does this change on the phone?
Also is it possible that settings from a Sprint phone (PDE and all) could be mirrored into QPST for a Verizon phone?

[MrTek]

I did this fix before I flashed to 3.1.6. After flashing, I connected it to check, and all the boxes are still checked.

So I believe it survives a flash :)

[MrTek]

Great Job guys! GPS is locking on in under 10s now it seems!

[jimnutt]

Doesn't seem to do much for me, the lock isn't any quicker. By, the way, to get into DMR mode without the keycodes look for DM-Router in the windows directory.

[coffey_joshua]

not much luck. still took almost 1.5 minutes. I'm not concerned but I'm going to check it again in a while just too see if i can get a faster lock later on tonight


Thanks for the work and continued support for this community

verizon 6800

[shapiror06]

thanks sooo much gc14 and dcd. you guys are great!

i was the one who started the original thread about this issue, and this fix has helped tremendously! it still took about ~1.5 minutes, but it was a bit cloudy and it was the first lock since upgrading to dcd 3.1.6.

awesome work though! i can't wait till verizon gets some gps servers up and running (i have a friend that works fro verizon and he swears that verizon is releasing their official rom soon, w/ gps enabled so i'd assume their launching some sort of gps server. who knows though, verizon makes lot of promises). we can only hope!

as of now, this fix works just fine for me, so thank you both very much!

[madjokeer]

Wow man this was an excellent fix for the gps.. when i used the HTC GPS tool, it took maybe minute or more to lock with GPSMODE=4, with this fix, it also took about a minute still.. So i changed GPSMODE back to 2 and did a softreset... wow, it locked like in 10 sec.. never before in my house it did that!! one up for this fix!

Rom: no2chem 5067 kitchen
radio: 3.39

[stevefxp]

It seems the fix works for my 6800, as I am now getting SAT locks within a minute using Google Maps as my test. I followed the same priming steps too.

This is inside my home next to a window, where in the past it would take 5-10 minutes to lock.

Steve

[gc14]

Awesome guys...I'm glad it's working out for most people.

I should also note that you only have to do this one time. It will remain through flashes of both rom and radio.

[dcd1182]

oh yeah, you raise a good point. if people still have crappy fix times after this, they should change that key back to its default =2.

90 seconds is about average/working normally for an initial lock in standalone mode.

[gc14]

dcd you able to get on aim...gotta talk to you about a few things...

[j-squared]

I had similar success to surfbored from first page of this thread. Tom Tom is now locking almost instantly - as soon as the No GPS message goes away - almost instant lock. That never happened before.

I'm using Verizon, DCD 3.0.1 - ran through the procedure just as published and everything was ducky.

Thanks again!

[jshaas2]

i feel stupid for asking this and i'm sorry. i just reflashed to DCD 3.1.6 and now can't find my Quick GPS tab. Before i went through the wiki of installing the GPS fix that gc14 has available, i wanted to try GPS on 3.1.6 with Quick GPS as my primer first. I've searched this forum, googled it, etc. and kind find the Quick GPS cab.

Can anyone post that for me, or bettet yet, if any of you like a better gps primer, feel free to let mek now. I know there are several out there and quick gps worked for me when using 3.0.4, and i'm curious to try it with 3.1.6.

thanks guys.

QuickGPS is not a primer. It's a tool that downloads information about the sats to help you acquire a lock faster.

Primers include software such as GPSViewer, BAF's GPS Toggle, and AstroGPSLauncher.

Here's the cab anyway.

[jshaas2]

thanks man. congrats on your celtics by the way. i love the lakers and Kobe, but the Green Machine had his number.

I used quick gps with 3.0.4 and it worked in seconds. do you think i need a primer with the current radio and rom instead? i thought quick gps was a primer, but guess i should have known better.

Yeah man DEFINITELY felt good bringing home #17 considering I was only 4 the last time they won a championship. Last night was total domination lol.

I'd say just do what you'd normally do for GPS...if you're noticing troubles, then use GPSViewer as it's what I use.

[Cycomachead]

Is it possible to do this from a Mac or linux box? Or on the phone itself? My new (replacement) phone should be here soon and the fixed computer isn't back yet...

Total domination is right. I'm tired of the Kobe=MJ talked. Kobe is best player alive, but never another MJ....although i was a huge Bird fan. :)

Do you use the Holux version of the GPSViewer? If so, i may try that.

[gc14]

Haha I wouldn't say best player alive... Paul Pierce is definitely up there with him, only difference is that Kobe has had great support in his teammates to let him achieve success. Now that Pierce has Garnett and Allen, it's a whole different story. ;)

Yes, I use Holux GPSViewer.

P.S. Who wasn't a huge Bird fan? haha

[kashabrown]

Excellent fix - followed your instructions and 15 secs later had satellites..

Congrats (grrrrrrrrrr) on the Celtics (Knick fan here) - they played the best and deserved it!

[jshaas2]

gc14 i'll have to use your new fix. the Holux Viewer would see maybe 1-2 satellites in the "N" area, but never see anything else, and never lock on anything. i let it run 10-15 minutes. I'll try to this new fix and go from there.

thanks for your help so far.

[gc14]

No has to be PC running Windows

Did you read the prerequisites prior to the instructions?

[crwinger]

quick question, for what reason can we not use this for sprint, along with your prior post with the "instant GPS fix for sprint?"

[dcd1182]

quick question, for what reason can we not use this for sprint, along with your prior post with the "instant GPS fix for sprint?"

sprint already sets everything you need using the PRI. this procedure can only do harm for sprint users.

[kflipproductions]

Did you read the prerequisites prior to the instructions?

nope =p...my sorry

[gc14]

quick question, for what reason can we not use this for sprint, along with your prior post with the "instant GPS fix for sprint?"

Uhh it's not needed for Sprint. Hence why there are two separate threads...one for Sprint..and one for all other carriers.

[serfboreds]

GC,

This fix stays on through Radio and ROM flashes, right?

Why would GPS=4 not work anymore (per DCD)? That seems odd to remove cellphone assistance in locking.

[dcd1182]

my understanding is that it should have never worked. i have no explanation for people's results changing that key in the past. gpsmode=4 uses a method that's not available to you.

You're absolutely right. I've also said the same exact thing in numerous posts in numerous threads about gps.

And does the fix stay through Radio and ROM flashes???

[maccaberry]

gc,

I am down in Australia at the moment (no CDMA) and since I got here 3 days ago I cannot get a fix at all, whereas back in USA I got a fix within a minute in most cases outdoors.

I thought I would give this a try to see if it could help my fix. But no dice. Still get around 6-8 satellites showing up in GPS Viewer but it will never fix. I have the latest (7 days 0 hours) data from Quick gps.

I know that the gps will have been a bit freaked out by the sudden 10,000 mile shift in location, so have left it on for up to 45 minutes in clear view of the sky to try to get a fix but still nothing.

My (external) mini freedom gps got a lock within a minute or so of turning it on.

I am not sure if I will ever get a fix while I am here in Australia, but I will let you know how my fix performance is enhanced by the hack when I get back to US.

[gc14]

Your signature says you're running 3.0.4...are you still?

try and re-run the sprint PRI. i've seen users at ppcgeeks claim their GPS goes out and they have to run it again.

[maccaberry]

Your signature says you're running 3.0.4...are you still?

Affirmative. I know that you had 3.1.6 as a prerequisite but since I saw someone comment that the hack persists after a flash I might try it before biting the bullet and flashing 3.1.6.

I assume I was mistaken and it will not assist 3.0.4??

I will have some time later today to flash 3.1.6 so I might have a go.

Yeah don't use the Sprint PRI...I think dcd thought this thread was the Sprint Instant GPS thread.

Flash 3.1.6, install carrier cab, and try again.

Also, are you using GPSMode=4 in registry? If so, change it to 2......4 is no good.

P.S. When you use GPSViewer, do you click Cold Start after opening the GPS?

[maccaberry]

Yeah don't use the Sprint PRI...I think dcd thought this thread was the Sprint Instant GPS thread.

Flash 3.1.6, install carrier cab, and try again.

Also, when you use GPS Viewer, after Opening the GPS, do you select Cold Start?

You know thats a good question. I have tried hot, warm and cold start and I cant say I have ever seen much difference. I did however use cold start here in Australia a couple of times to make sure the gps new that we had traveled a long way and not to use previous data.

I'll flash 3.1.6 and let you know how I go.

You guys are fantastic. Not only making all this wonderful stuff work for us, but you answer questions in short order.
Appreciate the guidance.

[gc14]

I edited my post with a more important question...perhaps you were already responding before I was finished.

I am set to 2. I did try 4 a while back but I found it was of no help - actually made things worse I think.

Interesting thing though, I have found that if I dont have the Phone radio turned on (no need to sice there is no CDMA here) i cannot get TomTom to connect to either the internal or external BT gps device. I have to turn on the radio, connect TomTom to the gps and then I can turn off the radio again. So somehow the radio does effect TomToms ability to see any (internal or external) gps. But I guess this is off topic and should be in the TalynOne gps thread.

[EinsteinTaylor]

Working great here!!

I've decided that GPS Viewer is garbage as a primer however...When I first started testing, GPSViewer was still taking quite a bit of time to get a lock...then I discovered if I did an "Open GPS", then a Close, and then an Open again, I had an instant lock...

I then started testing with Google Maps, and Live search and was getting nearly instant locks.

I would like to find a primer that works similar to GPSViewer in showing each satellite and strength, but without the goofy issues...

Thanks for all the hard work

i had some issues and removed quick GPS and it worked well maybe you could try that? i don't see how that could be connected but it fixed me not having any birds being seen

[nickles96]

Nice. easy to follow tutorial.. thanks very much for this.
while i didn't notice any increase in lock time (still takes approx 30 secs to a minute), the amount of sats literally has DOUBLED.. i am now locked full on with 8, sometimes even NINE sats..
this has been a great little upgrade..
below find shots from Holus GPS Viewer, ChartCross GPSTest, and HTS GPS Tool.

thanks again for a great post!

That is exactly what the fix is supposed to do. In my first post I said this wasn't a miracle fix and you wouldn't get instant initial locks. In fact, I said that I get initial locks between 30-60 seconds on Verizon. It's supposed to make it consistent and lock more satellites and that's what it seems like it's doing for you.

[viper8u2]

ok, I know I did things somewhat backward here

I loaded 3.1.6 yesterday on my 3.35 radio and liked the rom and things seemed fine. My gps however did not seem to be working that great. I use to get a lock in about 45 seconds before but with the new rom it would not connect.

I tried this fix and it didnt seem to do anything. I reread the instructions and saw that the 3.39 radio was required, doh!

anyways, copied all my stuff off my 2gb card, reformated to fat32 and copied the radio. did a soft reset and #228 and just tried again and got a lock in 10 seconds. Now I tried multiple times before with the 3.35 radio and had it was consistent.

I will continue testing but so far am pleased

Nice work

Sweet deal. Are you noticing an increase in sats?

[viper8u2]

Sweet deal. Are you noticing an increase in sats?

to be honest I have visualgpsce installed and in my house I only show 4, I remember seeing up to 7 before

I will check tomorrow outside and try again with locking on. for me to do this accurately, should I reboot each time to do a fresh initial lock?

No..just wait until you haven't used it for a while. You are seeing increase in your initial lock time though correct?

Firstly, why aren't you out drinking like the REST of entire Boston ??
and second, perhaps update your Wiki pre-req. , as I am running radio 3.35.04, and this was quite a success !

[viper8u2]

No..just wait until you haven't used it for a while. You are seeing increase in your initial lock time though correct?

Just tried again, when trying to lock it would show up to 9 sats, took a little bit longer this time about 30 seconds but locked on 5 right now

Some of us do work day jobs you know....going out drinking during the week then being up for work at 6am isn't my idea of a good time. Trust me, I did my share of celebrating last night.

The prerequisites are there for a reason and will not be updated. This fix works best with radio 3.39.10. It's possible you're noticing improvements with the old radio, though probably not as much if you were using the new one.

just kidding with you

[littlerichie29]

Running 2.49.NO2.5066 with radio 3.35.04 on a bell 6800 running on the MTS network in Manitoba. When i applied this fix, i connected faster, but i would have to soft reset the phone before i could make or receive a call,

Every time i would try to dial, it would say the number is not valid, or the network is unavailable, please try again.

I made sure to disable the data after i shut down the gps app, and i even tried to turn on airplane mode, and then back on with no success.

I undid the changes, and all is well now.

[BillyB0y]

My father brought to my attention yesterday that he got a gps fix around a minute and a half. This was last night about 10:30PM EST. We both have Verizon and are using radio 3.39.10 and dcd's 3.1.2. I tried mine out as well and also got a fix in my house (which was a rare occasion prior to) in about two minutes. We've made no changes to anything involving the gps.

The past week or so when I'd try for a fix it'd take anywhere from 5 to 10 minutes or more outside with no cloud cover in the middle of my work parking lot. Now I have fix times of around 38 seconds after I do a soft reset and around 10 seconds after the first fix.

Times are nearly identical between Windows Live Search and Google Maps.

So I'm not sure if the "fix" for the Verizon gps issue is a placebo now due to whatever randomness has happened between last week and now or if it is actually providing quicker fixes. I have not applied gc's "fix" so I'm not sure what is causing the quicker response.

Apologies for not reading the previous pages and about what the "fix" was supposed to do. In terms of satellites I'm still only getting between 4-6 which works for me. Apologies once again.

[mykleh35]

how do I verify if I'm on gpsmode 2 or 4?? when I go in with regedit to HKLM/Software/HTC/SUPLAGPS/GPSMode I have a value of 0x--2 is that what the value 2 you are referring to?

[gc14]

It's not placebo. It's been verified by many people who have never even been able to get locks before.

[mykleh35]

well I finished the upgrade and didn't see any faster lock or more satilietes... oh well... but is distressing is it shows my location 268 feet north of where I am in Garmin, Google maps and Live Search... Any ideas? soft reboot? go back to old phone QPST version?? any help would be appreciated...

[mykleh35]

a couple soft resets later and I am where I think I am....

[aguas]

should aGPS be enabled or disabled in the registry? i think mine was enabled by default, so ill disable it after i flash and see what happens.

[Cycomachead]

Hmm....I can't tell how much it's helping, but then I probably need to get outside. (After spending yesterday loading up XP on an old box just to try this and flash the replacement.)

GC what's your job and how did you figure this out?

[Cycomachead]

Also what else does this do? It seemed to me like service programming was a sort-of extended epst computer based editor.

[Keystone]

If people are stuck with a dialer without the expected keyprogram codes, then to enter the DRM mode you don't have to reflash to a different ROM or switch dialers.

GC, I just added to the Wiki page that we can directly enter the DRM mode by directly executing ..\Windows\DMRouter.exe /DIAG

Similar for entering EPST with ..\Windows\EPST.exe ##778

Easy to just create a properly configured link to such functions.

This evening I'll try the QPST editing on my dad's phone that has had consistently horrible GPS performance....

[gc14]

No, leave everything as it is. The only thing that should be changed in the registry is GPSMode, and it should be set to 2 (only if you've set it to 4). Nothing else should be changed.

As I've said numerous times...this is not a miracle fix. So far, it seems the majority of people (including myself) have seen a vast improvement. This fix is not going to magically enable you to receive locks indoors (though it could help). It is meant to improve initial lock times and help increase the number of sats.

QPST is not an "extended EPST computer based editor". It is the suite of programming tools used by Qualcomm to interact directly with the MSM7500 chip. It is not meant for end users and I highly recommend for people NOT to play around with it.

Oh, and I'm a Computer Engineer and I specialize in Embedded Systems Design.

GC, I just added to the Wiki page that we can directly enter the DRM mode by directly executing ..\Windows\DMRouter.exe /DIAG

Thanks key, I've also edited it again (for cosmetic reasons lol). I still think the problems people are having with phone codes is a result of bad carrier cab install, no carrier cab install, or alteration of dialer. I've never had an issue with phone codes or dialers on any rom I've used.

[Cycomachead]

Yeah I know...it's just after sitting in a window (where I can usually get a lock) for a few minutes I haven't gotten a strong signal.

Also does Hot Warm or Cold start make a difference? And in GPSViewer do the WAAS and Power Save check boxes make a difference? I use a cold start and leave them unchecked.

[gc14]

The names say it all. If you haven't used it in a while use cold start. I really never used hot start because once you get the initial lock, there is no need to prime it again that quickly. I sometimes used warm start. WAAS is moot because gpsOne doesn't support it, and the Power Save is used when you don't want it going to sleep.

Thanks for the workaround Keystone.

When Google Maps is telling you you're in North Carolina, what does it say in the top right corner where it usually says GPS Active etc. Tell me verbatim.

[scotcha12345]

Reflashed with the Kitchen. Everythings cool....applying the fix now.

[gc14]

Reflash the rom, install the carrier cab, and don't install any third party dialers. Then try.

[scotcha12345]

Got it going now. I'm sure I installed things that were just blowing it up. Thanks again.

[Keystone]

GC, I applied the reset to the GPSOne options on my dad's, and it did make a difference. Same as mine, within a minute down to a few seconds he'll now get a sustained lock. Unfortunately the reception maxes out at 5 satellites and a lock is rarely maintained above 2 or 3. Compared to mine, it's also more prone to losing locks with interference.

So this definitely works to improve reception and locks! But, sadly, not all Titans are equal with some cruising along with 10 satellites seen, with many consistently locked, but now with this fix others may now improve from nothing to being lucky to get half of that and at least achieve sporadic locks upon one's position.

[aguas]

ive been periodically running GPS on my phone since doing this fix, and have found its effectiveness decreases over time. turning off aGPS helps, but it actually takes longer by about 30-60 seconds to get a lock, and even then, it wont connect to any more 6 sats, then drops to 3. i used to get 9 in the same position. ill see what happens with some reg changes and whatnot.

[parcou]

Just want to say thx for the fix as well...my connection sways but over all it is better and reading this thread has taught me a lot!

I am curious since I am new to this. Does signal strength have an affect on the GPS lock. At home i get no bars and one if I am lucky. I am not sure if GPS radio and radio that hit the cell towers are one in the same or dual independently functions? I do better on GPS connects away from the house...

[gc14]

I think I've said it about 5 times now....

Do not change ANYTHING in the registry unless it's changing from GPSMode 4 to 2.

[stevefxp]

I would assume that when we re-flash the phone we would have to re-install this fix correct?

Just a bit of a curious question here about QPST: Can I use it to back up my phone's A-key (along with everything else) and after a radio flash (when there is one) restore the config to my phone to not need to call verizon?

I went outside and got 5 pretty good sat. locks. Better than before I think. Thanks again for this and your other contributions and for answering my many questions.

No for two reasons.

1. I'm URGING people who have limited knowledge about the programming of the qualcomm chipset to NOT use QPST for any reason besides this fix. It's very easy to hose your phone BEYOND being fixable on these forums.

2. The A-key is not stored anywhere because it's a temporary value that is generated differently each time. It's not a value setting such as your MDN, MSID, etc. It's used ONE time to authenticate your phone to the network, and then once authenticated, sets a flag in the system, and then discarded.

[Cycomachead]

Alright thanks.

[serfboreds]

GC,

Out of curiosity to the process. How would one rollback to the previous drivers and settings? For the sake of nerdiness could you explain?

[gc14]

Well...not sure why you'd want to do that...but you have to load up QPST Service Programming again. Click Load from file and select the backup you made during the tutorial. Then...Write to Phone, close, and soft reset.

[serfboreds]

Good to know. Nice to know I can be sure I can make a decision based on a solid comparison.

[Cycomachead]

Yeah I did that testing the differences. I think I picked up some more sats, but it's hard to tell.

One thing to remember: I first backed-up my phone (this is a replacement) before I did the *228 thing. Then when reversed it (after *228) I needed to redo the programming. Makes sense when you think about it. There shouldn't be any problems if your phone was already activated.

[gc14]

lol are you people still thinking this fix does nothing? come on now....

[Osteo]

lol are you people still thinking this fix does nothing? come on now....


I can verify it does something. Sitting on my couch, where I could NEVER get a lock, it gets one in about 30 seconds. Verified before and after the fix. This is the only place in my house I couldnt get a lock and now I can do so consistantly. I'm running n2c 5067 kitchen with the 3.39.10 radio. Out in the open it seems to give me higher signal bars for the sats I do lock on and possibly speeds up the lock by about 15 seconds (from the 30-90 I was taking before).

edit: Oh, I'm using GPSTest to make the comparisons. I do use the HTC QuickGPS to d/l the sat data and have done the reg edit required for it to work.

[gc14]

Any of you ever use the HTC GPS Tool? I came across it recently and it proved my theory I had from way back when the GPS roms first came out that there IS indeed a cache on the gpsOne chip. It functions the exact same way as Holux GPS Viewer except it has more debug and dev features AND it has four starts as opposed to GPS Viewer's three (Hot, Warm, Cold). Can you guess what the fourth one is? It's "Clear Memory". I'll never go back to GPS Viewer. When I prime my GPS with HTC GPS Tool, I always use Clear Memory, which I believe (not having done any real research) functions the exact same way as Cold Start, but clears the cache first.

I have used that program for a while but it does not have the four startup modes. I do think it has a bit more information between it's "panel" and "stats" screen than does, but I don't use that stuff much. As a primer, HTC tool seems a better cold primer than any I've used with TomTom. I have been getting instant connections. Even if it is a sugar pill, it sure tastes sweeter.

QUESTION: Is it possible to create new cab so that it starts on Baud 4800. Mine seems to reset to max baud. Does that affect lock in this program?

I use it sometimes, but I find GPS Viewer is faster for priming. My version has a 5th setting "Xtra Start" but when I try to use it I get a message saying it's only supported by qualcomm, which doesn't make sense.

Also wouldn't a cache of recent locks/locations help you get a lock faster or what's the reason for clearing the cache?

I'm going to try the (I think) new version provided by serfboreds.

[gc14]

In my experiences with this chipset, when you initialize the GPS, instead of trying to lock immediately, it instead brings you to the cached location and THEN attempts to lock.

And nickles, first off, it's developed by HTC for this chipset. Second, as I said, it clears the cache, GPS Viewer does not. Third, it has more features pertaining to the gpsOne chipset.

[Cycomachead]

Holy crap, I don't know what I did differently than a few days ago, but now I'm getting 7-9 sat locks in my room! :D And it's a bit faster too.

However, there is a downside to the HTC Tool: It won't stay open in the background, at least not for me. It doesn't really matter because once the GPS is primed it works w/o the priming app, but I find it interesting to watch the satellites. Also GPS viewer had refresh issues where it wouldn't report a lock unless you switched apps and switched back.

Now if only I could change the default baud rate....will be back.

[parcou]

GC or anyone...newbie question...

Performed the update and as you stated 50/50 for some Verizon issue I know. However if I am stating it right, I believe I read that the fix really tones in on collection more satellite connections than locking in 5-30 sec. which most want.

If I got that right, for ones like me who do connect over a longer period of time would using Quick GPS be a negative to this fix? So what I am asking if I installed Quick GPS is this safe?

Its probably your dialer. You need a dialer that will allow the ## codes so you'll most likely have to go back to stock dialer.

Here are my results so far.

The test system is a Verizon xv6800 running 3.04 DCD and radio 3.35.04. As noted in the original post this does not match the requisites, however I love to tweak and gave it a go :)


The test program was Windows Live Search.


I got mixed results. Before I had never seen the cache effect some people talked about, however after this update I definitely could see this in action.

Here was my test procedure.

1 - Obtain lock at my house through the skylight. This took 3 minuted and got more satellites than I normally get'

2 - Go to bed. Had dreams that the tree outside got hit by lightning.

3 - Drive to the bottom of the hill the next morning. 1/2 mile, very curvy and hilly.

4 - Obtain lock while driving from bottom of hill to work. Took 5 minutes while moving at my Hyundai blistering speed of 45. This is normal for pre-change testing. What was different was that it instantly locked on my house, where I was the previous night. The arrow was red, so WLS thought I had a GPS lock. Normally it will stay grey until I get a lock.

Once locked I had more satellites then normal.

It is helping, but as stated it is not a miracle cure.


I have a technical question. What is preventing the use of Sprint, or Quest aGps servers on a Verizon phone? Is the IP blocked outside of the network or is there something deeper causing the issue?

i think it has something to do with the towers, since when ur on verizon ur not using a sprint tower, the ip ur using doesnt get you any information from the tower.

needs to be a sprint phone connected to a sprint tower for it to work.

Seriously...if you aren't going to follow the instructions and abide by the prerequisites, then don't even bother posting your results as they are irrelevant.

In order to conduct an experiment all other factors must be held constant with 1 variable.

Quite frankly, I don't care what results you are getting with 3.0.4 or the old radios because that's not what is being tested.

If you don't want to take my word for it that 3.1.6 and 3.39.10 is the best combination at the moment fine...to each his own.

But it's useless to apply this fix and post results based on any other combination.

it certianly IS very relevant that people test with different scenarios.. thats what testing is all about.

If' it did not work we always have the OEM rom so no one forced this on us :-)

I can say that this has increased the amount of satellites I get from my apartment window. Before I could never get a lock (now I get 4 sats), and the only way I could get a lock before was from the dashboard of my moving car which took about 2 minutes.
Also, after reading through all 15 pages of this thread :eek:, the HTC-GPS app works much better for me than GPSviewer.

Oh and this was from a fresh rom update to DCD 3.1.6, and already had 3.39 radio. I had to do a few soft-reboots and a single memory cache clear of the GPS receiver.
Thx GC & DCD for all the hard work!

does anyone else see the htc gps tool slow down their device? when i run the app it is usually slow to respond, and then if its running in the background, its almost almost impossible to run anything else on the device.

anyone seen this?

It's not meant to run in the background. You fire it up, let it lock, then close it. Then you launch your GPS software of choice.

OK!!!! that is what I am doing wrong....yes it does slow my device down due to me running it in the bg...I did not know. Now I am still trying to figure this out and a good member here pm me stating to set the com, speed, (clear, cold, hot, etc.) option I forget right now then the open button...what I was not doing since I did not know was to hit Nav afterwards.

Now you are saying wait until lock...I assume lock is not when the satellites are red...???..??? not certain what locked would look like in the app...?

Com4/baud rate 4800/Clear Memory

Click Open, then click Nav. Init. It's locked when the bars turn from red to green in the Satellite tab.

P.S. In the Satellite tab it tells you what Mode you are using (GPSMode). For all you people who don't believe me that it does nothing, go ahead and try to set GPSMode=4 in the registry, and see what it says it's using after....

[rhannahs19]

i have been reading in this thread that after the edit to the phone, people are getting better results using gpsmode 2. however, i am seeing in older posts like over on ppcgeeks that people are saying that using mode 4 works better.


so if i am correct it appears that mode 2 is better to use after these edits have been made? mine was already set to gps mode 2 with no2chems rom and i didnt have any luck connecting to sats, however ive only gotten a connection once and that was awhile ago. so i changed my gps mod to 4 now and im testing it out, dont seem to be having much luck. i am using htc gps tool com4 4800 baud rate, open gps, then clear memory and int gps. do you guys have any suggestions to get my gps workin? should i change back to mode 2?

one more thing:

i did set registry to mode 4, soft rest and htc gps still says mode 2... WHAT DO I NEED TO DO ARGH!!!! Thanks

[gc14]

Ok....EVERYONE needs to go check the first post again as I have made an update to it.

[rhannahs19]

sorry i was reading so much information here and there. Even with GPS MODE 2 i do not have very good results, I'll see two or three sats at a time, but will never connect to them. any ideas? thanks

[gbenj]

GC, sorry if im saying something u wanted secret, but seeing as its in your sig, you cant be trying too hard to hide it.

what in the heck is radio 3.42.02, and where can i get it?

is it stable? wheres it from? better gps, cmon, post about it on the forum, before bragging in your sig about it.

Since 3.42.02 is NEWER firmware, I have changed the prerequisites to either 3.39.10 or 3.42.02. As always, I recommend using the LATEST firmware on your device. If you would like to discuss results using 3.42.02 and/or 3.2.0 then by all means go for it.

[Armadous]

I want to thank you so much for this. I flashed my damn phone 5 times thinking I was doing something wrong. Turns out I did it right from flash one and I was simply not waiting long enough to get a fix.

With GPS viewer I was finally able to figure out what was going on and the fix got me a position in about 3 or 4 minutes. I was so excited it finally worked I ran down the street to watch the google map dot follow me. It was very exciting. :P

[the 0ne]

Hello,

I searched through every page of this thread with no luck. Is this fix compatible with radio 3.42.30? The Wiki entry says to use radio 3.39.10 or 3.42.02

I'm currently on Verizon running DCD 3.1.6 and radio 3.42.30. Not sure if it *should* make much of a difference applying this fix.

[auto3251]

my 7500 is under com5

does that mean i should use com5 on all my gps programs to get quicker/better locks instead of 4?

[kflipproductions]

my first 6800 used COM 5 instead of 4. Try it out i'm sure it'll work better.

[xx173xx]

OK.... I am freaking out. Can someone help me? I have installed my bootloader, rom, radio, and everything. I have been working on putting some stuff on my Titan like SPB Mobile Shell and others while trying to get my GPS working. I have downloaded the HTC GPS Tool, quick gps to help (recommended by a friend) and have both TomTom v6.75 and google maps. I have been trying to get a fix on some satelites using the GPS Tool but at first it wouldn't find anything. I even went walking around in the Arizona sun for a while to get a fix. Anyways, I didn't get anything and now when I try to run the GPS tool it gives me the "Failed to send NMEA command.." message when I try to 'open' the connection. I have everything set to the correct settings...4800...com4... automatically connect... all of the stuff here that was stated. I have even tried reinstalling the program. Any ideas???

[WannaBeSedated]

Ok, I have read every post here before posting this. I have QPST installed. ## codes don't work, so I finally got PocketCMD working and ran DMrouter.exe /diag. Looks like everything is going to work. I go to add the two (2) ports per the instructions, but I only see COM3. There isn't anything else listed. Looking at the device, DMR is running. I closed QPST & DMR and ActiveSync starts back up.

Any advice here? I don't understand why I am not seeing what I should. It doesn't look like the drivers are getting loaded, so I feel like I am missing something.

Thanks! Cheers...

i assumed you made sure under phone settings, you have location setting set to location on instead of e911, seems mundane, but ive forgotten to make sure its on after flashes etc..

yea, I made sure that was selected and not the 911 radio button. Any ideas?

http://wiki.xda-developers.com/index.php?pagename=TitanGpsFix

The QPST program was showing that my COM 1 was "waiting" and not enabled. Any idea what the cause of that was? I went ahead anyways with the fix and it was a great success.

Great job once again

Wow!

Went from 30 seconds or more (sometimes lots more) to around 4 seconds

It occurs to me that it might be possible to get the necessary settings for tower assistance from a phone that supports VZ-Navigator? In particular the ip address of the server? Someone with QPST and an appropriate phone might be able to locate those settings? (I have an appropriate phone available but no cable to connect it to a computer). Just kind of speculating out loud...

[verizonguy]

For those who have custom dialers and can't use ## codes, here's a little secret for ya:

Go to the today screen. Hold down the select button on the front of your phone. While holding down the select button, press and hold the stylus to the small time at the top of the screen. Continue holding the stylus to the time, and release the select button. A small menu will pop up with a Run option.
Select Run with the stylus, then in the run box type
/windows/dmrouter.exe DIAG

This will allow you to get into your diag menu.

[verizonguy]

Thanks for this GPS fix.

My Setup:
Carrier: vzw
Radio: 3.42.30
Rom: wm 6.1 aku 1.04 from no2chem's 5067 base.

My Results:

gps lock time before fix: 30-45 seconds.
gps lock time after fix: 3-10 seconds.

Only side effect I've found is after upgrading to the 3.42.30 radio, I was able to get 1-4 satelites inside my house (made of brick), but after applying this fix, I no longer get signal in my home. This is obviously a good trade-off though as I dont need gps assistance in my home. :P

[c@rL0$]

Will this work on radio 3.35? Or a ROM below 3.1.0?

[gbenj]

has anyone whos seen results with this fix, or anyone with verizon seen good gps in NYC?

I'm starting to think i might be the only one here in the city, and im trying to see if my problems are specific to being surrounded by buildings all the time.

I will most likely forget this in 10 minutes, but what a great little trick. I spent hours tracking down PCMD and then trying to get it working. Sheesh! Now if I could just figure out why I don't get a COM4 showing up in QPST I could soon become a happy camper.

By the way, what was I thanking you for. J/K :D

[dbrown2]

I am on VZW, but not in NYC. So I am not sure this helps or not.

I am on 3.2 rom and 3.42 radio in Columbia, SC. My GPS setup would take between 1 to 3 min.

Now I am getting locks less then 30 sec every time.

Thank very much for this trick... Would love to understand what it did, but I don't know if I could.

[Magicality]

This "fix" worked great for me.

Note: The QPST version provided in the first post was released BEFORE the MSM7500 was introduced!! It's an old version, but should still work as described. However, I recommend you download a newer version, such as built 264 which can be found here:

[mdjkim]

Does anyone know if the GPS will still work if you apply this "titan GPS fix" and then disable your phone service?

Currently, without the fix, the GPS still works - even if I disable my phone service. So, I know that this unit can work as a standalone GPS navigator. I'm just wondering if the same will be true if I apply this fix. Thanks.

HELP!!!

my ## codes werent working either, so i got into DMR through the Virtual Dos on Pocket Controller pro. even though the phone went into dmr and deactivated from active sync, i still had to unplug it from the usb then plug it back in in order for the computer to recognize it as the modem drivers.

1) install modem drivers
2) install QPST
3) connect w/ active sync
4) enable dmr (active sync should disconnect)
5) unplug usb from comp
6) plug it back in
7) run QPST and add ports

you'll have to run the dmr command again when youre done to disable it, or just soft reset.

that should work. try it

Thanks! I actually got it working last night, so I was pretty stoked that your directions above are pretty much what I did.

Now, I activated the backup of the phone (Save to File) at which point the "Service Programming" window disappeared.

A) How long should it take to save?
B) Will the Service Programming window come back when it is done?
C) Every time I try to open Service Programming it says something else
has a lock on the phone.

I finally just killed the process as there is no way it could have taken this long. When I went to edit the gpsOne tab, none of the items were greyed out as the instructions state. So, I went ahead and unchecked and re-checked them, and than wrote to the phone. Went outside to try it out, no change. I sometimes get lock in 30-60 seconds, if I am lucky. Otherwise, I get no lock at all without popping the battery.

Is there anything that I could have missed? Does this sound like I missed a step? I did update my radio to 3.42.30 in between all this, but from the comments I read it shouldn't be worse because of the change. Quite frankly, it seems like it is exactly the same way it was before doing the QPST steps.

Help! I am so close to my perfect device. I just wanna get the stupid GPS working and I am done!

Thanks for everyone who has helped already and those who might help in the future! Cheers...

Thanks again! Cheers...

i'm not really clear based on the information you gave, but killing the process could have not applied the fix to your phone. put your phone back in DMR and open the port in QPST. read from the phone, and check the gpsOne tab. all your items should still be checked. if they are not, the fix was never applied.

if they are, and youre not getting results...too bad bud. haha. sorry to say. everyone gets different results. if you care, i am using dcd 3.0.4 and radio 3.42.30, and my GPS works like its nobody's business. after a soft reset, GPSgate starts and connects to 9 or 10 satellites before my today screen can finish loading.

[veloslave]

Mine was working great... initially for a day or two and then it was back to bad... maybe even worse than before.

I rechecked the settings... all is good there, just long to no fix on any satellites. I don't suppose the new program listed on post 178 would make any difference?

[kflipproductions]

i find theres nothing to jumpstart a GPS better than a good old soft reset. im thinking that ports on the 6800 work just like ports on a PC. once the port is in use, if its not properly disabled, it will lock up until it is forced to open again. ive been searching around for some kind of port manager that can open/close, or enable/disable ports, but i cant find anything yet. a soft reset just closes out any communication the ports have with any software, so a utility that can close/open ports at will would make soft resets for GPS a thing of the past

[kflipproductions]

while i'm lookin for this, i discovered a cool little trick that works more often then not. thanks to the assholes at verizon, we need to prime our GPS. i use Google Maps. after opening the program, whether i have an active data connection or not, i select 'Use GPS.' then, i pan the map (very little) until 'Seeking GPS satellites' becomes 'Loading.' it seems to speed the whole process along, and 6 times out of 10 the GPS instantly turns on(blue dot), and locks within seconds to at least 9 or 10 satellites.

I have read in other posts that putting the phone into airplane mode then back out again will do this. I had no luck that way. I agree a soft reset has been the best fix for GPS not connecting. I also think quickGPS does NOTHING. I haven't used it in quite sometime. I use 3.42.30 Radio, DCD 3.2.0 kitchen and TOM TOM 7. I get fixes in less than 30 seconds nearly every time on a brand new 6800. Lovin the latest radio. None of the fixes have ever worked for me. The only fix that works is patients!

[ande8150]

Great Fix, worked for me. Went from zero sats in my apartment to a lock on 3 sats and this was the only thing I changed. Fantastic - can't wait to test it on the road.

Folks, I have an EnV with cable and QPST. What is it that you need??

Hope I can help.

[PapstDFrisco]

GC,

Thx for all the effort - this process has been very interesting. I'm a techie (EE) but a noob to all this phone creative upgrading stuff. So it's been a lot of trial by fire/error and reset/retry and move on.

So, after going through all this, I'm too wondering if I've missed something. I'm wondering about the Primers mentioned earlier. Are they a necessary evil for those of us on Vzw? Did I potentially miss a step in the install upgrade process.

I'm using the HTC GPS Tool & quick GPS. It appears that the quick tool only needs to be run periodically? Also, I rarely - maybe I should say never get a lock the first time I run the HTC tool - it usually takes a min of two and sometimes more. I will get/see upto 9 sats but none lock in?

I just put on 3.56 and upgraded radio to 3.42.30 then put on dcd 3.2.2 with the dcd verizon carrier cab as the 1st item in the uc script. After that I did the QPST GPS fix.

So, I guess I'm getting more sats found and it's locking more often - but I'm not sure that I'm getting the process or if this is what's to be expected or what? Maybe I'm overcomplicating things.

What should be typical for a vzw titan - say in an open area - reasonably ideal conditions - lock time - # of sats etc.... How is this quantifiable?

Are there any consistent steps to getting a lock?

Please chime in, I'd like to continue the path or stop chasing my tail.

Thx - MP.

You don't need it. All of the Sprint phones have this already.

Ok so I'm at Figure 6 but none of the image links work.

I looked at the original settings of my LG EnV. Under GPSOne tab, all of the check boxes are grayed and checked, sort of how the Titan was. Under the IP address it was 0.0.0.0. I am going to look further tonight and compare the two phones. I can't remember if the original back up of the phone was before I purchased VZ Navigator or not. However, there are a couple of tabs, (going from memory right now because I am on different 'puter) with other settings and one of them had the selection "mobile". I'll post later tonight or tomorrow.

was that while you were connected to "gps"? or just what was under there when you checked them?

id imagine, for the 0.0.0.0 do be filled with something useful its have to be running gps, or faux gps or whatever its running to locate you.

[bonkj]

I tried this method with no luck (I own two XV6800 and neither will get the internal GPS to work) and tried to roll back the changes. No problems connecting to the phone with QPST and I can load the backup of my original and shows the greyed out GPS portion (stock config). Then I write it to the phone, do a reset and check throught QPST (loading from phone) to find out that the settings have not changed back to stock (greyed out).

Anyone else experienced this problem? Just a suggestion would be to include instructions on how to roll back to stock (even though it is fairly obvious) on the wiki.

Any help is much appreciated......

-J

btw, I've got a XV6800 that I've completely disassembled to fix (pretty easy) and would be willing to monkey around/provide help with how to work on the internals if anyone is interested...

[hinds73]

Hello,

Just wanted to post my results, even though they did not match any of the prerequisites. The only reason that I am is because I was scared to try it, but really wanted a functional GPS. My GPS has always worked, but was really slow to get my Garmin up and running with the first lock. After I flashed no2chem's kitchen, my GPS would take anywhere from 5 to 15 minutes sometimes to get a lock. This to me was unusable! I found the wiki, and wanted to say THANK YOU GC! I can now get locks usually in under 10 to 15 seconds even after a soft reset. I don't have to use any other software either.

Rom: no2chem 5067
Radio: 3.37.20
Carrier: Alltel

Thanks,
hinds73

[aguas]

if it matters to add this anywhere, going to stock Verizon radio/rom (and possibly the relocker) will undo this fix. it needs to be reapplied if you go to stock.

I tried this method with no luck (I own two XV6800 and neither will get the internal GPS to work) and tried to roll back the changes. No problems connecting to the phone with QPST and I can load the backup of my original and shows the greyed out GPS portion (stock config). Then I write it to the phone, do a reset and check throught QPST (loading from phone) to find out that the settings have not changed back to stock (greyed out).

Anyone else experienced this problem? Just a suggestion would be to include instructions on how to roll back to stock (even though it is fairly obvious) on the wiki.

Any help is much appreciated......

btw, I've got a XV6800 that I've completely disassembled to fix (pretty easy) and would be willing to monkey around/provide help with how to work on the internals if anyone is interested...

Same problem for me :-(

GPSMODE=4 DOES ABSOLUTELY POSITIVELY NOTHING FOR NON SPRINT CUSTOMERS WHETHER YOU APPLY THIS FIX OR NOT

I have seen and read the Prerequisites and I have went through almost all of the 20+ pages but my Q is I am running a 3.56 ROM and I dont really see anyone else saying they are using this as most are 3.2.x. So can I still do this or not. My radio is 3.42.50 and just for clarification I have a xv6800
