Can someone please instruct me how to get GPS up and running again? I am on latest nightly and have tried various past builds. I installed the new modern, I have cleared the cache several times, dalvik and otherwise. I have even factory resetted several times. I use GPS allot because I work for FedEx. Any help would be greatly appreciated.

I hope this will work for you. This worked for me. I don't pretend to understand all the details of what went wrong, but from what I understand there's a non-volatile (ie factory reset, reboot, etc won't fix it) privacy setting on the GPS which, when activated, basically breaks GPS. Samsung must have realized this was stupid too because the latest stock rom/modem doesn't mess with this setting anymore. Unfortunately, if it was set before you upgraded to the newest modem, that means your GPS is stuck in privacy, aka non-working mode (stupid because if you didn't want GPS you should just turn it off).

So what you need to do is backtrack to a combination of software that DOES mess with this setting. Once you are SURE GPS is working again, you can consider flashing the new stuff again (you may have to try more than once because there is absolutely no user control of the privacy setting, another stupidity in the system).
So
1. Flash either an older stock image (newer stock image contains the same privacy bug so you can't use that) or older cyanogenmod and modem. For stock, I recommend the original firmware released with the phone https://dl.dropboxusercontent.com/u/103520801/T699UVALH1_T699TMBALH1_T699UVALH1_HOME.tar.rar
That is what fixed mine
You can try the following version of cyanogenmod + modem

https://dl.dropboxusercontent.com/u/103520801/RelayLJ1modem.zip
2. Do a battery pull and wait a minute. Just to clear out anything that might be lingering.
3. Obtain a solid GPS fix. Install GPS Status and stand outside. If GPS doesn't come back at this point try the other route (cyanogenmod or stock)
4. Turn off GPS.
5. Battery pull, do not power off
6. Flash forward to cyanogenmod (build 111 or higher)/newer modem. You can try restoring your nandroid (at this point mine worked with a restored nandroid) but if GPS goes away again try with a fresh install.
7. If you obtained GPS on stock but cannot get GPS going in cyanogenmod try repeating again but replace step 4 with "do battery pull while you have a solid gps fix"

Thanks nardholio! It worked like a charm. Any chance we will ever see photosphere? If not it's no big deal. Just curious.

dillalade · May 3, 2013

Thanks for this tip Nard.

I did this.
1) Created a nandroid of my full wiped build 111 install/setup
2) full wipe install of 20130309 build

Got GPS to lock.
Turned GPS off.
Battery Pull.

3) Without wipe, nandroid restore of 111 build.

Reboot, GPS works.

Thanks again :thumbup:

Sweet that fixed it right up. I did these steps, in this order:

1. Nandroid backup from CWM
2. (From CWM) Factroy reset and cleared cache, then flashed this file(rom): http://goo.im/devs/nardholio/apexqtm...L-apexqtmo.zip followed immeditatly by this one (cell radio) https://dl.dropboxusercontent.com/u/...ayLJ1modem.zip
3. Booted into cyanogenmod.
4. Downloaded and installed a recent googlemaps.apk
5. (Switched off wifi) Obtained a solid GPS fix
6. Turn off GPS.
7. Did a battery pull, did not power off just pulled the battery..waited 1 min and put the battery back in.
8. Booted into CWM recovery (by presssing Home, Volume Up and Power) and flashed the nightly build #137, immedetally flashed the MC5 Modem from this thread, and then after that finished immediately restored my nandroid backup.

GPS is working and my phone is still setup like it was an hour ago. PERFECT!

Thanks Nardholio :highfive:

kilr00y · May 20, 2013

though the reason was me misreading when i applied the fix, but i kept GPS ON. which actually - from a logic pov - is the thing that makes sense to me.
and it worked fine.
all you others switch it off once you've gotten a good gps fix.
and it works fine as well.

but it really raises the question what the real issue behind this problem is..

Nardholio · May 20, 2013

No "real reason" mr conspiracy theorist. Cycling the setting after getting a GPS fix makes sure its set the right way when you upgrade to the newest rom. Otherwise you don't know what state the chip has been left in

which makes it russian gps roulette

i guess, whatever works...

gee one · May 23, 2013

When you guys are saying GPS is broken - do you mean it doesn't work at all, or just takes a while to get a fix? Mine is slow to lock and the compass is off kilter, but eventually it will lock.

kilr00y · May 23, 2013

nah, it never locked. he just kept on searching for satelites forever.
The first lock after i went back to the latest build took a little but after that fft was like 5 seconds. and still is.

MIA on all files

Hi,

All of the original firmware files seem to be MIA. Does anyone have an alternative link to the original modem?

Thanks

Worked perfectly.

1. Backup CM11.
2. Wipe all partitions.
3. Flash CM10.1 and Modem.
4 Pull battery.
5 Boot CM and install Google Maps
6. Set GPS to device only and open G Maps
7. GPS WORKS!
8. Reboot to recovery (forgot to disable gps)
9. Wipe partitions and restore CM11 backup
10. GPS WORKS!

I am however on baseband T699UVLJ1 and I believe T699UVBMC5 is the latest one.
All seems to be working so I will leave it like this for a day and then update and test GPS again.

Flashed to the latest baseband again without any problems so far

After I managed to bollix up my GPS, I went through the steps with CM (the link to the stock rom is 404). I flashed the 10.1 gapps as well, and I used GPS Status instead of Maps, but I did manage to get GPS working again after restoring my backup. Thanks a bunch!

I must say, my Avant has a vastly better GPS than the Relay, but (for now) the Avant is completely stock/unrooted.

And why does it not work with a CM11 image?

I cannot find any CM10.1 image, links are dead! :/

----
Right, going back to CM10.2.1 and after that back to CM11 also worked.

Phone never booted in CM10.2.1 by the way... CM boot circle was going round and round for 15 minutes... Removed battery, tried to boot again, same thing. Went into recovery mode, luckily I still had a CM11 ROM zip on my phone. Installed it and works! Some Trebuchet error message popping up though and Google Play services crashing all the time.. Hmm we will see what can be done about that. Maybe because I used a July nightly.

Need help

I need serious help to fix my GPS. I want to follow the steps, but all the links are dead. So I have no idea how to obtain 10.1 or original stock firmware to fix gps.

Anyone can help with the files?

Gps
