COULD MODs CARE ABOUT GPS error here - a long time has fixed for many guys

[vqscorpions]

Hi Mods!
I really sorry that I have to open new thread, because I and some others also posted here

http://forum.xda-developers.com/showthread.php?t=405016&page=4

but it seems that no one can solve that problem correctly. And MODs seems that don't know about that problem.
So, could MODs give us some ideas and solutions.
For example: I used Original ROM, GPS with TT7 was OK.
But when I change to another ROM (any other ROM), it was so good that everything works well but not GPS.:confused:
Hope to hear from u soon.
Thank you.

You do know about the problem with validating maps for a new installation of TT7 ?
Do a google for this in xda -devs.

thanks friend
My problem is here.
When I bought x7501, I installed TT7.45 with Map of North America. It work fast and better than Kaiser I had.
Then I tried to Up ROM to SPL 3.5 (every ROM for 3.5) and I could not use GPS. TT7 work but it only show the working screen with: Waiting for valid GPS signal... forever. And when I find the GPS position, it says: Poor signal.
I tried to change Radio version but failed.

I also tried to convert back to SPL 1.2 now and working with Official ROM 6.0 (but with SPL 1.2 Oliprof). I tried to change Radio version, from 1.47 to 1.57 to 1.58 but failed. So strange (because I had to format the drive when I convert back from SPL 3.5 to SPL 1.2 so I lost my backup file for SPL 1.2 for original ROM).

Now I can not receive GPS signal.
I also try to install GPS Proxy,but this program doesnt run in my Athena, it says: Negative exception and quit.
I aslo try to change th port for GPS to another COM port, but it will not turn on GPS device.
In my Athena, the default COM port for GPS is COM4.
So, that's my problem.
Could you help me with detail instruction.
So thanks and wait for your help

thanks friend
i hope it will work
i try it now then tell u later
but do u mean that it works for AP 4 only? or another rom?

[lakeman]

i am confused because your sig says you have radio 1.57 but you say in your post above that you couldn't upgrade from radio 1.47.
AP4 needs at least radio 1.50 according to here http://www.htc-hackers.com/uploads/AP4_How_To_1.8.pdf

Steps are optimal for michy roms,ap4 gps should be blistering fast "out the box"! When I used ap4 I was using radio 1.57,and even indoors I had gps fixes in 30 secs after soft resetting.
As of now I use radio 1.58 for hsupa on michy 6.1 rom and have fairly good gps.The steps above emulate my settings with exception of rom.

Hi friends
Firstly, so thanks to all of my new friends, who were trying to reply and show me the way to solve the problems.
Secondly, I want to give u the good news. Now GPS is working as a champ.
But it is a little bit difference with some guides from u.

- I follow the steps above and change the baudrate to 9600, but after reset, it comes back to 4800 as default.
- The COMPORT for program is COM 4. For the hardware, I set default is NONE.
- Then, I install VisualGPS.BeeLineGPS.v1.83.Build.125 and reset. After that I run Visual GPS Beeline first, it works after 20 seconds and lock my location when I stay in my car (The weather now is -1 celcius degree outside - very cold).
- Then I run TOMTOM, I choose BUILT IN GPS (but not other NMEA). And TOMTOM works perfectly after 10 seconds - I did that because I remember that I always chose BUILT IN GPS when I used TT7 with this one two weeks ago.

And here are some tests after that:
- I turn on Wifi, open DATA connection (that is a issue when I use Kaiser, if Data connection is opening, TT7 can not receive the signal), then open TT7 (without openning the VISUAL GPS), it works after 12 seconds.
- I come into my room (the second floor in a three floors house) and turn on TT7 without using any other software, it lock after 10 seconds with average 5-8 sats.

WOW. It can't be better.
But I still don't know which one help which one. Because, when I installed TT7, then I run it for the first time yesterday, it said: could not run because of the memory available.
Then I try to run GoogleMap (even if I did not connect to Wifi - so ofcourse GoogleMap only turned on but did not run with data), then I tried to open TT7 again and it run (confuse here, who can explain to me)

The problem only now is.... WIFI. I hope can fix it soon as the instructions from CMONEX.
Thanks friends.:D:D

just a minor correction to guide after you stating baud rate returning to 4800, in external gps settings on hardware tab to change baud I notice you need to set hardware com port to com 5 first then setting baud to 9600 ,then click ok to save.Go back in external gps settings and back to hardware tab ,as you will notice settings saved but now this time select none in hardware port and leave baud at 9600 then hit ok.

As I remember in ap4 4800 baud was default and worked best with that rom anyway,and so far it works for you.I do recommend setting use other nmea in tomtom input your baud and software com port settings from external gps control panel because you used visualgps to boot up your gps to get sat fixes for tomtom, with these settings you dont have to use visualgps to warm it up.Make sure you update your quickgps evrey 2 days then soft reset and hold phone by window or go outside when you use gps with new emphemeris file from quickgps as it can take a lil bit longer to regain track ironically ,but once you get fix itll be super quick no matter where you are,even if you soft reset.The only time you need to have clear view of sky again to get sat fix is if you turn off device completely for an hour or 2, or update quickgps data agn in 2 days (up to full 3 sometimes) or flash a new rom :>.

For wifi,I dont kno how to fix,cmonex prob has to send you a special file to regain mac address so wifi can work even after spl changes.
