[Q] GPS Issues - Trying to root cause - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

First let me get this out there that yes I searched the forums and did find information on how some people were getting GPS issues and some recommended solutions/fixes from other users. However I think my issue is somewhat different and I am trying to get an understanding of it. (please if you do see that a similar issue has posted elsewhere that I missed, I apologize in advance and ask you to point me to that thread).
Currently I am on JellyBean747 by (Drewgaren) ROM based on Sprint leaked JB (L710VPBLJ7). This is the only ROM where I get my GPS working. I have tried swapping ROMs to other leaks, Official releases, AOKP, CM10 with no luck. Tried changing the kernels with Ktoonsez's Stock kernel but still no luck.
I have a nandroid backup of stock+root ROM which I used to get root. Even restoring to that ROM doesn't fix the GPS.
I have also tried turning GPS on before opening maps, used GPS test app and another GPS fix app to setup servers to North America etc. Still no luck on other roms. GPS doesn't even start.
JellyBean747 by (Drewgaren) is the only ROM where I get the GPS working properly (or should I say normally?).
Does anyone have any idea why is that? and what is different in Sprint based rom that might be interfering with GPS files/libs etc.
Any suggestions, pointers, comments would be appreciated. Thanks.

gps fix
go here http://forum.xda-developers.com/showthread.php?t=1995347
follow all of the steps exactly.. gps now works on all roms. if you have more problems.. reffer back to here http://forum.xda-developers.com/showthread.php?t=1995347 worked for me :good:

I tried those steps on AOKP with no luck. Since you are suggesting to try it again, I will but this time on LK3 based ROM to see if it works. Can you please share which ROM you were using and having problem with GPS and then were able to fix the GPS using these steps? Thanks for help.

I went back to stock and no GPS. Followed all steps with no luck. Like i said, my hardware is working fine but there is something in Drewgarens rom that is causing GPS to not work with any other roms. Please suggest another tip. Currently i am on AOKP and GPS is gone.

[Q] GPS on 2.2

I've tried the GPS on several of these ROMS, including the Stock 2.2 Leaks and have been unable to use GPS. The functionality of the 2.2 is great, but if I can't use Navigation and general GPS, it's bogus to me. Is anyone else experiencing this? I've Googled it several times and searched here, only to turn up brief mentions. From what I've gathered, it only affects a handful of folks, and I'm one of them.
I've been using the leaked OTA from 7/21 I believe, and have attempted to use CM and Incredible Does with no success.
Current kernel is 2.6.32.15-g936f65f
Check which Baseband you are using (Settings>About>Software). You are probably running 1.00.03.xx.xx
In order for the GPS services to work correctly with 2.2 you need to update to the 2.x radio. Instructions towards the bottom of the OP: forum.xda-developers [dot] com/showthread.php?t=737400
Sorry for the poorly formatted link. I'm still not authorized to post links.
Try the 8-1 leak. That will upgrade your radio.
Here is the link
Also try this One of Hydra's Kernels
Thanks. I will try these. I thought maybe I had done this before but doesn't hurt to try again.

(HELP) T-mobile GS2 GPS Location WAY Incorrect

Two days ago I installed BeastMOD Extreme 5.0 and everything was working fine until today that I noticed that my GPS is getting incorrect location. I Live in Puerto Rico and it says I'm in Nevada. WTF? any fix for this? help please!
Use faster fix app. It can see more satellites
Sent from my SGH-T989 using xda premium
Could be something with the rom. I would highly recommend you try another rom and see if you have the same problem if you use GPS occasionally.
OR
Try to re-flash the rom and don't forget to use Darkside Superwipe to get rid of any problems you may encounter.
Are you using AGPS patch from the dev section ? It could be the culprit, as I had similar experience with it...If you are first try restoring your gps.conf to stock gps.conf (its in /system/etc, use root explorer to navigate to it). If it still doesn't help, try changing the ROM
In my experience, juggernaut 5.0 has best GPS performance of any ROM I've tried till yet if you want to stick with gingerbread...For ICS, try dan brutal's Sirrus rom, its performance come close to juggs but I still stay juggs has the edge...
Although I don't know, why the GPS is varying among ROMS, as I've made sure I use the same gps.conf everywhere..ideally it should be same..
I think it was a Kernel issue. I installed Synergy .10 and it worked like a sharm. Now i'm running an ICS rom and works fine. thanks for replies!!!

GPS not working after CM10 stable install

Hello all,
I am having issues after installing CM10 stable on my T989. My GPS doesn't lock and can never find my location.
I am sure this is a radio issue, but not sure what the best radio is for this rom / device. Also, can I install the radio without having to reinstall CM10?
If someone can please recommend me a radio, that would be great. Thanks :laugh:

Thanks for the reply. I installed the T989UVLI4 radio and everything has been working great! I tested my GPS today and it was perfect in CM10.
I also need to mention that I was having GPS problems because by default, CM10 had all the location services off by default. So if anyone is having the same issue, go to you're system settings, then location services and turn them all on.
I have the same problem GPS doesn't lock in CM 10 for me too I use Optimus Black

[Q] E975: Problem with GPS fix when using other rom than the stock

Well I have serious problem with the GPS when flashing other ROM than the LG stock. I have tried lots of ROMs like CM11 nightlies, vanir, carbon and none of them have working GPS. I have downloaded GPS Status apps and they give me no fix. With stock rom I have fix within 10-15 secs even the first time. The problem is described here.
I suppose that it has to do with google services and the gapps pack I flash (the banks one) but I can't find a solution.
Thanks! :good:

[FIX] GPS issues on ASOP based ROMS

If you are having issues with GPS on AOSP based ROMS all you need to do is:
*flash a stock ROM (stock ROM is one based on the LG ROM that came with the phone I recommend this one http://forum.xda-developers.com/verizon-lg-g3/development/rom-stock-root-deodex-t2932683 )
*get a gps lock
*then flash or restore whatever AOSP based ROM you like.
GPS will now be working for you.
This has been a fix for GPS on AOSP based roms for years and I had to recently use it myself as I was getting no GPS on all AOSP based ROMS.
Also make sure that GPS isn't actually broken in the AOSP based ROM you are flashing because if GPS is broken in the ROM then obviously this isn't going to fix it. This fix is for people having GPS issues on ROMs that have working GPS which is currently all KK and LP AOSP based ROMs we have for the vs985. Hope this helps someone.
bump. Still seeing people posting about no gps on AOSP roms so bumping this in hopes that it gets seen more often.
Interesting. Just curious here: If I "Restore" a 4.4.4 ROM, get the lock, then Restore back my current AOSP Lollipop-based ROM, will that work? As in, is the GPS lock sequence stored in the GPS hardware flash or something?

Honestly I don't know why this fixes GPS I just know it does. Like I said in the OP this has been a fix for GPS on AOSP based ROMS for years as I learned this trick back a couple years ago on my LG Spectrum. I was one not getting GPS on any AOSP based roms but noticed most weren't having issues with it so I remembered this fix and tried it on my phone and I haven't had GPS issues since. Once you do this you should no longer need to again no matter how many roms you flash; just be sure to always get a lock on each ROM you flash before flashing a new one as that may cause the issue to comeback.
Bumping again because people are still constantly posting about gps being broken on AOSP based ROMS and don't know how to research the forums for solutions to their issues but would rather clutter threads with the same questions over and over and over.
Help
So does "get a gps lock just mean open up maps and get it to lock onto a gps signal?
