Hello,
I am running cm10 b2 on my e4gt and i am having the most difficult time getting a gps fix. I did a nandroid backup then flashed back to el29 and then back to cm10 b2. And after I booted back i got a gps fix. However several hours later I get no fix despite multiple resets, battery pulls, and clearing and redownloading the a-gps data. Does anyone else have any suggestions on what I can do to fix this problem?

Hey guys,
Don't shoot me, I've already done the research and still can't seem to find an answer. Regardless of ROM I can't get GPS to find any satellite's, fresh root, SR4.2, Synergy RC2, CM7 nightly, MIUI, Virtuous. I unrooted to see if it was a possible hardware issue, which it isn't as an unrooted phone gives me fast locks onto whatever sat is near. GPS Status shows nothing in the sky even after a A-GPS reset and download, although I know there's always at least 3 that are visible. I've tried clearing cache for any gps based app, tried running fresh rom installs instead of backups all with no luck. Any ideas guys?
Currently I'm running:
ROM - SR 4.2
Baseband - 2.15.00.07.28
Kernel - Stock Kernel from SR4.2 (2.6.32.17-g9a2fc16 htc-kernel[email protected] #1
PRL - 52341
HW Version - 0002
CWM - 3.0.0.7
HBoot - 0.92.0000
Radio - 2.15.00.07.28
Looks like I'm stuck going back to stock unrooted until I can get this fixed.
I'm having the exact same problem. Tried multiple roms and doing A-GPS resets. I'm not sure what else to try, anyone have any other ideas? May have to unroot for now so I can use GPS while traveling.

If you are in NY or other new 4g area it may be related to a problem others are having with AGPS upate VZW pushed. No ROM seems to work.
yep, it was an issue with New York. We drove to Boston on Sunday, I tried clearing my A-GPS in western Massachusetts and suddenly got a lock on GPS! Google maps then worked perfectly all the way to Boston.
Well there is no way I'm giving up root or custom roms, Google or Verizon need a better solution than that.
I actually fixed mine and never left NY, I dropped to stock then went back to SR 4.3 and haven't had a problem since, and I've flashed 3.0 roms and SR 4.3 multiple times with no problem. So if you're still having a problem unroot then reroot. It should fix it.
Okay so I have CyanogenMod and I am still running nightly 56. About a month or two ago, my screen became unresponsive in certain areas. I was told that it was a hardware issue and required replacement, but I am really unsure about how to unroot, so I haven't returned it to stock. Today, as I took my phone off Airplane Mode, the dbm signal meter read -1 and I had no service. No matter what I do (battery pull, wipe cache, on/off airplane mode) I don't get signal. Has anybody else experienced this before? Or do I finally need to face my fear of unrooting my phone and sending it in?
Are you still rooted and running cm7? did you play around with the network options in settings? This sometimes causes no signal issues if not done correctly. I would try flashing 56 again after you wipe cache and dalvik, or flash the newest 100 nightly or cm7 stable build, both which have been reported to work now.
I have always had issues with cm7 on my inc2. From the earlier days to current versions. It is like my phone doesn't like aosp tons. I always have inconsistent signal and my highest battery drainer is cell.

So you think this is a software issue, not a hardware issue with the radio? And is it okay to jump from nightly 56 to nightly 100 without a full wipe? Thank you so much for your help.
yes it is ok to jump without a full wipe. just wipe cache and dalvik. and the only way to tell if its a software issue is to try different roms. try a newer nightly and if that gives you problems try a sense based rom and if it still doesnt work then it might be a hardware issue.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
Okay. I overcame my fear of unrooting and I'm stock now. The signal does work, so you were right, it was a software problem. My screen is still unresponsive though. I switched to stock, but my phone is now 2.2.1. Will that be a problem for returning it for a replacement?
Yesterday my gps wasnt working at all. It would not lock on no matter what I did. I was on a custom rom and I tried wiping my data/cache, reinstalling maps (just for giggles), and a multitude apps from the market that help deal with gps problems (gps fix, gps status, toolbox, etc).
When all this didn't work I decided to odin back to the last official JB update and still no gps. On a whim I decided to odin back to an ICS firmware and that made my gps work. I have no idea but it did. I then odin to UVDLJC, installed TWRP's most recent and restored my backup of the custom rom I was using in the first place and gps now worked.
While I'm happy as heck that my gps is now working and that it was not a hardware issue I'm extremely curious what happened.
I have flashed many roms lately and I cannot think what a custom rom can do to gps to hose it or if it was just one of those things. I would of thought that when I originally did an odin to UVDLJC that would fix the issue but that didn't. Whatever the flash to ICS did fixed it but what in the heck could that of been?
I figure if I can find out or get an idea what happened then I can steer away from flashing certain roms, or just be prepared that flashing any roms at all can make this happen again.
Same here.
Hello, ddcoh.
I am currently having the same issue you had with GPS not working. I've tried everything from trying tedious Play store apps to trying many different roms and kernels (clean installing every time) to completely reverting back to stock including using TriangleAway in case that did any help. Nothing worked. I have been thinking about going back to ICS to see if that worked but the last time I tried to downgrade from 4.1.1 to 4.0.4 I ended up soft bricking my phone even though I followed the steps word for word.
Can you tell how you went about downgrading to ICS and then back to JB, please? I use my GPS a lot and I would hate to find out it's a hardware issue.
Typically, it's been when people are going from 4.2 to 4.1.

Well I used odin to flash an T999_UVALEM which was a prerooted ICS rom. After booting it up I checked to see if GPS was working and it was.
I then used odin again to flash T999_UVDLJA which is a JB rom and booted it up also and saw that gps was working. Then I just restored a backup of a room I had been using and GPS still worked.
I've been out of town and noticed that after flashing a few roms that gps wasn't working so instead of doing all the above stuff I just flashed a cm10 rom. I believe I either used a cm10 nightly (or maybe 10.1, memory is hazy) or LiquidRom and that got the GPS working by just doing that. Not sure if that will work for you but you could always backup your setup using TWRP's latest and then flashing a cm10 rom and seeing if gps is working and if that fixes it then you could then just reboot and restore the rom you are currently on and that might fix your gps for you.

Hello everyone, just got a quick question to ask.
I was running CM10 stable and had a problem with my SD card a while back (which I never figured out), so I decided to preform a clean wipe of CM10.0 and a stock rom as a troubleshooting method.
I finally stuck back with CM10.0 and I've been rocking that install for some time, but have a problem. Every fifteen minutes or so the phone's cell connection would drop completely then pick back up a min or so later. It's very temperamental and I have no idea what was causing it. It never inhibited the utility of the phone, so I just dealt with it.
Today I flashed a clean install of Paranoid Android, gs2usr's unofficial version, and it still has the same issue.
I've flash different modems and the issue still remains, but I have no idea where to troubleshoot beyond that.
Any ideas guys?
|EDIT| Solution was taking it back to stock by flashing with Odin then re-rooting and flashing CM10 stable. No issues so far!
I'm not sure what happened but at some point a month or so ago my GPS stopped working on my phone. Using google maps is uesless and it keeps losing gps signal and cannot find where I'm at.
I've tried a full wipe and insall of the latest CM11, changing to different modems, wiping cache and nothing seems to help. I'm very frustrated as for work I need GPS. Please help me!
Can you get a GPS lock when using a stock ROM?
No it will figure out where im at initially but when I move it does not move and track me even on stock 4.1 cdlk3 Modem
You were running CM11 with an LK3 modem? I read other posts where people were having problems getting data with the 4.1 modem and CM11.
No I was running cm11 but went to stock last night. Im on 4.1 with lk3 modem and it cannot locate me or track.
Is there a utilty to completely wipe the phone and put it stock or id there something else I can do?
I thought the latest version of CM11 required the latest bootloader and modem.
What bootloader is on your phone?

Have you tried an app like GPS status to reset and re-download GPS data. I've had that fix issues in the past for me. Also I've heard the screws on the back of the phone may get loose and negatively affect the GPS so you could try tightening them(gently).
Yup I tried a couple programs and nothing pics up a gps signal whether outside or in a car.
Is the gps linked to the modem?
This should solve any GPS issues.

I found a backup from back in april and flashed it just to see if it fixed it. GPS lock worked great so something in the wipe/flash/radio combo got screwed up.
A week ago I dropped my phone and the lcd screen broke but I figured i'd update the thread in case someone else has issues
Thanks for the help guys the apps were awesome!
