[Q] Flashed Incredible, lost all location services

Hello everyone,
I've been a lurker here for a bit. Some time ago I used Unrevoked, did something wrong installing the original FroYo update and screwed up my phone. I migrated to the DX in the meantime, but this weekend I wanted to return to the Inc. I successfully revived it after a lot of trial and error.
Now my issue: I have tried several ROMs including SkyRaider and Cyanogen, but my location service is not working. Not in Google maps, search, not for weather widgets, nothing.
I'm not sure if this is related, but I have tried a few different radios thinking that could be the issue, but its not. Also, I can only seem to get a working earpiece with the V1 radios.
Any ideas on how to get my Inc fully functional again?
Thanks.

Try the latest RUU. Short of a brick or hardware problem, that will fix anything.

Search for Bezerker7 and Ultimate get back to stock thread, that'll explain how to flash the RUU and get back to stock, see if location services work on stock 2.2 unrooted, and then you can re-root and flash ROMs.
EDIT: Here's the link.

I'm assuming that this phone is not activated as you have the DX? If its not activated and on the Verizon network then it can only get a location through GPS which may or may not be turned on. I would check to make sure your GPS is turned on in the settings, or use a toggle widget, and then try Google Maps again. I also think the weather widgets don't use GPS as the default and that may have to be set in their settings too. They get their location information from the carrier.

Thanks guys, this worked! Any clue why it happened in the first place?

If you didn't wipe data, then all sorts of crap will happen. You're lucky if you don't bootloop. I bootlooped even when I flashed the same rom and same version over again and didn't wipe data. So maybe it wasn't that.
Maybe it was just something left over, CWM not wiping or something like that.
I really hope it wasn't a hardware defect that subsided for a while

[Q] GPS problem - very strange

I have a GPS problem, and despite reading a number of the threads in the forum and trying the usual fixes (downloading GPS Status, clearing downloaded data, re-downloading A-GPS data, factory reset, upgrading to 2.3.3 etc...) I still figure out what's wrong.
Symptoms are:
I do have a GPS icon in the task bar in the apps where I would expect it appear
I never get a lock
Both GPS Status and GPS Test seem to indicate I have *no* signal from any sats
I am outside when I try this
aLogcat seesm to show no NMEA data, though I've never read a logcat entry for working GPS, so I'm guessing a bit here. It does show GPS start up and shutdown lines however
It didn't work in 1.84, when I downgraded, and it still doesn't work in 2.3.3 - seems to be version independant!
Does anyone have any bright ideas? It's really irritating. As a side note, the phone isn't rooted (as I forgot to S-off when I upgraded to 2.3.3) though it could be downgraded fairly easily if there was a good reason to do it...
Thanks!

If it has never worked and you have wiped the device, re-installed etc....
Then I would guess that it may be a defective unit...

1. are you running custom roms? if so which?
2. have you updated your radio and made sure that the RIL is matching?

1. Nope. The stock 2.3.3 RUU and before that the UK T-Mobile Stock 1.84 ROM.
2. Stock only, so standard RIL.

That is my fear. It did work when I first got it, but it now doesn't on any ROM. Unfortunately I can't quite work out what changed...
If this is the problem, does anyone know a way to get back on the T-Mobile official ROM so i can take it back to the shop?

Hi there, Your best bet would be to try and downgrade, root and flash a matched ROM, RIL & radio to retest. This happened to me a while back and this was the only thing that sorted it. CoreDroid has been particularly good for GPS on my DHD, hope this helps

Yeah - I tried the Coredroid rom - no dice. Think that confirms it's hardware. Back to stock and then back to the shop for this one.
I heard rumours that early DHDs were flaky for GPS. Guess that confirms it for me...

Had exactly the same problem with mine after using the gingerbread ROM from here http://forum.xda-developers.com/showthread.php?t=1056329
Are there different versions for different countries? Maybe this only works in the US or something? I'm guessing here!
Are there different stock ROMS for different countries/ networks? I didn't write down the version numbers before updating

[Q] did my radio update break my gps?!?

So I've been running cm7 for a while now with no problems at all with my GPS after the sense GPS fix. Today I updated my radio prl pri combo thing and my GPS only locks for 1 second or so then even the icon dissapears. So I flashed cm7 over itself and its still broke. Anyone know a good combo for the GPS or a fix?

Have you tried the re-doing the "sense GPS fix" you mentioned? You can asking try shutting down your device, pulling the battery, reinserting the battery and then powering up your device to see if that helps.
posting & replying via the XDA Premium app.

Yeah I've pulled the battery more then once. Does anyone know if updating radio combo ect... would make me need to do the sense fix again?
Because that's a giant pain in the ass.

Hi, did you ever got your radio to work again? I have the exact same problem now. I tried an old rom (Floyo 1.2) and thought I might as well update the radio. I did a full wipe and everything went fine, but I can never get a GPS signal. I have tried GPS status and toolbox -> reset -> download assist data but to no luck. Then I tried six different radio versions (old and new), the Floyo Euro GPS zip, the Salsa rom and Elelinux' 2.3.4 rom but none of them works. If I try to let GPS status keep running for a minute or so, the phone will eventually do a hard reboot :/

Try and flash back to a sense based rom and reflash the updated radio and then update your prl reboot and update your profile do that twice should clear up your issues.

miui-us I'm having issues with GPS on CM7 as well, but I never got it to work with a sense fix or anything...I'm going to see if I can get it working when I flash a sense rom first. If it works then I'll try what you said.

Same thing happened to me after updating the radios. Looks like it's time for the PITA Sense and back fix.
Trying it now, but it takes about an hour, I will get back to you....

[Q] Weird GPS problem. What happened?

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.

GPS not locking or finding my location

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!
