CM9 aplha 4 GPS BUG/NO work - Samsung Epic 4G Touch

This is my first Rom everything was installed correctly but when i went to use my GPS it does not work. Is there a solution to this?? Not trying to spam just want to see if anyone else is having the same issue and if they were able to fix the problem

Known issue. The only known workaround is to flash back to a Touchwiz rom, get a satellite lock with Maps or GPS status, pull the battery (don't just reboot, actually pull the battery), boot into CWM, wipe factory/data reset, flash CM9, flash Gapps, reboot.
Has worked every time for me.

GPS fix?

My GPS wont fix and is terrible! I'm using the latest cyanogen mod nightly
I'm thinking about going to a older froyo sense rom, what's the best to go to if there isn't a fix available?
If there is a fix could someone point me in the right direction I can't seem to find it
Thanks

What radio are you using?
I am using 12.28e.60.140fU_26.04.02.17_M2 iirc.
I had a bit of trouble getting the initial fix once, but I just switched GPS off then back on, then opened Maps and waited for it to get that initial fix. After that, it was fine! Locks on really fast
radio 12.35d.60.140fU_26.08.03.07_M
Just flashed it but GPS never worked properly on any of the cm7s, when it did fix it would lose it every so often
Have you tried this: http://forum.xda-developers.com/showthread.php?t=989578
No luck still
here's what's worked for me on cm7 (i'm currently using 26.04.02.17_M2_SF but i've tried several different radios, they all work fine):
assuming that you have the correct country selected within gps.conf...
1. wipe delvik cache in recovery and reboot
2. ensure that you have either wifi or mobile network on. and of course, turn gps on.
3. download gps status from market and run it
4. within gps status, menu>tools>manage a-gps state>reset
5. within gps status, menu>tools>manage a-gps state>download
6. wait for it to get a fix (it can take anywhere between 10 seconds to a couple of minutes). the important thing here is to keep an eye on "Fix/Sats.". you should see this number start to increase as your gps starts to get a fix on different satellites. if you don't see any change in this, your gps is not getting a fix. reboot and try again.
forgot to mention...every time i reboot the phone, i have to run gps status again to get a fix. kinda annoying but better than the alternative (i.e. no gps). i hope this helps.

Again the GPS problem

Howdy,
So I'm another user having problems with GPS on my HTC Wildfire. I tried pretty much everyhing. Flashed all different radio versions via Recovery, fastboot and Android Flasher. Also I installed the agps patch. None of these solved my problem.
Before doing all this I had no GPS status bar icon at all. Now at least I have an icon showing me that he is constantly searching for GPS.
I also used GPS Test to clear and update AGPS but no luck.
Finally I tried several custom ROMS, from CM, to Splashmod and rempuzzle and all of them have this problem. So it's ROM independent.
What else can I try?
Fasterfix and gps essentials are the 2 apps that helped me fix my gps once.. and i had even used the agps patch by crypted for more accuracy

If you did all the above really clean - I mean with formatting/wiping/factory resets etc. it could also be a hardware problem in the end. But from my experience there are just a lot of pitfalls why solutions won't work.
The fact that you didn't get the icon show up before but now it does looks to me that it's not a hardware problem. My suggestion would be to reflash either the radio and the ROM again - but as clean as possible.
- look into "The Complete Wildfire Index" thread (in "General") pick the radio in the middle and flash that first
- do a clean wipe of at least the system partition, cache and dalvik-cache (I also do "format system" and sometimes a "wipe all/factory reset" to be sure and it couldn't hurt to wipe data also - your decision)
- flash the ROM you want to use
- flash gapps
- reboot and look what it does (this most likely won't do at that point)
- flash the newest of the 3 radios afterwards and see if this helps
--- Edit --- to flash two different radios is a dirty trick to remove leftovers or problems because wiping or formatting doesn't touch the radio --- EDIT ---
For testing GPS I suggest GPS Status from the market (best tool in my opinion). You could delete ags data as well with it.
The agps patch (I'm using it too) is just for optimization (to get faster responses) - it won't help if your GPS doesn't work at all.
Hello guys,
I finally resolved the issue and realised that GPS was working all the time well. However, I always tried to search for a signal inside a building in front of my computer and was not aware of the fact that the signal might be too weak to be received from within inside...:silly:
Anyway, the flashing method apparently did the trick!
Cheers

[Q] [help] GPS toggled on - searching indefinately for sat's

Need some help with troubleshooting a problem that started after installing Slim Bean 2.8, though I don't think it is the fault of the rom.
A few days ago I got tired with the ICS custom rom I had on my phone and decided to try one of from the original development section of this forum. The GPS worked flawlessly so far, turing on the toggle on the status bar and then going into google maps would locate me within 5 sec. The icon for the satallite would also show up in the status bar.
Then yesterday I flashed the Slim Bean 2.8 and was super exited about the look and feel of the rom, but when I tried to use navigation the app kept saying 'searching GPS signal'. I then tried toggling the GPS icon in the task pane and even re-installed the rom and performed a factory reset, but nothing helped.
Today I installed a GPS diagnostic app from the play store and while it says GPS ON it never finds any satellites. Then I performed the last desperate move and flashed the stock ATT rom with root inejcted via ODIN. Still GPS is not working.
Am I missing something? Could it be that the phones GPS is defective?
Any help is appreciated. Thank you.

I'll give that a shot. Just hoping I can remember which one of the leaks I may have installed. I'll report back if it works and send a thanks your way.
Flash to stock lg1, unrooted. Then do a factory reset from the settings menu, not recovery. Pull everything off your internal card that you want to keep, this will erase/format your internal card
******THIS WILL ERASE YOUR INTERNAL CARD*****
I had the same problem after flashing a sprint based leak. But, that procedure fixed everything for me.

Sure enough I flashed back DG's JB Sprint leak and the GPS icon is back and locks within seconds. Now I just need to revert back to stock and then reinstall one of the CM10 releases.

Proper GPS fix

I've seen quite a few "flash back to stock, then flash AOSP" fixes to get your GPS working. All you have to do to really fix the GPS is:
1. Backup your stock ROM's EFS through your recovery. (Do NOT wipe prior to doing this.)
2. Wipe
3. Flash AOSP based ROM.
4. Restored your ROM's EFS through your recovery's advanced restore.
Done.
GPS is my ROM's Bane!

So, I am having a GPS issue that I've been unable to solve through any of the numerous method's posted around XDA (my primary source of all things android) and related sites. It could be a simple solution, but I've exhausted my very limited knowledge and am hoping you have some input or suggestion...
I'm on the LS970 and in an over-caffeinated moment, I fully wiped the stock ROM without a backup. I know that is totally stupid, and have been much more careful with my fingers since then. :silly: I have been unable to get a GPS lock on Spleef's Carbon 4.3 20131020 (or any previous), so tried to factory restore and TWRP flashed a ZV9 ODEX (failed install), ZV7 STOCK (failed install) and SPR-ZVB which flashed successfully but gave me FCs and reboots everytime I opened an app that would get a GPS lock. I have tried the FasterGPS, GPS Status and Toolbox, and edited my GPS.conf. Since I can't get back to factory, I need another way to get to a "factory-enough" for a GPS lock...
Any ideas? I think maybe there's a path/process to follow to be able to go from AOSP to stock that I'm not doing, but I have no idea what it is.
Fingers Crossed!
I was having the same issue with Bean Stalk then carbon also. using the app GPS essentials it would show 0 satellites in the sky even though GPS was enabled.
I flashed the Optimized ROM in the DEV section and this did bring back the GPS functionality.
just an FYI since your stock ROM is gone.

You have SAVED MY WORLD!! HUURAAAAYYYYY!!!!!! :highfive:
The OpTimized ROM was PERFECT in bringing back my GPS, it locked in seconds. It took me a few tries to get it active on Carbon4.3, so I'm going to give my "steps" for successful completion.
I FULL WIPED before flashing OpTimuS_V4.4 (ODEX) - that's Data, System, Dalvik and Cache. (Obvious? I first ran a full TWRP Backup of the system, data, boot)
Then I flashed, booted, and let it go through its process. It took its own "soft reboot" which I thought would turn "Bootloop" but it did NOT... rebooting to the "Semi Stock OpTimuS" perfectly. It did the "Activate" process on its own.
Then - I went to System Updates. PRL first, then Profile. Then the VITAL UPDATES were Google Maps and Play Services.
After this, I rebooted to let it reacquaint, and then installed FasterGPS, using it to clear the current aGPS. Next, installed FreeGee.
Opening the updated Google Maps, I IMMEDIATELY got the lock, but let it sit for 5 minutes. (reset "display time" to 5 minutes to keep track.)
Next - AFTER the GPS locking for 5 minutes, I did a backup of EFS with FreeGee. If you have PREVIOUS BACKUPS on the Internal Storage, they need to be replaced. This can be easily done with ES File Explorer, or any which allow root access. Go to the active (sdcard on LS970) FreeGee, copy the EFS settings, and replace those in the "/0" or Legacy FreeGee folder.
This may be "overkill" but I went back into Google Maps, got a Lock again, let it sit a few minutes and "tested" the navigation function.
While still in Maps, I powered down. Booting into Recovery (I use TWRP), I ran a RESTORE of my TWRP Backup, since the backups aren't "install" compatible. My fear was the "Restore" would override my updates, but when you run it, just "uncheck" EFS in the restore choices and you're :good:.
My LS970 booted up LOVELY, ran its normal boot process, and when I opened Google Maps .... ~*Aaaaaaaahhhhhh~* light from the Heavens! It locked FAST, and the Nav even worked!!
I have been trying to find this Fix for almost TWO MONTHS so I am on Cloud 9 right now!! Thank You @etownguy!!!
GPS locking issue
Hello all,
I am an intermediate novice at flashing, but Ive gained some knowledge over the recent years here and there. Heres the issue, I am running into the same issue as euphoric fuzion except I have exhausted all that I know. I rooted, unlocked bootloader and flashed my ls970 without creating an official Rom backup or backing up my EFS- I know, not bright of me. After using my new roms I realized that MY GPS isnt locking. So, Ive done everything from writing new NPS locations in gps.conf, attempting to go back to stock via LGNPST-Ive used the auto option, Flash tool and they dont seem to recognize my phone via download mode but the drivers are installed-pc recognizes. One flash tool actually recognizes my phone as another model. Ive tried to flash stock based Roms-one ins particular at no suceess-symlink failure. Attempted to flash ZVC stock based Rom with Firmware flash- the phone remains in bootloop from my previous ROM. In order to use the phone I have to reinstall CM11- my fav for now- but I cannot lock my GPS with out SPrints PRL update, or network update for my profile. Any suggestions? Thanks in advance

GPS device only mode not working after flashing custom roms

Hello I'm wondering if anyone had this problem. Obviously GPS was working on stock and when i flash a custom rom afterwards it works however but slowly. Then if I decided to try another rom, GPS breaks entirely, I've tried editing the gps.conf to remedy the problem but it was no use. So now I'm back on stock from a TWRP backup but now I'm literally confused as to why this happens.
Both data and system partitions are wiped before each install...what the heck is causing this? Does it matter to have a gps.conf file since everything is commented out (in AOSP/LOS roms) if you actually look in it with a text editor...
On Razr, solution was to turn on GPS and then reboot to recovery flash custom rom, etc. Later we figured out better solution.

The thing is though GPS is turned on by default no matter which option you get with during the setup wizard. I've never turned off gps between flashes.
Well, then that's not the problem. I've just shared experience...

LineageOS gets new GPS in the next update
And initial fix can take a while
