[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] MaHo_66:
Hi all !

Since a week, i had a GPS problem with my i9305, it happened after i had flashed couple of AOSP roms, i dont know after which one it was exactly, the problem was that it couldnt get a lock onto my location, also couldnt find any satellites in any GPS fix/testing apps avaialable in the playstore, it was showing the blinking GPS icon on the left side in the statusbar, but there was no lock, it was endlessly blinking/searching for nothing.. Ive switched many times between AOSP and Samsung based roms, but this was the first time i encountered this kind of problem, which took me a week to figure out how to fix it :silly:

I tried many possible solutions such as, full wiping the rom, factory resetting within the settings, flashing back to STOCK rom with Odin, tightening the screws in the back of the phone, resetting and updating AGPS, changing GPS related files and libs in the rom, trying different roms etc. etc. with all to no avail !! :(

Then i did some research on the net and found the solution that worked for me, surprisingly it did even fix GLONASS that wasnt working before the problem occured, now GPS works perfectly fine! :D

SOLUTION:

1. first we need to enter service mode, this may differ for various android versions (4.3 - 4.4.4 - 5.1.1 etc.) just search for the right method if it is different. I did this on my android 4.4.4 KK ported note4 rom (Eclipse ROM)

Note: be sure the rom your doing this on, has the ServiceModeApp(_RIL).apk installed in system/priv-app, otherwise you wont be able to get in service mode!

Note: also if you dont have a sim password set, your phone might get sim locked, so set a pin password before doing this, afterwards you can always disable it again if you want..

2. in dial pad enter *#0011# to get in service mode

3. to unlock the main menu: press menu --> press back --> press menu --> press key input --> enter Q0 --> press ok and wait for the main menu to appear

4. now, press UMTS --> press COMMON --> press NV REBUILD --> press Restore Back-up

5. your device should now be rebooting and after that GPS issue should be fixed hopefully :) test your GPS with any app from the playstore..

Steps 3 and 4 pictures:

GPS problem fixed

Hey,

and thank you soooo much for your helping advice :D

I did like you said and voila, GPS problem is history.

But what problem I still have is that I can´t flash any 5.x.x custom ROMs. Flashing goes well, but when it is time to reboot, my i9305 stuck to somekind of loop. I can flash stock ROM 4.4.4 and custom ROMs 4.4.4 as well, but Lollipop doesn´t work.

First time I had this problem was when I flashed some 5.1 ROM ( I don´t remember what was it :( ) But in that ROM suddenly happen that "Google services has stopped" or something like that. I couldn´t do nothing with phone. That error came again and again to phone´s screen..

So I was in situation that I had to flash stock 4.4.4 stock ROM. eveything went well, but GPS didn´t work anymore. Then I found your advice and I thought that now I can again flash custom ROMs as well. Flashing any custom 5.x.x ROM goes well, but in reboot, pghone stuck to loop.

Or had I wait longer in first time I reboot phone after flash?

Thank you so much in advance :)

I don't know if it is related to your problem, but I had many problems with 5.X.X builds boot looping because of wrong gapps package. For example, using PA gapps with CM12.1 or Resurrection Remix causes a bootloop, but just flashing the rom and rebooting doesn't cause any bootloop at all. You might want to flash just the rom and let it boot. Cheers

To all using this method, if your device has been unlocked by someone,

THIS METHOD WILL RE-LOCK IT

Solutions:

You're probably on the knox bootloader, and to use the commands of that xda thread, you need a 4.1 rom.

But you can't flash a 4.1 rom because it will fail on the bootloader, so you need a 4.1 with 4.3 bootloader in ODIN format.

Here's one, fzeta is a forum member, all credits to him:

Flash the rom, unlock the device with the known commands, and then re-flash philz recovery by known methods, and you're done.

I have tried this but under nv rebuild I get "menu not exist current command 6611" so my GPS is still not working. Help
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Pe1ican0:
Guys I tried this on various stock based ROMs, it only worked for me with official 4.1.1.

Edit: I got it to work also with TGP v25.02 4.4.4 ROM with stock kernel & settings. But due to simlock, I had to go back to 4.1.1 anyway to unlock the phone... Better to do it all in 4.1.1...imho

Just did it today, it took me 5 hours of flashing & trying before I found another thread where some dev said it worked on 4.1.1 only. Maybe on 4.1.2 too but unsure. Then again he might have said that because of the simlock issue that is only fixable on 4.1.1....

I downloaded from sammobile a UK 4.1.1 release anyway, flashed it & all went well. GPS fixed then Simlock of course.

Luckily on 4.1.1, you can unlock Network lock. (For this however you must use the same menu but the function only works with 4.1.1. it doesn't work with any other ROM I tried including 4.1.2 & 4.4.4.)

Then restored my Android 6.0 from a TWRP backup.

You should know that it's possible to do the same fix by restoring a NV backup made with QPST. So if ever you have made such backup before...you're in luck.

[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Pe1ican0:
You cannot get into service menu with a non stock ROM. The latest stock is 4.4.4 so it's normal it doesn't work for you.

You can use TGP 25.02 & during ROM installation choose stock ROM & kernel.

However if you go ahead with this you should know it's likely you will get network SIM locked. Without unlock code the only way out of SIM lock is the service menu in Android 4.1.1 Stock. (use the UK one from sammobile).

In this case you might be better off doing both service menu operations in 4.1.1??

In order not to lose your current cm13 installation, you should use TWRP recovery to make a full backup (I like using a USB key but you can use the SD card). After backup, wipe the phone, install the stock rom (with TGP zip in recovery or with Odin if using 4.1.1), do whatever service menu procedures as required, if you flashed 4.1.1 then reinstall twrp recovery with Odin, reboot into recovery, wipe phone & restore your backup. Voila...

[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Pe1ican0:
Yes I can help but you didn't answer my question, which way do you want to use to fix GPS? By restoring a NV backup or by using the service menu?

All the explanations about how to use the service menu to restore GPS can be found in this thread in OP & previous posts.

The service menu can be accessed from stock rom/stock kernel up to 4.4.4. The only problem comes from the possibility of SIM lock. If you don't have a SIM lock network code, you are likely to get stuck. In this case, you must either get the code from the operator or you will need to install a 4.1 stock rom to unlock the phone with the service menu.

Restoring a NV backup can be done with QPST, which can be downloaded from dedicated threads. If you don't know QPST, you probably don't have a backup though.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] OMINIS:
Probably opted for restoration of NV.

The NV is the same backup of the IMEI backup?

I think I have a NV backup, but I have to go look because I have done for over two years and I hope you are well done.

[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Pe1ican0:
Well check what you have. If you backed up the imei you likely made a NV backup too...

I was like you, I had an old backup from years ago. But when I tried to use it, I realised it was corrupted (the whole hdd was corrupted in fact!) so I had to use the service menu in the end.

And yes I understand Portuguese, I lived in Portugal & later in Brazil...

I have met the backup, is a .qcn file created on 26/05/2013.

Will fix the GPS fix and does not make any further changes?

I think the XDA rules only allow English language.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Pe1ican0:
If you have a good NV backup in your qcn file, restoring it should fix the GPS without further changes. You should not get a SIM lock AFAIK if the phone was unlocked when the backup was made

Let me know how it goes. If ever you got SIM lock for whatever reason, you can get out of it so don't worry too much.

Yes XDA is English only. ?

You have not read the OP & my previous posts properly.

If the service menu is not working like it should, it means your ROM is not stock <=4.4.4 + stock kernel.

The requirements are not met.

Flash the right ROM & it will work fine.

The screws should always be tightened as a first step to repair/improve GPS. You can go from a fix with an average 7 sat to over 20 just by tightening the damn screws. I really mean tightening which buy the way requires a proper screwdriver of the correct size otherwise you will damage the screws for sure!

[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Pe1ican0:
To use the service menu fix you MUST use stock ROM & stock kernel <= 4.4.4

If you use a non stock ROM, it can only work if the ROM either uses stock kernel & settings originally or gives you the choice to use STOCK during installation.

If not, you may be able to see the service menu but it will not work.

AFAIK the service menu procedure is completely unrelated to the problems of gos.conf file & xtra command..

The service menu procedure restores the NVRAM data when it's corrupted.

When you don't get any fixes (or too few) but the NVRAM is still fine then you should first check the screws. If still not working, you should check the conf file & use the xtra command via a GPS utility downloadable from the Playstore. There are a few apps other than GPS status to do that.
