Lost GPS ? And how to get it working again.

I have seen a variety of posts in various threads about people not being able to get GPS connections and blaming the ROM they were on the for the problem - I imagine that sometimes that could be the reason but something happened to me recently that makes me wonder...
I am a flashaholic - often going back and forth between various ROMS via Nandroid back ups - all was good - then recently I noticed my GPS wasn't working. I thouht it was the rom - but no matter what I did I could not fix it. I tried installing other roms - totally clean install - I tried flashing back to rooted stock and no matter what I tried, GPS did not work.
I don't know where I saw it, but I finally saw a post from someone who suggested fixing it by going back to stock via odin - I tried that and it didnt work either - digging a little deeper someone suggested using odin to going back to pure stock then go into settings and do a factory restore.
I tried it - and it worked - took me virtually all day to figure it out - but it is working better than ever now - I wish I knew what caused it in the first place - but at least I found a somewhat reasonable solution.
If you have lost your GPS and can't get it working again - give it a shot -
Does anyone else have any other suggestiions that might work?

This is correct. I had this exact same issue and this worked for me as well.

Do you know why it happend in the first place? Was it the result of a specific Rom or just flashing in general?

Thats what i found that worked for me too. It only worked after i went into settings and reset the phone after odin.

I recently lost my GPS after flashing a Sprint-based ROM. Unfortunately, ODIN back to stock and factory reset from the Settings menu (and from recovery) did not bring back my GPS.
However, I followed a suggestion from this thread:
http://forum.xda-developers.com/showthread.php?t=1923067
I used ODIN to go back to a rooted stock ROM, installed CWM, installed the Sprint-based ROM that seemed to have been the source of the trouble. My GPS started working again. I then used CWM to restore a stock nandroid backup I had from earlier and GPS continued to work thereafter in any ROM I flashed.
There may be a simpler process, but that's what worked for me.

Now that I thnk of it, I also had flashed a Sprint Based rom - that must have triggered my original issue - I explained what I did to restore my GPS at the start of this thread _ and it is similar to what you described - execept I did not odin to a SPRINT rom - I used ODIN to bak to pure stock - then did a factory restore - (and this second step is what seemed to do the trick) then I re-rooted and went backto my happy days of flashing roms - I haven't had an issue since.

Well...that may not be the cause but it's a common denominator. I did and I had to flash back to stock and factory wipe to get mine back.

It definitely seems to be a common element to most of these GPS issues. I'm not sure why, in some cases, all it takes is a factory reset in stock to fix it, while others have to re-install the Sprint ROM first. Either way, though, it seems like in most cases, it's user-fixable.

Got the GPS death syndrome today. Flashed a ton of stock ICS nandroid backups without any luck. Finally fixed it after flashing a Sprint JB ROM nandroid then back to ICS. Such a werid issue.

Why flash a Sprint ROM on an ATT phone though?

Because its the only official US Jelly Bean released at the moment.
It was one of the many backups I had. Don't know why it fixed it but it did.

I have the same issue. Now to flash a stock rom using Odin, do you have to use the toolkit? Also where can I download a Rogers stock rom from?

finally after losing gps and reading thread after thread got it to work , thank you to the guys that personally try to help , dont know why it struck this time but it did , now i will try to bring it back to stock , again thanks , by the way the rom i was using to bring it back was serenity 1.1 which i use before but wouldn't stick...:good:

If your problem started after installing a Sprint-based ROM, then root your phone, install CWM and then install that same Sprint ROM. Your GPS will probably work after that. You can then restore a Nandroid backup of another ROM. That's how a lot of us were able to fix our GPS.

[Q] What is wrong with my Gnex?

Hey the Problem is the following:
3-5 random reboots every day
restarts during every phonecall after 1-3 Minutes
freezes when in standby, cant turn back on -> need to take battery out
often slow, especially when switching apps. or when typing
I have tried stock 4.3, CM10.2 recently and before that CM10.1 for a while.
I already send it in but they only said my battery is broken.
Is it possible that all my problems come from this?
I rather think my flash memory is broken? What you think?

Since yesterday I am facing the same problems you are describing. At first I thought it was a bad flash or something like that. Clean installed various 4.3 costum roms and it's always the same.
Right now I will look deeper into it since the phone is unusable in that condition.
If I find a solution I will comment.
Best regards
Edit: Okay, works again flawlessly. I simply flashed an nightly from carbon-rom and the lags were gone. Hope it helps. What exactly caused the lag I don't know. For now I am staying on 4.2.2 Carbon as it is my favourite rom anyway and I will wait till there are stable 4.3 from carbon.

Are you sure it's the phone and not an app?

Not pretty sure, but it still occured after countless factory resets, wipe cache, wipe dalvic cache and wipe system via TWRP.

Have you tried a clean install without installing apps to see if you get a reboot to eliminate an app as a possible cause?

Yes I did. I only flashed for example newest PA and their PA Gapps.
So far I resolved it by "downgrading" to a 4.2.2 nightly from carbon. The lags are completly gone. I will stay and wait till carbon has stable 4.3.

why dont people try stock when they are having problems? going from 1 custom rom to the next does not prove it is the phone.
please fastboot flash the stock rom and do not restore any apps/data other than say your google acct

Already did that.

I am having the same/similar problems with my GNex too. Specifically bullets [1-3] from the original post. I am running unmodified yakjuux and have tried with just my google account with no other apps and the same problem exists.
Mine makes a noticeable "click" sound with a vibration followed by a reboot.
It usually happens during calls and after it boots the phone call log shows no record of the incoming/outgoing call that just happened. Its like a blue screen of death for android!
I have sent the phone back to Samsung's warranty service 4 separate times and each time they reported no trouble found in the completion report. They just factory reset or put an older version of jelly bean back on the phone and send it back to me with some notes of PRL updates and other nonsense to make it seem like they did something to fix it.
Does anyone have any suggestions (logs, adb, etc) how I can help prove to Samsung/service absolute that the phone is a lemon (other than trying to video tape the phone hoping it reboots - because that is the last resort)?
I already escalated to executive customer service and they refused an exchange because the completion reports show no trouble found :crying:
Thx!

well... I also have this problem.
First happened when I flash Cm10.2 nightly (don't remember which one).
Then I flash PA, or whatever... Looks like the random reboot relating to notifications? It's usually happened when whatsapp notification coming in, but not always.
But a few weeks ago I flashed stock ROM rooted (via TWRP, not fastboot).
The problems solved. No random reboots anymore. Then today I tried latest CM10.2, and it happened again... Wonder why... Looks like it's a very rare problems.
Interesting to see someone having the same problem...
Now I want to flash stock ROM via fastboot to check if it'll fix.
Btw, I can flash directly to CM 10.2 from 10.1, can't I? Or I should flash 4.3 via fastboot first?

I believe CM offers an upgrade option somewhere in the system settings. Unless you want to wipe your phone and flash directly to 10.2 in which case I do not think you need to flash stock 4.3 first. Maybe just do a reset within 10.1 before you flash CM10.2 via whatever recovery (clockwork etc) you are using but even that may be unnecessary.
My 1 year warranty expires this month so if I can't manage to get something out of Samsung I am going to play around with flashing stock 4.3 as you suggested. I have tried converting yakjuux to yakju in the past but still saw the problem then which made me revert back to yakjuux so I could send the phone back for service).

Wifi issue on AOSP Roms

Hi guys,
I have had the s2,s3,galaxy nexus,original note and i am used to flashing and modifying,but i have a serious issue with the note 2.
The problem is whenever i flash AOSP rom(cm,aokp,pa) my wifi would not connect.It shows the name of the network and when i click conenct nothing happens.Flashing back TW rom fixes it,wifi works like a charm. I've done full wipes but it doesn't seem to resolve the issue.I tried different kernels,but that doesn't help either.
So I am stuck at TW roms and i hate that.Anyone has any ideas?

You can try options 2 and 3 from this thread.

Thanks for your reply,but i tried this and it didn't solve my problem.

Anyone?

I Have the same problem...

Not sure that it will help you but I read something yesterday about this issue.
The solution was to NOT restore your Google profile during first boot so you should full wipe and try again.

This actually has nothing to do with the problem.
After a few days I finally found the cause ,and therefore,a decision to the problem.
It is the bootloader from 4.3 sammy leaks.It seems that this new leaks(probably the reason being KNOX) cause malfunction of wifi in aosp roms.What i did was ODIN flash stock MG1 from sammobile .This brought back stock recovery so i had to flash TWRP again and it solved the issue for me.
Before that i had tried changing roms,kernels,recovery,modems and nothing worked so I am pretty sure it is the new 4.3 leaks bootloader.
Some people will say that it can\t be the issue because they are using 4.3 sammy and do not experience the same problem on aosp roms,but i think thats because they flash it through CMW ,which doesn't change bootloader,while flashing through ODIN does.

With my Note2 this is not the solution. I've tried everything. What you said, move file "pit" ..... but nothing. I can not connect wifi. The connection does not appear region Spain, and have opted to choose europe, but neither. I do not know to do. CM 10.1 also does not work WIFI. In Stock ROM or Custom ROM works fine fine, but in ROM CM 10.1, 10.2, AOKP don't work.

[Q] Flashed ROM to 4.3, Nandroid back to 4.1.1, now no camera.

Help, I brokeded my phone trying to use this ROM!
I recently tried to flash the 4.3 Stock MOD ROM to my ATT S3. It wasn't smooth for me so I Nandroided back to 4.1.1. and now my camera does not work and I get an error that says "Cant connect to the Camera" or "Camera failed" depending if I use the Jelly Bean Camera or the Samsung camera.
No fault of the ROM I’m sure but I need help figuring out what I’ve done wrong. I switched back to my Nandroid backup of 4.1.1 Stock because 4.3 was just NO smooth for me. Also I can’t stand regular keyboard, I need my Samsung Note 2 keyboard!
4.3 had a lot of laggy-ness and random crashing. I flashed the Modem, ROM and Kernel in the order with the steps listed per the OP.
When I decided to go back to my backup, I flashed the DLK3 Stock Modem, then flashed back to my backup and wipe the various caches.
Everything about my backup works BUT my camera. I also noticed I can’t use the flashlight option on my 4.1.1 ROM now. Anything related to the camera is broken.
I’ve tried killing and clearing the camera process per several articles I found on Google and here on XDA without luck. Everything suggested it was a hardware issue at that point and to warranty the phone. I deiced to try 4.3 one more time and sure enough, my camera works when flash back to Anroid 4.3 ROM.
I’m stumped.
Any thoughts sort of reinstalling 4.1.1 from scratch?

You have to have the bootloaders for 4.1.1 for the camera to work in 4.1.1. This happened to me a while back with 4.1.2. There's a thread here somewhere where you can download the correct bootloaders and flash with ODIN.
EDIT: Here's the thread: http://forum.xda-developers.com/showthread.php?t=2321310
You need the DLK3 bootloaders (well, that is if you have the AT&T gs3) for the camera to work.

[Q] T 210R help need to downgrade to 4.2.2

I upgraded to kitkat through OTA update and it screwed my tablet up. It kept freezing and restarting by itself all the time to the point it was useless. I did a factory reset and couldn't get it past the boot screen and if it did it froze seconds after getting to the home screen. I called Customer service and told them I was having issues because of the update and they said I could send it in for $99 and they would repair it....... yeah right. So I decided to root it, I used Odin 3.7 and twrp then flashed it with nolekat I thought I had it fixed but it started doing the same thing again I am feed up with 4.4.2 and want to go back to 4.2.2 where I had no issues I cant find a clean stock rom for the 210R and was wanting to know if someone could point me in the right direction. Thanks
