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.

GPS on 4.3 rom issue

Not sure if its just a issue I am experiencing or does happen to to others. This issue only happen on 4.3 roms let it be cm Roms or gpe Roms. Also I have tried different developer Roms and same issue. The issue that I'm having is GPS randomly stops and locks and is more noticeable when in long trips. This has led me to revert back to any 4.2.2 ROM and all is well. Has anyone else had this issue? I've tried wiping and formating internal drive different restore recoveries such as clockwork mod and twrp and same issue. I feel I don't miss much from 4.2.2 and 4.3 and why I don't mind staying on 4.2.2 but just find it very odd.

Yes ive also expirenced this with 4.3 roms. I also reverted back to the 4.2.2 roms because navagation is important to me. So you are not alone in this experience. Im not sure why this problem occurs however I can confirm it is happening. I do wish I had a resolution to this issue as ive tried many things with out success. Hopefully someone can resolve this issue in the future. hope this helps. Best wishes.

I've had this problem on a 4.2.2 ROM as well... after flashing a 4.3 ROM it went away, but I'm on another 4.2.2 ROM now and the GPS is fine. I'm not sure it's related to 4.2.2/4.3 in my experience.

Yea, I've now noticed it happens on both. Quite sparatic. I have no idea what to do about this. Thinking about just getting a new one from tmobile.

[Q] no wifi or blue tooth and I've tried almost everything.

Well I started off with the jedix roms and wifi and blue tooth were working fine. updated to jedix19 or 20 and wifi and bluetooth were spotty, sometimes they would turn on sometimes after turning on it would turn off or just lose BT connection.Went to skynote rom and same thing. went to mean bean same. also same when going to ezkat. I just updated my bootloader to the mk6 without knox stuff and tried flashing the wifi fixes with odin but still no wifi or BT. Is there someway of getting wif and BT back? Thanks for the help in advance.
Edit: oh yeah using an att i317

I have the same problem, I already did a thread, I hope that someone could help us

Did you ever find out?

Maybe a lil more info will help.. Yeah I read everything you tried to flash.. And nothing working.
You can try flashing AGNi kernel for working Wi-Fi. You can find it HERE»»»

Anything with 4.0.0 is for kitkat.
Anything 3.9.7 is for 4.3 fyi.
Since you tried the rest it's time you tested the best lol. It's still beta but very stable btw. Go here»» http://goo.gl/hnP1sV

And if I'm not mistaken....both DN3 and eZKAT require the same fix for wifi....
Agni kernel flash is the preferred method...g

this is an old thread...but fwiw the only solution for me was to flash the complete stock att ma4 4.1.2 rom ...and then work back up to whichever rom of choice.
this was after trying multiple bootloaders, kernels, modems, recoveries, roms...4.3, 4.4, etc.etc...
i did find another flashing combo that seemed to fix things but after a period of time wifi/bluetooth would randomly disappear again(!) and i'd have to repeat the whole process over again. strange.

I had tried going back to 4.1.2 rom & went all the way up and it still didn't fix the wifi/bluetooth problem.

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!

Upgrade broke the GPS

Hi all, I have a note 2 shg-i317 that was originally on Bell in Canada. It was unlocked and the aws mod done to it, I use freedom mobile, aka T-mobile in the states.
I was running a Rom for the past 3 years Slimfast 4.4 and liked it. I had tried Nugat on another phone, thought I would try the [ROM][7.1.2][OFFICIAL] LineageOS for N7105
I did the upgrade, broke the root, could not get a few things working, so I decided to restore the Slimfast backup I had just made (complete including modem etc) and everything works except the GPS.
GPS for me is huge, I use it a lot. I cannot lock on to 1 satellite now. Before i was able to lock onto a minimum of 16 in about 30-45 seconds, if outside.
I really dont care if I can get to 7.1 at the moment. I need my GPS back - any troublshooting for getting GPS to work on this phone?
James

I would try to flash the original stock for your phone and country from sammobile. com
Gps should work normaly then. If not your hardware is broken. If it works you can always flash your data back from your Slimfast rom.

Crap, I am posting here, because I did it again. Again not sure how. I tried to run Reserection, and I guess that messed up the GPS.
To put the original stock rom on.. I have to do that through ODIN? I dont remember how I fixed this last year.. Sorry.
Hope somone can help I need the GPS.
James
ps. Used odin 3.09 to flash the original rom... still no GPS

You flashed the latest 4.4.2 room?

The Rom that I flashed to try and restore the GPS was I317MVLUDNF1_I317MOYADNF1_BMC (mine was an originally BELL phone)
But that did not repair the GPS from me flashing resurection.. I THINK did it. I flashed an android 6 and an android 7 rom. (Mokee) but tried to go back to my Slimfast.. and the GPS was now broken.
Basically what I did a year ago.. somehow I fixed it then.. but cannot remember at all how I did it.
James

The note 2 sold by Rogers, Bell, and Telus are exactly the same model and stock roms from these carriers can be cross flashed.
Try flashing the stock ROM twice in Odin with a factory reset in between each flash.

Do you mean boot up the rom.. run the reset in the rom? or flash.. - load TWRP back in.. WIPE.. then FLASH again with odin?
Thanks for helping btw.
James

I have backups (complete all partitions) of my rom.. Slimfast 4.4 from 2-3 days ago.. when I tried this. SO.. if I can get the Factory rom to restore the GPS.. how can I restore the backup.. I saw somewhere that the EFS partition could be left out and that might help? dont restore the modem? how??
James

I meant flash with Odin, boot into stock recovery, factory reset, flash again with Odin, boot into stock recovery, factory reset, and boot into the stock ROM.

Nope, still no GPS lock.. I have the flashing circle (always had) and it will not lock.. I read about where people go into a service mode and rebuild the NV? .. I assume this is something that Mokee or Reserection did.. not sure how.
Any other ideas?
James

what about using Odin or TWRP to put different modems in? does the modem effect the GPS?
tried this.. does not seem to. grrrrr wish I knew how I fixed this.
James

I assume there are no loose wires. Does it get a lock when using wifi? Not sure what else to suggest.
Not sure about rebuilding NV.

No.. I broke it with playing with custom roms.. Liniage was last year.. I did not try that this year.. but tried both android 6 reserection and android 7 Mokee.. and I am pretty sure they messed it up.. I am also pretty sure there was something I did .. easy like load an old STOCK rom and it fixed it.. I was then able to put my slimfast 4.4 back over it and it was fine. Unfortunatly .. not enough people still using this device.. I will have to have patience I guess.
James

So I have tried differenct stock roms, but I think the issue is ODIN will not restore code from a rom image that is HARDWARE based. I wanted to use Samsung smartswitch but they disabled the part of it that allowed you to factory reset the phone, this seemed to work for several people. Many have also reported entering a code and going into a service mode.. there you can do to a menu that will rebuild hardware modules back to default. But I have not been able to get into that mode because it seems to be a touchwiz only option, and I cannot find a factory rom that is touchwiz based for this model.
What needs to be done is a true FACTORY ROM image.. that would revert all software and hardware back to original, but I cannot seem to find that anywhere.
James

The only factory roms that I know of come from places like sammobile.com and they are all based on TouchWiz which is Samsung's launcher.

So guess what? put Ressurection back on.. and the GPS is back.
I cannot get it to work in any KitKat based rom.. but now anything Marshmellow up.. works.. HMMMMMM
