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] no signal and data when installing latest pacman rom

Please help noob here and I'm having problems with the latest ROM from pacman 4.4 build. Every time I install I do not get any data or signal. Also when I try to sign into Google even with WiFi on I get message saying unreliable connection or I'm not signed up for data if issue persist to contact customer service any help will b appreciated.

What build are you trying to install, have you tried re-downloading the ROM also if you're trying to flash a different kernel with the ROM you have to let it boot once before doing so.

Downgrading back to kitkat

Well after being plauged with all kinds of issues on various 5.0.x ROMs I think I'm ready to head back to kk. Everything from Bluetooth issues to dropping calls to message duplicates to no messages to no group MMS and everything in between has occurred on my poor G3. I'm just wondering if there's any issue with downgrading. Right now I'm running a rooted stock 20B.
If anybody has suggestions of a super stable 5.0 ROM I'm all ears but I've tried CM12 (nightlies) which I had the most faith in and then the stock thinking "there's no way this could be messed up". Clean flashed them both multiple times and still having an array of issues.
Sorry for the rant just frustrated right now with a fantastic phone because I had to go and mess with it lol
Cheers

Well anything other than stock is based on CM. So bluetooth is basically useless on those roms if you use a headset for calls. If one rom has an issue than most likely they all will so I generally stay away.
Stock 20b has been just fine for me though. I would suggest a kdz to 20b if your still having issues. Are you using stock messaging because the issues could be with your 3rd party app with texting issues?
Its basically CM, 20b or 10r. If you can't get 20b to work right for you then your best bet is to go back to 10r and be done with it till 20c is released.
I pesonally don't use CM based roms due to the camera and bluetooth. Too many issues with those yet.

I might kdz to 20b and see if that helps. I was reading about that last night. I've tried all messenging apps including stock. No luck. I've messed with the APN settings and then gone back to stock. No luck. Kinda banging my head against a wall here lol. I'll probably kdz tonight when I get home and fingers crossed that'll work. Thanks

I am in the same boat as you. I wanted all the bells and whistles of the CM12 roms but so many problems.
Planning to throw in the towel and get the Note 4.
I am currently on LP xTreme v1.0 and everything works on it so far. (Bluetooth, Wifi calling, Messaging, LTE sticks)
Did have a minor hiccup when sending SMS while connected on Wifi but it hasn't lately.
This will have to do for now until I go back to Samsung, they seem to have a lot of nice roms over there :crying:
Good luck to you.

krowley3 has released his version of LP rom based on stock LP. i have been running his v3.5 (kitkat) since it came out as I see no enhancements and too many issues with LP roms that have been released since. I will probably try his new LP version out in next week or 2 myself. Judging by the past year almost of running his rom...absolutely no issues and the most stable experience I have ever has with a custom rom...

Thanks for the info... Maybe I'll give that a shot before heading back to good ol KK

Unless you backed up your efs in twrp the modem will stay at lollipop. That is the only way to get back the KK modem. But hopefully others can chime if there is an alternative way that was recently discovered.

just flash the 10r kdz and it will take u back to stock and just re-root.... what i did..

GPS not working on SlimKat 4.4.4

Hello,
So I've flashed before Slimbean, but had problems with the "can't connect to camera" problem, so I decided to flash Slimkat 4.4.4 which fixed the camera problem.
New problem now is that i can't get any gps signal. I can turn it on, but no signal. Anyone have a solution to this, or is experiencing the same problem?

Hi, the link you provided points to build 4. You can find build 9 which is the latest slimkat here http://www.slimroms.net/index.php/downloads/dlsearch/viewcategory/1183-d2lte
This is the one I have for my Koodo I747M. *note camera seemed a little buggy in some instances, so I installed open camera. Seemed to work a lot better.

I'll give it a try, thanks for the help. Quick question, will this work on my phone model without bricking? I only tried the at&t not the d2lte.
Also can you send me the link for this open camera you were talking about for my device as well?

I'd imagine it should be ok, since we have the same phone pretty much I'm on koodo which is pretty much telus without the customer service hehe. for kitkat at the end of development they basically lumped a d2att, d2tmo etc together. (this has reverted for the lollipop builds out there).
The last OTA I got was FOB1, so you may want to go to stock to ota to the latest updates from telus. Just so you have the latest bootloader/firmware. But that's up to you of course.
It's a google play app open source, the slimkat one I had seemed to lockup when switching from front to back camera and from camera to video. https://play.google.com/store/apps/details?id=net.sourceforge.opencamera&hl=en
What are you using to flash them?

"The last OTA I got was FOB1, so you may want to go to stock to ota to the latest updates from telus. Just so you have the latest bootloader/firmware. But that's up to you of course. "
I'm using TWRP

Ah, ok I just keep a backup in case anything goes bad flashing roms. If you use TWRP to flash them it only affects the boot image, data and system. So if you have problems you can restore from backup nice and easy.
I'm swapping between a few right now. So far my only uh oh experience was when I tried to upgrade TWRP, no problems with roms. But I use TWRP as well, works great.
Basically the baseband version on our phone, it's the radio and bootloader. Before I had rooted it I had gotten the latest updates by checking for updates. It downloaded and upgraded to FOB1 (Baseband I747MVLUFOB1), then I rooted and played with flashing. Not sure if you made a backup of your original install before trying another rom. But it's not a necessity for slimkat, I don't believe.

First thing to try for GPS problems is taking off the back cover and snugging up all the little screws around the phone. Sometimes they work their way loose and the GPS antenna seems to be the first thing to suffer from it.
If that doesn't cure it you might need to flash a stock or at least stock based ROM and rebuild the nvram. Here's a link that describes how to do that if you need to.

Marsh-mellow Issues, hardware?

Hey there,
I was wondering if anyone could maybe figure out this issue which has been troubling me for about a month or so.
I have ran marshmellow before absolutely fine however decided to flash lollipop back on my phone as I felt the battery life was better.
Anyway, whenever I come back to any version of the Marshmallow roms, i'm greeted with not being able to set a lockscreen (lockscreen has crashed), I cannot uninstall apps without a force reboot and I cannot access the security settings on the phone without it crashing.
I've tried wiping pretty much everything and it seems to be on all roms. I've tried multiple from fresh.
Any ideas?
Much Appreciated

@zwalk - sorry for the late response. I did exactly that. Seemed to fix everything. I recommend trying 20f or 20g if it works with your phone as it seems to fix battery issues.
