[Q] GPS not working

GPS seemed to have been working up until I flashed one of the CM11 or other Kit Kat roms. I've since gone back to CM10.2 (stable), but I can't get a gps lock. Does anyone have suggestions to get this working? I have the Verizon version.
I've tried resetting A-GPS data with the GPS Status app and also by setting the regions with Android Tweaker. Neither seems to have done anything. Really hoping my GPS radio isn't borked.

Just had this same problem, I had to flash back my original nandroid (stock ota) to get a gps lock, thought my hardware was crapped as well. But I am guessing if you dont use your gps for a long time it loses the info for sats. I tried flashing PA ram, gummy, CM11 nothing would get a lock, so I said **** it, going to return it, put stock image back on and wallah, it came back, reflashed my OSE rom and it worked, worked in pa again as well and gummy.
I also tried the gps fix lg g2 zip thats out there, nothing, tried the recalibration from 5 different compass apps and gps "fix apps" nothing.

I unfortunately lost my stock ota backup . I tried flashing this (http://forum.xda-developers.com/showthread.php?t=2533018), and I got stuck in the Verizon bootloop. I'm using TWRP 2.6.3.3.
I'm unfortunately on a Mac and can't follow the steps outlined here (http://forum.xda-developers.com/showthread.php?t=2432476). Any help would be great. This is driving me crazy!

Flash back the original 2.6.3.2, (follow the first twrp/rooting steps that you did, but minus the rooting, just the installing of twrp. Then flash one of the stock OTA images from the verizon forum.

I ended up downloading and flashing a Malladus ROM (based on stock). I managed to get a GPS lock after that (hooray!). I'd assume if I jumped back to CM now, I'd be all set.

[Q] Help. Please. Rooted s4 to custom ro

Hello,
I recently rooted my sgs4 gt-i9505 to the goolge edition using a YoTube tutorial on how to do so. Everything worked fine at the start but when I tried to install the PAC man rom, it jus stayed in the loading screen.
I restarted and tried rebooting but to no avail. I went back into the recovery mode and wiped the phone (divlac, cashes and system) then I reinstalled the google rom to find my wifi was not working. I tried the same process again, wipe- reinstall. Now I can't receive calls, the wifi doesn't work, home button only works on double tap, pull down status bar works but nothing in displayed.
My question is, does anyone have any ideas on how I would return my device to normal or know a full proof recovery and rom I can use that will correct these problems.
I am in the UK if that makes any difference.
Thanks for all and any help.

You could try to go back to stock and check if everything still works there.

Did you flash the correct modem/baseband for the ROM / your carrier? There is a thread in general for all the modems. Chances are with a KitKat ROM you need to update your modem. Read that thread and give it a go. The file is about 15mb and takes a minute to flash in Odin. Failing that go back to stock.
Nothing in status bar: that's what it looks like in stock, you can use 2 fingers for the quick settins. Installl WANAM XPOSED fromwork for more tweaks and options!!
Home button double tap: that's the way it works on the google edition, that's just it. BUT wanam xposed can change this with the Gravity Box module!! You could try the Echoe 2.2 kitkat rom it has xposed pre-installed.
Keep in mind things look blanker and less functional as you no longer have samsung touchwiz which adds a LOT of stuff to the stock experience!
One more thing: ALWAYS make a nandroid backup before flashing ANYTHING at all, you never know when you will need it. Backup the nandroid to your PC also just in case, things go missing/ get deleted! T

[Q] No GPS lock on cm11

Hey all,
I got my phone and immediately flashed to gr33nd3vil's cm11 rom using TWRP and ioroot. The biggest problem I'm experiencing is that I'm getting absolutely no GPS lock. I downloaded GPS test and it says 0 satellites in view and 0 in use. I tried copying some config settings from other gps.confs I saw online to no avail, as well as clearing/updating AGPS inside of GPS test. I also tried both high accuracy and device only modes.
Does anyone have any recommendations for how to go about fixing it? And if the best move is to flash back to stock, acquire a GPS lock, and then flash back to cm11, can anyone point me to the best method for flashing stock if I didn't back it up before flashing cm11?
Thanks!

Have you tried installing the GPS config files?
I think this will help but try download an program that will install the config files. For example I downloaded and app called Pimp my ROM and I can download the GPS files from there and it installs them for me. Do that and reboot and see if it makes GPS work.

I too had the same problem.. What i did was to copy the gps.conf file from stock rom and replaced it with what i had in ma phone with cm. This will not help much. But now i am able to get a gps lock, even though the no. of satellites locked are less compared to that detected by stock.
If you revert back to stock and flash cm, it wont help u. The files of stock will be over written by that of cm.

Update:
I tried using stock gps.conf, to no avail.
I tried flashing a different rom, and still got 0/0.
Flashed back to stock, and now have 0/26.
Think I'm going to return the phone and try to get a new one?

Did you flash a stock version .zip or the actual flashing through the LG tools? If you just flashed a .zip of stock i would just go ahead and flash with LG tools because that program wipes EVERYthing including all the phone memory we can't access.

I flashed with the official LG tool. I took the OTA to 12b and I can get a GPS lock. Maybe if I flash now it will work?

Wifi not turning on i9505 after flashing custom rom

Hello guys, after I flashed a custom rom my phone went into a bootloop. I decided to flash stock , via odin. After I flashed the stock rom for my region (open european) I got many FC messages , the phone was unusable.
I started digging and flashing roms. Now I have i9505xxugng8 which is a nordic country rom.
When I try to open wifi , the button gets green for one second but then it stays deactivated.
1. Tried to remove battery
2.Tried to delete the wpa_supplicant.conf file from /data/misc/wifi or /system/etc/wifi
3.Tried the non-hos bin.
Nothing worked. I'm desperate.

Try this steps
1. Rooted ! Open root explorer > System > Build.prop change this in the build.prop:
ro.securestorage.support=true TO ro.securestorage.support=false Save , Reboot
2. Either flash a diff kernel.
Have a nice day.

Hello repulsa, i Tried your method but it didn't work
It may be a hardware problem? But I've never dropped it

Tried hard reset?

I think you should fully wipe in the custom recovery before flashing the stock rom with Odin.

i might try this however.. im having trouble with the bluetooth and not on the wifi toggle/module. are you using the M9 build or the nightlies?

The Wi-Fi problem is knox related , I don t think switching go cm11 would solve the Bluetooth problem.
Now I'm using the latest version of miui and works well.

I also have this problem. Went from CM11 to stock (GF was supposed to use the phone and preferred stock...).
And now, no wifi, tried most things, checked build.prop, deleted wpa_supplicant, pulled battery, cleared cache.
Nothing works.
I'd be ok with going back to CM11, but the S-View cover won't work with it.
Any more ideas?

I don't think this is your problem, but just to put this out there in case other people stumble upon the thread....
This can be caused by using a custom kernel in a CM11 based ROM that was built after about August 3rd (give or take a few days)
CM changed the way the Wifi and data are managed by the kernel. So older customer kernels aren't compatible.

Booted to recovery, wiped data and cache, booted straight to Download mode, flashed stock rom, booted straight to recovery, wiped data and cache again, booted, profit.

1) Flash Wifi fix/NON-HLOS from this post. See here how to flash a modem.
2) Solved those FC / Bootloops problem flashing that KT-SGS4 Kernel.
3) See here how my same Wi-Fi / Bootlop problems were all solved.

[Q] [solved] GPS Not Working After Cyanogen Mod Install

Hi All,
I just got a new used Samsung Galaxy S4 on Sprint and brought it over to Ting (way, way, way cheaper). I got everything working with the stock ROM, including GPS, but I wanted to install Cyanogenmod, so I rooted it, flashed TWRP 7.8, and flashed the latest Cyanogenmod (snapshot M12), with Gapps, and a zip file with the Ting data XML files to get 3G and LTE working.
Everything seemed to work great, but then while driving I noticed that the GPS just did not get a lock. After trying for an hour, it still had nothing. I installed GPS Status and saw that it had no satellites. Clearing the GPS cache and re-downloading data with that app did not solve the problem. I tried GPS Doctor without success and the GPS fix equally without success.
I rebooted, then factory reset, then erased everything and flashed the latest CM nightly, all with no success.
I found some similar problems online at these places:
http://myblog-online.co.uk/2013/12/the-continuing-saga-of-my-galaxy-s4-custom-roms/
http://forum.cyanogenmod.org/topic/98811-gps-not-working-23rd-nightly/
http://forum.xda-developers.com/showthread.php?t=2172670
These are all old and none gave me anything that useful. Is it a GPS radio issue? Is there anything I can do?
I also just found this page: http://wiki.cyanogenmod.org/w/Known_Issues_page_for_d2lte, but it is for the S3, not sure what to make of it.
I made a nandroid backup of my stock rom, but then I copied it to my computer, and when I copied it back again it didn't work. TWRP failed to restore with the error "No partition selected for restore".
My plan now is to flash the stock rom with odin, confirm that GPS works there, and then try again, but this is becoming a huge time sink and I have a lot of other things to do.
Does anyone have any ideas how I can fix this? I am pretty sure it isn't a hardware issue.

That's is pretty much what you have to do. Its go back to stock and get a lock there in maps. When you have a lock just go back to recovery and flash your custom ROM of choice. That is pretty much the only fix.

Thanks ROMANTiC KiD,
Good to know that I am heading down the right path before I spend a lot of time on this.
Should I not erase everything when I flash the custom ROM? I am pretty sure last time I used TWRP advanced erase to clear everything on the phone before installing. Should I just do a regular factory reset in TWRP to install CM in order to keep GPS functionality?
Thanks!

Yes sir you can factory reset in twrp just remember to back up your files first! And you should still retain GPS lock.

Thanks for the confirmation. I did exactly that and I can confirm that it did indeed work.
Thanks so much for the help.

Hi all,
Sorry to resurrect an old thread, but I am having this issue and the stock firmware flash isn't solving the issue. It is all very odd because it doesn't actually retain any kind of lock after flashing. I'm following instruction on here, but after locking gps on stock, then going to CM I cannot get a fix. It either had a massive radius on Maps, or it just locks to my home or work location.
Since trying much more I have managed to get the occasional satellite lock via GPS Locker, but even then as soon as I move from either my house or work, it can't find anything to lock onto and just defaults to a static location.
Is there anything you would recommend? I have 2 Samsung GS4's and they both exhibit the same problem. I have also tried this on an S4 Mini, but that retained lock just fine. I'm really confused as to what to actually try. If you could recommend anything I'd be very grateful.
Again, I'm sorry to res an old thread, but no one has been replying to the one I started for this issue :/

Your problem may be that there is some new issue with the newer firmware. I had success by first flashing the *old* firmware (you can download it from my dropbox here: https://www.dropbox.com/s/o3f3ynyezyy4yw9/L720VPUFNAE_L720SPTFNAE_L720VPUFNAE_HOME.tar.md5?dl=0) and then upgrading to the second to last firmware update for the GS4: which gives you Android 5 but without fixing the MMS bug.
After that I flash TWRP with Odin, and then do a full erase in TWRP followed by flashing the latest CM. That series of steps works for me every time, although I found that large changes to my physical location (e.g. flying to England from California) cause it to break again. I actually had to sit in a cafe in an English airport with my laptop out flashing my phone back to stock just so that I could use Google maps to get to my mother's house. It was pretty ridiculous. Because of that and other issues, I now just use stock. I hate it, but I do it anyway. Good luck.
