Need an idiot out with GPS issues

I never had to use my GPS til now and found out it cant lock on to any GPS sat. Ive had no other issuses with this phone
This is all the things ive done. I've enable TMO AWS since day one. I'm a TMO user that was a given.
My phone had the old orginal baseband, i think its MDC, then i upgraded to MDL and now i'm on the new NB1.
Ive bounced around all KK roms and even some older roms i still had saved. Nothing can get a GPS lock. I'm leaning now towards something physical, but Google now works and they can trianglulate via cell towers.
Ive 99% sure ive enable all GPS items. Location settings are on high accuracy.
Ive been using GPS status apps to help get a better location and nothing seems to be working.
Does playing around with Kernals help? I never installed one before or played with any of those. I need GPS to be working now so if i cant figure it out soon, i might just jump ship to the nexus/s5/iphone

bump up. Anyone have suggestions?
ive tried many different roms, Touchwiz and not touch. All diffrent basebands. I dont know what kernal work with what roms so ive been avoiding that

A kernel is not going to help. Have you gone back to stock rom and still have the issue? It sounds more like it's a hardware issue. Like the gps antenna is not working.

sadly i'm thinking the same thing. It looks like a cheap part but no idea on taking it apart just yet.
I always thought a kernal acted like a driver for computers,

The kernel is the boot image and in essence it interprets between the software and hardware. If you've flashed other roms you've flashed a kernel each time.

ah, understood. I thought it was like the baseband where i had to manual change it.
Does anyone know where the GPS antenna is located at? Is it a part i can swap out or attached the main board. I just pulled apart the phone looking for obvious parts not being connected and everything looked good.
Ebay listings GPS antenna as the 3g blue cable that runs down the side of the battery. I dont think thats the GPS antenna but it does cost a small amount but i dont think that will help.

before you tear it apart try what jd suggested and odin back to stock. you may want to backup and format your internal and ext sdcards also. they can harbor old junk that may effect new roms.
also, are you wiping all including system before flashing and on your phone and some roms i believe you have to odin a modem.bin file as part of flashing. am not familiar with that stuff as i am i337 and never used odin. "yet"
not sure if any of it will help--but--
good luck

Might need more info on what our suggesting.
I'm wiping data and the option under data in clockworksmod.
I don't have anything important, everything is cloud.

I think he is suggesting that first you get the STOCK MDL Odin package and flash it. Then wipe all data, dalvich cache, and internal sdcard (remove your external sdcard before hand). Then power it up and IMMEDIATELY turn OFF WiFi, you do NOT want it to try to update on its own. Now check GPS and see if it works.
If it does work now (the FIRST LOCK can take a bit of time) Then again use casual+motochopper to root and install twrp. Then flash a good ROM. Once that is done you can check GPS again and make sure it works, it may take a bit since it will be the first lock again (I always had trouble with MK2 modem for some reason. All the rest worked perfectly).
Or just make sure you have the ROM you want to run on a external sdcard. Then remove it for safe keeping. Now go into twrp/clockworkmod and wipe data factory reset/ cache/ dalvich cache/ and sdcard. Power off the phone after it is done and reinsert your external sdcard. Do not boot up but go directly to where you have the ROM at on your external sdcard CIA twrp/clockworkmod and flash the ROM. This will give you a perfectly clean slate. Now once it is done and booted up let it sit without touching it for at least 5 minutes. Then check GPS. If it works you are good to go. Then download any of your apps from the play store (not from titanium backup in case some system setting are being reinstalled with something). Once you have your apps back check GPS again to make sure one of them hasn't caused an issue with your GPS. If all is still good use titanium backup to recover your DATA ONLY for the installed apps.

I have no idea why
I had the same problem, and I just fixed it too.. I don't know if this will cause the problem but here it goes.
I found this solution from the forum, but forgot where..
1) I installed the rom (AOSP) I wanted and checked if gps worked (but didnt work, checked with GPS Status)
2) Went to recovery, nandroid the Rom
3) Clean install to Rom that GPS worked (TW Rom) and again checked if gps worked (and worked, also checked with GPS Status)
4) While leaving the GPS toggle on, went into recovery, and without wiping anything, restored the AOSP rom
5) booted checked GPS Status and I was able to see the satellites..
I have no idea right now if this will cause any trouble.. but at least gps works in aosp..
I'll update again if I face any problems
Good luck

Its working now. Not 100% sure what the problem was but that's for everyone with the suggestions.
I flashed about 15-20 different Roms from touchwiz to aosp and miui thing.
Opened the phone up and looked for basic things not connected.
Removed my case and wireless charger insert.
Did the MDB Odin flash. With stock ROM. It didn't still didn't work.
Finally gave up and flashed back old GE ROM. And all of a sudden it works.
I think the Odin wipe and SD card wipe had a big role but not sure. Either way it works now. Might not be the fastest connection to GPS as it takes a few moments now but it works. I'm normally locked on to 13/21 SATs out there in a matter of 2-3 mins.
Now that it works I'm a little weary of trying MDL

GPS lock problems on i9505

Hi all,
I have a GT-I9505, running stock ROM I9505XXUGNG8 (KitKat 4.4.2), and I can NOT get the GPS to work. I've used GPS tester programs "GPS Test" and "GPS Status" and what I see is that the phone sees anywhere from 12-20 satellites, but does not get a fix on any of them. Once in a blue moon I'll get 1 or two to lock. I am outside or in the car when I use the tester programs, so no interference from buildings.
It is rooted, has busybox and CWM recovery on it. It does not have Yahoo Weather (just the weather app that came with the phone). I don't know if it is hardware or software at this point. It does seem to have the lovely Knox bootloader. (SE for Android status - Enforcing)
*#1234# tells me:
AP: I9505XXUGNG8
CP: I9505XXUGNG8
CSC: I9505OXAGNG8 (but I use the phone in Israel).
I've been trying to find a case that is similar to mine, but I haven't found one yet. Can anyone help me out here? I was going to re-flash the modem part of GNG8 just to see if that would help, Maybe going to CyanogenMod or reflashing the stock would help? What about GNH8? The I9505 is not sold in Israel at this time, so I have not found any Israel-specific ROM/CSCs for it. I don't know if the CSC for the I9500 (which is sold here) would help or hurt.
There are a lot of things I can think of to waste my time with, but I'm hoping some of the smart people in this forum will be able to help make it a shorter process.

Mate I've had this problem since I flashed |ROM|★GE★|►VJUGNH2◄|►41◄|.
I've tried CM11, I've tried stock for my area (UK)
I9505XXUGNG8_I9505BTUGNG2_I9505XXUGNG8_HOME.tar (stock ROM)
BL_I9505XXUGNG8_user_low_ship_MULTI_CERT (stock bootloader)
GSM_Modem_XXUGNG8_and_LTE_Modem_XXUGNG8.tar (stock LTE modem)
and to no avail. I keep having GPS lock issues. I did flash Adams Kernal when flashing the GE and CM11 ROMS. But surely flahsing stock everything should fix the bloody GPS

It looks like it may have been the GPS antenna not being connected properly when it was built. I tried SlimKat and CM11 M9 to no avail. I thought I would see if the GPS antenna was physically broken, and it looked fine. But I did hear a click when I was working with it that made me think that it wasn't attached properly. I unplugged both ends, plugged them back in, and now all 3 roms work with the GPS. So I restored my nandroid backup of the stock GNG8 and life is good. Yeah, there's Samsung bloatware, but there are enough other things in the stock rom that I think I'll just stick with it for now.
So long and thanks for all the fish,
Wayne

Well, maybe I spoke too soon? It's true that detaching and re-attaching the GPS antenna makes the GPS work again, but it only works for about a day and then goes dead again. It starts working again when I take off the back and detach/re-attach the antenna. I can't continue to constantly go through that cycle. Is it bad hardware? Do I need to find a Samsung repair shop somewhere? Or is there a software setting I'm missing somwhere?
Thanks!

Hey, just a finall wrap-up for the thread. Long story short, I eventually did a complete wipe of the phone - dalvik, cache, system, data - everything, and then did a clean installation of one of the ROMs here (Optimized CM 12.1). At that point everything snapped back to life, the GPS locks quickly, it's all the way it should be. So I guess there was something deep in the system partition that was messing it up, and it took a total wipe to clear it out properly. Happy phone user now.

[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.

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.

{Singapore} LG G3 For Singaporean User

As you guys know, MM has started rolling out to the International Model D855!
I've been on MM for 3 days and quite satisfied with the update! Rom's seems faster and snappier, no more micro lag, juice seems to be better than LP tho... What you guys think? To all Lions, Share your thoughts and comments here! Cheers All!!!

Having problem flashing MM?
Use this method:
Reboot to twrp
2. Full wipe (data, internal card, system, cache, delvik cache, format data) All zip move to external card for a clean flash
3. Flash V2 zip - robalm's thread
4. Flash boot zip - autoprime's thread
5. Flash https://mega.nz/#!gxtwVBwZ!41S8Woy2y...HhK4gcGooK7OIo permissive zip (most important part don't forget to flash this)
6. Flash betasupersu 2.52 https://mega.nz/#!F8E02RyC!XeJhx4QZH...bVd14ccRYHbNKg ( no other version worked only this version worked)
7. Flash sharpening mod 3.5 and reboot system
To me this method works 100%
I've tried on 5 of my friend's G3 and all without fail!
4G ,Titanium and ext card works flawlessly

Singaporean user here, so far it's been fantastic on stock marshmallow. With 21c modem there's no problem when it comes to connectivity (I'm on Singtel and I get 4G just like on Lollipop). Battery life much better than lollipop (average about 3.5-4h SOT compared to 2.5-3h on lollipop).
Here's a features review I did for the new stock MM

Hi oceangreen,
Saw this thread late. Black screen, Red & Blue LED flashing problem after following autoprime's thread.
Some questions:
Step 5 - autoprime didn't have this! However, your Megasync link requires decryption key? Can u provide?
Step 6 - Is this the same as autoprime's SuperSU 2.52?
Step 7 - Is this the correct link to the sharpening mod 3.5 (http://forum.xda-developers.com/lg-g3/orig-development/fix-sharpening-mod-script-1-0-beta-t2957648)? autoprime did not provide this! If I have no issues with the sharpening issue, can I skip this?
Thks in advance.

Is this still MM if use 21c modem ?

Does it have volte with sg telco

Followed the flashing guide to the letter - this V2 rom is great - but for only about 3 days.
After around the 3 day mark, the error message will flash "SIM card removed The mobile network will be unavailable until you restart with a valid SIM card inserted."
The phone will reboot within 10 seconds (even if you go to airplane mode immediately). It rebooted repeatedly first time it happened.
Did a complete nuke wipe, flashed again. Same thing - at the 3 day mark - the Singtel SIM will show the same error and reboot. After that, SIM not usable at all. All telco signals (Singtel) will be gone. No phone, SMS, let alone data of any sort.
Think it is the problem with the modem.

I have the same problem as you. except, I did not do the update and it happened out of the blue today. Been restarting my phone and if I am lucky, sometimes I get connected to the network for about an hour before the error comes on again.

Hi Matthew,
Saw your PM. Just to confirm that you have the same problem.
​Error message - "The mobile network will be unavailable until you restart with a valid SIM card inserted"
​- Bar counts up to 100% before phone reboots automatically
This is apparently a very serious problem with Android going back a few years and a few Android OS versions (KK I believe). It happens with various phone models ranging from:
LG G4
https://www.reddit.com/r/lgg4/comments/43p26p/sim_card_removed/
Nexus - Google doesn't give a F*CK
http://androidforums.com/threads/sim-card-problems.467384/
Motorola, Nexus, Samsung Galaxy etc.
https://code.google.com/p/android/issues/detail?id=66964
Google apparently doesn't give a rat's ass about it. As such it is very difficult to pin-point the problem. I have flashed & re-flashed robalm's V2 ROM at least 4 times, each time with a complete (nuke) wipe of everything including the Internal SD card. It definitely happens on the default modem (21C supposedly) that comes with it. Different modems have not helped. If you find one that works, let me know.
It cannot be a SIM card problem. Cos I've never ever taken it out since the day I got the phone. Once the problem happened, I've tried re-seating it, wiping the electrical contacts with microfibre cloth etc. Singtel shop customer service checked all the APN and network settings and confirmed it is correct, asked me to try the SIM card in other phones. Done that, nothing wrong with the SIM..
Googling further, some folks discovered that it is due to Google Apps (Play Store, Maps, G+, Gmail, Play Books/Games/Movies/Music/Services etc. etc.), which are system apps (as part of the ROM package), causing the problem after they are updated via Google Play Store. Don't we all update apps to the latest version, no?
I tried uninstalling all the updates for all of them (Settings>>Apps>>) and replacing them with the factory updates that came with the ROM. I usually freeze all the crap money sucking subscription based or in-app purchasing Google Apps that I don't use anyway. However, whether frozen or not, it still happens. Although not freezing any of them does seem more likely to cause the problem to become even more severe - like going into constant reboots as opposed to intermittent ones. When that happens, you have to go to airplane mode BEFORE the countdown completes and reboot happens. At least when it restarts, it won't hunt for the missing cellular signal and triggering another reboot. This then allows you to freeze the suckers more agressively.
It worked for a few days - I thought I had narrowed the problem down to Google Play Store, Play Framework and Play Services. But yesterday or so it has come back again with a vengeance. Freezing Google Play Store does not help by the way - besides what's the point if you can't use Play Store?
Problem is, disabling the auto-update functions on Google Play Store using:
(Play Store>>Settings>>General>>Auto-update apps>>check "Do not auto-update apps")
doesn't stop Google Play Store and Google Play services from auto-updating themselves! F*ck Google! You cannot prevent it no matter what.
Worse, everytime it auto-updates itself (or if you uninstall updates) - note that it will switch to the default setting of "Auto-update apps over Wi-Fi only" again. So you have to be fast in going to Settings in Google Play each time you reboot and open Play Store.
Some netizens have suggested ADB command line means to cripple the auto-updating. But to me that is not the freaking point. It's about trying to isolate and find the problem.
You end up uninstalling updates for Play Store several times a day but when you find that the cellular signal is gone (no bars), you realise that it has sneakily updated to 6.0.5.
But even when I uninstall all updates for Play Store. It can still happen. Maybe less frequently.
No cellular signal is bad enough. The worst aspect is the rebooting. I tried restoring my beloved KK 4.4.2 Nandroid backup but apparently I'll have to find a compatible modem again as TWRP 2.8.0 (or my previous version before upgrading to TWRP 2.8.7 for this Marshmallow) didn't manage to back it up (even though I tick everything).
Still doing trial and error to try isolating the problem. The Google apps clue seems the more likely cause, but I can't say I can discern a definite pattern yet.
It could be a bug in Marshmallow 6.0. Maybe 6.1 will solve it. Maybe its the damn Polish ROM/modem.
In the meantime, I can only say - Do not flash this ROM! Without any cellular signal, the phone is not a phone. The constantly rebooting makes it useless!

Hi Matthew,
Saw your PM. Just to confirm that you have the same problem.
​Error message - "The mobile network will be unavailable until you restart with a valid SIM card inserted"
​- Bar counts up to 100% before phone reboots automatically
This is apparently a very serious problem with Android going back a few years and a few Android OS versions (KK I believe). It happens with various phone models ranging from:
LG G4
https://www.reddit.com/r/lgg4/comments/43p26p/sim_card_removed/
Nexus - Google doesn't give a F*CK
http://androidforums.com/threads/sim-card-problems.467384/
Motorola, Nexus, Samsung Galaxy etc.
https://code.google.com/p/android/issues/detail?id=66964
Google apparently doesn't give a rat's ass about it. As such it is very difficult to pin-point the problem. I have flashed & re-flashed robalm's V2 ROM at least 4 times, each time with a complete (nuke) wipe of everything including the Internal SD card. It definitely happens on the default modem (21C supposedly) that comes with it. Different modems have not helped. If you find one that works, let me know.
It cannot be a SIM card problem. Cos I've never ever taken it out since the day I got the phone. Once the problem happened, I've tried re-seating it, wiping the electrical contacts with microfibre cloth etc. Singtel shop customer service checked all the APN and network settings and confirmed it is correct, asked me to try the SIM card in other phones. Done that, nothing wrong with the SIM..
Googling further, some folks discovered that it is due to Google Apps (Play Store, Maps, G+, Gmail, Play Books/Games/Movies/Music/Services etc. etc.), which are system apps (as part of the ROM package), causing the problem after they are updated via Google Play Store. Don't we all update apps to the latest version, no?
I tried uninstalling all the updates for all of them (Settings>>Apps>>) and replacing them with the factory updates that came with the ROM. I usually freeze all the crap money sucking subscription based or in-app purchasing Google Apps that I don't use anyway. However, whether frozen or not, it still happens. Although not freezing any of them does seem more likely to cause the problem to become even more severe - like going into constant reboots as opposed to intermittent ones. When that happens, you have to go to airplane mode BEFORE the countdown completes and reboot happens. At least when it restarts, it won't hunt for the missing cellular signal and triggering another reboot. This then allows you to freeze the suckers more agressively.
It worked for a few days - I thought I had narrowed the problem down to Google Play Store, Play Framework and Play Services. But yesterday or so it has come back again with a vengeance. Freezing Google Play Store does not help by the way - besides what's the point if you can't use Play Store?
Problem is, disabling the auto-update functions on Google Play Store using:
(Play Store>>Settings>>General>>Auto-update apps>>check "Do not auto-update apps")
doesn't stop Google Play Store and Google Play services from auto-updating themselves! F*ck Google! You cannot prevent it no matter what.
Worse, everytime it auto-updates itself (or if you uninstall updates) - note that it will switch to the default setting of "Auto-update apps over Wi-Fi only" again. So you have to be fast in going to Settings in Google Play each time you reboot and open Play Store.

Yes! correct. we have the same problem. I don't think it is a glitch on mm 6.0 because i was on lollipop 5.0 when the problem occurred and I have only flashed 5.0 roms and modems. can you try the candySiX rom and see how it fairs in your phone? CandySix Rom thread link
I tried it on my phone and was able to connect to tower until I started installing Whatsapp which cause the sucker to break and reboot. But that was in a span of 15 mins. I read that it could also be a GPS problem so I disabled GPS but the phone was still broken. From my understanding, your trail and error seems to point to the play store updating itself that causes the phone to break correct? so why not cripple it using ADB and as for the updating of apps, it be done manually through sideload. because i don't think that there will be many apps that need to be frequently updated right? and even so if we do not update the app, it does not mean that the app will lose its functionality??

Dude –punctuation please …
I wish it was that simple. I've used Android Firewall (AFSWall+) to BLOCK all internet connections for Google Play Store and Google Play Services. The sneaky bastards at Google can still somehow update the factory Google Play Store from to 6.0.5! Upon that happening, all cellular network connection WILL DEFINITELY be lost. It may or may not reboot after that.
The problem is definitely related to Google Play (Store & Services). But it is not limited to it. Even when it has not updated itself, the error message can still show up and the phone can still reboot randomly with the error message. That is why I don’t think using ADB to disable updates solves anything.
Google is definitely doing something very intrusive with their Play Store apps – (why should and) how the hell apps (even if system apps) can be allowed to affect the functions of SIM card and cellular network reception to this extent is beyond me. Big brother is really upon us.
Not keen on trying custom ROMs anymore since my S2 days. Especially when stock Marshmallow already cause so many problems. Maybe this needs to be posted in the other international LG G3 threads.

Flash tool crashed

As you guys know, MM has started rolling out to the International Model D855!
I've been on MM for 3 days and quite satisfied with the update! Rom's seems faster and snappier, no more micro lag, juice seems to be better than LP tho... What you guys think? To all Lions, Share your thoughts and comments here! Cheers All!!!

Random gps lost issues

I'm having random gps issues (since 5 months ago), I did reflash with fastboot,... nothing worked.
Any suggestions (fastboot reset the gps-device,...) would be great.

fastboot erase modemst1
fastboot erase modemst2
If rooted, setup your area with FasterGPS app, and then use GPS Status & Toolkit app to upgrade GPS Assist data.
Also make sure Location mode is set to High Accuracy (NOT device only)
If that doesn't work, probably a hardware defect.

Ialready did that, can I reflash the latest nougat modem (can't find fastboot images) ?

No... There is Nougat image.

Can you be more specific? What app are you using? This is only with Nougat Roms or with M.M. too? For some reasons Nougat don't like to fix position with GPS but still manage to get your location accurate. This make that some apps don't work properly and others do. Google maps and Here we go work perfect for me. Ndrive and a lot of gps test apps don't work ok.

I'm using icoyote and Waze. I had this issue also on MM.
I'll get a new phone from work next month, the oneplus 5.
