GPS PROBLEM NO SATELLITE what so ever

hey guys
I recently purchased a used galaxy nexus and as soon as i got it i rooted it and headed to xda to see whats fresh.
After flashing and all that i tried to use GPS but sadly there was no satellite present so there could be no lock or anything
So I flashed another rom and still the same
So I went to stock image 4.2.2 still no satellite was found by my phone
I have look alot of places some say just turn off and turn on the location but that doesnt help either
Can you guys please help me
Right now I am running Rootool box the stable version with fancy kernal.
When i turn on gps... in the status bar it says searching for gps forever.... and the gps icon keeps on blinking.
Thank you

Have you changes Radio baseband?
If not then change it and maybe then GPS works!

GPS and radios have nothing to do with each other.
Does everything else work ok, like phone and data? Is the phone activated and have a good sim? Are you using the gps outside with a clear view of the sky? Have you waited up to 20 minutes for satellite acquisition?
If you answer yes to all the above, try downloading gps status app and use that to download new agps data. See if that works. If not, sounds like you may have a hardware issue.

I downloaded the gps status toolbox app and i did press download agps data but nothing still
anything thing else?

I'd think it's a hardware issue...

is there any other option?
if this is a hard ware problem should i talk to samsung and ask them to fix it?

Your last hope would be to restore a factory image again and see if that helps. Otherwise, Samsung would be your best bet

should i go to 4.0 build the earliest or 4.2.2?

i had similar problem (no gps) when i tried to force OTA ( i think 4.1.1?) deleting the GOOGLE SERVICES FRAMEWORK
i GOT the ota
but after it started i never catched a gps signal
tried to reset but nothing
i had to manually reinstall from fastboot ( but i was on stock at that time.... dunno if using a modded recovery is SAME thing or it leaves some file behind)
hope it works....

edit: im running ARDH latest rom, with the latest firmware. Im on ATT

I just tried downgrading my Firmware to the latest ATT version and a stock 4.4.3 att rom and still nothing.

Did you ever find out what the problem was? I'm currently facing the same issue with a different phone. I updated my bootloader and now my GPS won't lock no matter what I do (flash new rom, update AGPS with TopNTP, GPS Status, reflash old GPS, Even tried to physically fix the antennae.. nothing works)

Ok so I believe I fixed my GPS. I flashed the official Samsung stock firmware back onto my phone using ODIN and now I almost immediately get 12-13 satellites and a GPS lock. . I'm not sure you can do this with an HTC though.

Nope cant do that, I remember the odin days back with my S3 lol it would fix almost anything. I think my issue is hardware, i cracked the screen and sent it in for repair and thats how HTC returned the phone to me. with a broken GPS lol It sees the satellites but it just doesn't lock.

WIFI will not turn on

Hi guys i have a lg g3 that has been running fine on kitkat
it the received the lollipop update OTA and all went fine apart from now it wont turn the WiFi on
you can click it on and it moves to on but seems to be always trying to turn on..?? without turning on.?
any ideas..?
I have done a reset etc still no joy

Did you try to reflash? (I think that you mean by resetting that you full wiped your phone and not reflashed the rom)

Same issue here.
I get around it by forgetting network then just signing in again. Wifi works perfectly until I leave the house and return later. Then I just do the above and viola, working wifi.
I've checked with speed test app and wifi is definitely working.
Funny thing is, if I switch off wifi then turn back on it also works.
Only when ive left home and returned later does this bug arise.

Hello guys,
This thread is a little bit old, but I am curious to know if you found a workaround for this issue.
I have the same problem as the OP (not at the second poster): since I received Stock Lollipop the WiFi won't turn on. When I try to, it says "turning on" for a while then acts like it is off.
I just bought my LG G3, NCIX the reseller, refuses to refund me or replace my phone...
I performed several factory resets and tried to flash different KK stock Roms. The weird thing is that the WiFi works with KK...
Thanks for your help.

Identical experience here.
I recently got a D855 16GB, which was on stock unbranded V10a, jumped through several OTA updates through V10g, V10j, and V10k (IIRC) all with wifi working fine before getting the lollipop upgrade OTA for V20c.
Immediately wifi will not switch on - the switch itself is on, but with the off section a lighter grey compared to the bluetooth switch.
On the wifi screen itself it says "Turning Wi-Fi on..." but after a while the switch reverts to off.
It's now had OTAs to V20e and V20h, but wifi is dead on both versions.
Note that this is stock and unrooted (never rooted) so I can't believe it's something I've done. Next trick will be to root and poke around /data/misc/wifi.

Does bluetooth work or the problem is only with the wifi? I also have the same problem, wifi, bluetooth is not working and when I check in the settings the mac adress it says "unknown".

Accountability
Unfortunately this isn't a unique problem. There have been countless bad updates from multiple manufacturers. In this litigious world, I'm surprised no one has sought damages for bad updates that effect usability.

I have the same problem from yesterday. wifi and bluetooth seem to be turning on but they never turn on. i've done many factory resets but it didn't work. has someone found a solution?

^^^ Exactly the same issue. Would love a solution!
Same issue. Tried Hard and soft reset and have also updated firmware using LG Mobile Support Tool but had no success.

ok, after 24h with this problem I think I got it back to working. Let me explain what have I done:
1. Mine is a dual sim model, that I bought in hong kong by the end of 2014.
2. Yesterday, I removed sim #2 (no longer needed), without removing the battery. I had a couple of messages indicating to restart the phone, blah blah. Can't remember if I finally restarted it or not.
3. This morning I saw no wifi connection in my phone, only 3G. Tried to start wifi in the quick access menu, but this kept blinking, never starting wifi. Restarting phone... nothing. turning off bluetooth... nothing.
I figured out that the problem had to be related with the SIM as this is the last thing I had done with the phone. Thus, I tried this, with success:
4. I turned off the phone, changed sim from slot #1 to slot#2 and started the phone. Wow, it worked for some minutes, then stopped, then started again. Well, a good sign.
5. Changed again sim from slot #2 to slot #1: Wifi working again. After some time it stopped working, but soon started again. Hasn't given me more problems (after only 30 min, that's true).
Hope it helps.

HELLO
I have exactly the same problem and I think we're not the only...
D855 :
-Wifi and Bluetooth doesn't work.
-Wifi keep turning on itself and the battery drain..
-3g/4g works perfectly.
-Downgraded on kk and Wi-Fi works so it is not a hardware issue
-Even on fulmics Rom Wi-Fi and Bluetooth doesn't work
HEELP ME PLEASE

Got the same problem here. I have my G3 since november 2014 and recently I rooted it to install CM 13 on it and Xposed bcs I got tired of the laggy software of LG. One morning I woke up to drink some water and saw my phone restarting a lot of time... ok I thought its a simple bootloop. Tried to install CM again, didnt fix it. Flashed stock software and still... Bought new battery and new power flex and the problem is still there. I go into download mode, installed the software with LGs support tool and got pass the bootloop, but now wifi nor bluetooth works. I thought it's the software so I dared myself again to root it and installed TWRP and CM13, but it wouldn't boot. I installed then Liquidsmooth, based on CM13, and got it to boot up, but in the configuration menu where WiFi is needed to be added it couldn't turn on. I skiped it and in the middle of the process it started again to restart. I don't know if it's a hardware based problem or software... But I would like to try everything out before I have to buy a new phone.

I don't understand why it doesn't work because if you downgrade on kk versions your wifi & bluetooth will be back...

Have you maybe tried to change the kernel of your device? I have never done that so I am scared if I would damage something.

Here someone says it's the kernel that is having problems and installing a new one and going maybe back to the old one will fix it.

I installed CM13 and in the setup screen I actually had wifi and I could connect to my router. It was kinda strange. But bcs I have some problems beside wifi, the reboot thing, I couldn't test out if it works too. Try flashing CM13 or ROMs that are based on it like Liquidsmooth. Maybe it will help.

GPS problem after custom firmware

Hi all,
I am a little bit desperated about getting my gps on my LG g3 (D855) working again. Until last month my GPS worked just okay, something it was way off but it was workable I was on stock lollipop after the OTA upgrade from Kitkat. Because of some heating problems and huge performance problems I decided to try a custom rom to see if there was increase and it worked perfectly! I noticed that my signal reception was a little bit troubling and flash some other modems to see if it improved ended with the 20p which was okay After that i tried my gps... and it wasn't able to fix anymore when wifi is on it sees 23 gps in view (GPS Test) but all with "00" signal. When turning wifi off it went back to 9 and sometimes 0. I checked the forum offcourse and found a few solutions:
-Erase modemst1 and 2 by using fastboot, didn't work
-Kitkat stock firmware, didn't work
-Lollipop stock firmware, didn't work
-Exchanged Simcard, didn't work
-Use Top NTP other program which configures gps.conf to the right NTP server, didn't work.
-Recalibrate Compass.. calibration worked but gps doesn't
-Try turning off location service, rebooting device, turning it on.. did't work
-Trying gps only or the with google services, didn't work
-Flashed almost all available modems, all the same results, 0/23 satellites and no gps fix
-Let is tryed to find a fix for like a hour but didn't work.
-Tryed latest CM firmware and Blissrom roms but all the same results.
Do you have any solutions or ideas what might be wrong?
Thanks in advance!!
Kind regards,
Toby

Open GPS Test, press the Menu button, select Update AGPS and try again.

Dear Robogo1982, Thanks for your reply! I tried it but seems not to work i also tryed the clear function and after that the update.

Try it in Flight mode.

Tried it, even with sim removed. It also seems that gsm reception is a lot worse, could it be a mechnical problem?

Flash back to stock using KDZ

GT-P5210 : No more WiFi since wipe

dear all,
I'd like to wipe my Galaxy Tab 3 10.1 to factory settings.
I used classic startup menu (POWER+VOLUME) to access the wipe option.
When it restarts, WiFi is not working anymore : it can't activated.
It worked once, I succeeded to give the WPA2 key, I got an IP, and 2 seconds later, Wifi was not actived anymore and I wasn't able to activate it again.
I tried several workarounds, several solutions, several ODIN version to push several ROM files. Nothing is working.
Lot of ROMs are considered as invalid by different ODIN versions (even if MD5 checksum is valid).
Is there any package I can try to install (through APK inserted on the SD card for instance) to test something ?
Is there a good ROM file to download/try ?
Help...
Thank you

Try different network, if it's the same, the wifi built in is defective. There is no option other than changing a new board and it's not expensive
http://www.ebay.com/itm/121839619758?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649

Try to go back to the stock firmware to see the result.

I've already tried ROM stock
I'll bring it at my office tomorrow to check with another wlan signal
Thx for advice's

Trust me, after factory reset and at initial setting, Wifi should be turn on by default; if it doesn't your Wifi chips are defective
