Lost 3G/4G signal, no internet - T-Mobile LG G2

Hello guys,
Yesterday my LG G2 from T-Mobile and also wife LG G2 from T-Mobile lost que 3G/4G icon and the internet service. Yes, both phones!
The phones can call, get sms but no internet. Already perform a factory reset, hard reset, added the right APN, tryed to change the network mode, tryed with my 3 local operators and nothing, no internet or 3G/4G signal
I'll try to return the phone to stock 4.2.2 to check if this can fix the problem, currently running 4.4.2 stock.
Any other suggestion? Maybe it's just a simple fix but coulnd't find anything.

Returned to stock android 4.2.2, using this guide: http://forum.xda-developers.com/showthread.php?t=2432476, by the Tot method and it's working again, updated to 4.4.2 via OTA and everything seems fine now :good:

No 3G on Optimus T after rooting & custom rom

Hi,
I have an LG Optimus T with T-Mobile (G509), and network data (3G/E) used to work just fine. I've unlocked the phone, rooted it using z4root, then flashed the DarkMoon rom (2.2.1, G500, based on V10c). Since that point I've lost the 3G or even Edge network data. I can only connect to the internet via Wifi. I can't even get GPS location on Maps if the Wifi is off.
Any clues? (I'm still new to Android).
Thanks a million in advance!
As I told u in a private email., I will send u a file to fix this problem, and in my next rom upgrade things will be fixed
Will this ROM work on the Optimus for Sprint??
the same thing happened to me. Can i have the file to fix this to?
I also am having the same issue with my phone. After rooting it worked fine for a couple of weeks but now I am unable to use 3G. I am only able to use data when connecting using wifi. Can you send me the file as well? I would really appreciate it. Here are my phone specs below:
LG Optimus V
Android Version 2.2.1
Baseband Version VM670ZV4_60401001
Software Version VM670ZV4
Hardware Version 1.2

[Q] Weird Issues on official Motorola 5.0.2 (brazilian)

Hello guys,
Well I have the most indescifrable issue with my Moto g (xt1032).
It was aquired with kitkat, the day 5.0.1 GPE was released I installed it, making it a xt1033 GPE.
When Motorola´s 5.0.2 was released (brazilian) I downgraded to 4.4.4, and went ahead and installed moto´s 5.0.2 for the camera..
The next day, all was going ok, wifi, gps, moblie data etc.. not a single issue.... I had made calls, sent sms, etc... but around 12:00m (lunchtime) I saw "emergency callls only".... (I have not cutted the sim card to fit in the phone).
At that time, I swapped sims, (I´m on Claro colombia, I put a Virgin Mobile Sim..) and it worked again. I could call, send messages and stuff.
But yesterday That Virgin mobile sim stopped working, Now I face the following notification: Selected network (Claro) Unavailable.
I also get another notification about Resticted mode changed.
and yet another notification that says my sim card cannot be used to register on said network.
And another notification that says cannot send mms without registering something.
And another notiication about Voice service disabled...
this is driving me crazy....
The first thing I thought was of factory resetting the phone, to no luck, as my phone gets stuck at the red exclamation android and never goes to recovery.
I tried to install Phillz recovery but I get fastboot errors.
My phone is rooted btw, bootloader unlocked.
Is this my fault? as in I did a massive screw-up, or is it the software or is it a change on the provider´s end? I dont know.
What would you recommend doing at this point?
I have entered test mode and selected GSM only, but no luck.
Please, please shine a light on me, searching for no service and specific notification content only guides me to kit kat issues, which I really don't know are applicable to lollipop.
Mercí for your attention guys, have a good night.

I had the same issue (I'm also on Claro Colombia). All you need to do is flash the official Motorola Lollipop 5.0.2 and it'll be working fine.

Thanks mate, will try and post results.
Anyway, just to know.. why does this happen?
Why is that the radio was working all right and suddenly went kaput?

nightmare trying to get CM12 to boot on 4g XT1039 - no calls but data works on stock

Hello all
I recently got a Moto G 4G XT1039 in the UK which was on the o2 network, which I've unlocked.
I want to use my Three network simcard, which works fine on stock firmware, BUT the baseband is o2's one, so with my three sim card the data works, but calls doesn't "mobile data not available" so...
Can I flash a stock standard baseband?
I've tried unlocked bootloader and installed CM12 but it get stuck in bootloop at the cm animation, so i've restored to stock... I'm oblivious what to do next?!?
Any help would be appreciated...
I just want calls to work!
Thanks in advance.
Ok i've read I need to intall cm11 first to get it to boot as cm12 just stuck in boot animation but for the life of me cant find any cm11 download links, anyone know any?
Thanks
Hi, please help, moto g xt1039 works fine on 2g calling.. but when select 3g or lte,
it doesn't connect call, always call ended automatically.. any solution please..??
Did you ever update the phone to 5.1 stock ?, if so it should work fine. If however you went straight from KitKat to CM12, that's your problem, the radio firmware needs to be updated. Links to it are in the stock image threads on this board.

Lost LTE when i enabled tethering using SQLite Editor (settings.db)

Hi,
I'am facing a big problem with my D800 LG G2
I wanted to enable tethering , so i followed instructions given here
It was a seccus enabling tehtring but when i tried to connect to LTE i was only receiving HSPAP
I did everything possible to enable LTE but in vain ( Try 2nd SIM card, Go back to JB stock Rom , make changes in Hidden menu, ..)
I think i made bad changes in Setting.db file and i can not restore original file.
Can anyone help me to restore defaut settings in this file or give me some advice to correct make change in hidden menu.
I run Stock rooted LL actually
I saw in the same thread , someone faced the same issue and resolved it by flashing T-Mobile stock Lollipop
"Flash back to kitkat and still no LTE using Simple Mobile. It must be just my phone! Guess they are not build equally!
Try everything I know how to no success and then I flash the T-Mobile stock Lollipop and LTE connected, Wow. Stupid AT&T have to remove the network type selector from us. It available to international G2 as well."
Is it safe to flash Tmobile stock ?

Weird problem when updated to 6.0.1

One week ago I got sprint model (sm-g920p) used for one week with 0 problems,i decided to update marsmhallow 6.0.1 PB6.
I wasnt getting any ota updates even ota update wasnt in settings anyway.. so i updated through odin.
Everything was ok except service connection, no service,no data,no calls nothing. Tried search manually and auto but no luck. tried gsm or lte or cdma didnt work either. Did factory reset and network reset but no luck.
It supposed to be baseband or imei problem right?
*I've checked them but imei and baseband was ok.. but no carrier.
I decided to install another roms and kernels but none of them worked either.
I am out of US zone but my phone is unlocked.
Right now I downgraded to 5.1.1 (OJ7) through odin and everything is ok right now. ( carrier service,3g,4g,lte, everything works fine.)
I am so frustrated and need help, am i missing something here?
