Please Help! My Phone Doesn't Get Any Signal - AT&T LG G3

My brother bought a G3 d850 for me two days ago. The phone works very fine on 2g but when I switch to WCDMA only,the signal completely goes out.
I have tried factory reset many times and even flashed cloudy 2.5 rom but the problem still persists. Flashing stock modem didn't help either.
Please someone help me because the phone is currently useless to me without 3g.

Boost Moto G flashed to Page Plus no 3g

Hello. I flashed my phone following these instructions. http://forum.xda-developers.com/showthread.php?t=2681166 Everything works great except for data. I have tried the stock verizon rom 4.3 and 4.4.2 with no success. I have tried Cyanogenmod with no luck as well. I am stuck with 1x. I have tried resetting my esn. I have reflashed the rom onto the phone 3 times. Reprogrammed OTA countless times and still can not get 3g to work. I have done some digging and have yet to come up with a solution. I need a direction to go on this. I have attached my screen shots of DFS tools. Thank you for your help!
Interestingly enough I can get it to now show that there is 3g but only when I am connected to my wireless home network. As soon as I disconnect it then it reverts back to 1x.
Fixed.....
I am not sure exactly why this didn't work before. Retried installing 4.3 and did my changes again in DFS. Rebooted my phone and everything is working great. Verified procedure with second moto g.
I am having the exact same issue. How did you fix it?

[Completed] Signal Loss

I've been searching high and low for a fix to my occasional data loss problem. When signal is lost (0 bars) sometimes it won't come back until I restart the phone or put it in and out of airplane mode.
My problem started when I upgraded to Virgin Rom GPE 4.4.4. While on 4.3 everything worked fine. But now when I revert back to 4.3 I'm faced with the same signal loss issue. I flashed the modem from http://forum.xda-developers.com/show....php?t=2544612 and still no luck.
I've also flashed Danvdh version of GPE 4.4.4 and I face the same issue.
Any help would be appreciated.

[Q] APN Problems

Hi everybody!
A friend of mine has a huge problem with data connection.
First of all he has all stock with the last ITALIAN ROM, and when we bought it 2 years ago the phone worked well. The phone is branded "VODAFONE ITA" but in the beginning no problems with it, and he is TIM. He hasn't recharge his credit on the sim for a while and now the data connection doesn't work neither if i put the APN's manually.
It seems that nothing can solve the problem, i tried a restore, to install a stock rom but nothing.
Can anyone help me?
Thank you very much! :fingers-crossed::fingers-crossed:

No signal issue (maybe wrong baseband?)

Hi guys, I get a mate 7 bought on amazon warehouse deals!
It detects signal after 10 minutes and let me send a couple of sms... but after a pair of minutes it starts to lose signal again for about 5 minutes... So where is the problem? Sims are working on other phone, I wipe everything 3 times, but still haven't a solution... Please tell me there is something I'm missing, I don't want to send it back....
try 2g or 3g/2g mode of network, I had similar issue with KitKat 4g enabled, it wasnt so on Lollipop with 4g. Well, now my phone doesnt see sim card at all and after trying to return to KitKat I've got a soft brick, so, be careful

Thank you, I have tried, it's not working... I have tried 3 different carrier, nothing change...
What about baseband? Maybe someone flash a wrong baseband: how can I check if I've installed the right version?

That I also wonder.
Are there any Huawei gurus out there? I'm new to Huawei from Samsung.

[Completed] htc M8 only 1x after reset

Hello, having some troubles with data. Phone calls and text work fine. I have an HTC one m8, viperone rom, on PPC. A few nights ago I let my battery completely drain to the point that it would get stuck on boot screen. So I did a factory reset, that got me out of the bootloop but since then I only have data when im on 1x, nor 3g or 4g, says mobile data disconnected. I have been using roms for a few years, no expert but i know enough to check the basic when troubleshooting. So next i tried installing a new sim card, same issue. Next I flashed the same 5.1 rom, same issue. I downloaded the latest rom from viper, 6.1 installed fine but now no data at all. So tried all the reboots, reinserted the card, airplane mode, modes, etc.....
Do i need to install a new radio firmware? I currently have the 1.12
Or did I mess up the divice with the battery completely draining?
Hopefully its a noob error I can fix with some advice from you guru's
Much thanks in advance!!
Bill
