My G3 is D857 and I bought it from China. I can't find 4G LTE signal in the US. The carrier is T-mobile. I've tried both settings in the *#*#4636#*#* and 3845#*857#. Neither did work. I also tried to search the lte config.apk in the Root Explorer, but I couldn't find it. The device has been rooted. The software info is as follows:
Android 4.4.2
Baseband: MPSS.DI.3.0.c6.2-00008-M8974AAAAANAZM-1
Software version: D85710c-CUO-CN
Can anyone fix this problem? I'd appreciate it very much.
Hi there.
Are you on KK or Lollipop?
From the Modem number I suspect that you have a KK Modem/Baseband. [when I was on KK I had a 00008 modem. v20h is 00048]
If you are already on Lollipop, you ought to flash the v20h Modem which is the adequate one.
You can use Search on the Forum and get v20h.
You should then notice changes.
Thx a lot for your reply.
It's KK now.
Do u mean that the KK does not support 4G LTE on my phone?

No it probably means the phone doesnt support the frequency that T-Mobile runs its 4G network on. T-Mobile's 4G network runs on 1700 mhz and 2100mhz while the phone only supports networks running on 800/1800 and 2600 mhz
and please do not listen to the person, V20H is only for D855 variant. Please do not think flashing random things from other varians onto your phone will work.
It will result in brick and youll wont be able to do anything about it since US LG Service Centers dont repair international variants

All,
Wondering what is the general rule of thumb about flashing the international firmware(think they on M version now?) and flashing the 855 Roms? How badly will this effect my 850 At&t G3? Can I even doing it without bricking my phone?
Thanks for any opinion.

Unless said otherwise, you should never flash a ROM that was made for a different version of the one you own.
Also, chances are that it won't even let you flash it cause of the updater-script (fail safe).
Got it! So I'm pretty much stuck with waiting for AT&T to update the firmware of my phone. I'm more concerned about firmware rather than ROM's since the AT&T version is still on the 'D' version of LG's firmware and the international version already on 'N'. Would like to update the firmware ASAP to fix some bugs.

You can try the modified international stock ROM from AndroidUser00110001, you can find it here: http://forum.xda-developers.com/att-lg-g3/development/rom-poweruser-edition-v1-modified-t2930038
I'm backing up things to try it :fingers-crossed:
Hello everyone. I have a Verizon M8 (unlocked/S-off), and I have switched to AT&T.
In order for my phone to work, I loaded ARHD (great ROM, btw), as the ROM I was using while I was on VZW did not want to play nice with the AT&T SIM card.
Everything is now working except for WiFi and LTE.
Based on what I've read, LTE on AT&T ain't happening on my device due to lack of frequency band support. But the WiFi problem is likely related to firmware, and therefore (I assume), fixable.
Here's my question: is it possible after I SuperCID my phone, to install the WWE firmware to fix the WiFi problem? Or will this brick my phone?
Thanks!

If your phone is from V you should stick to Verizon firmwares and kernels. There may be exception, but as far as i know Verizon and Sprint phones have other differences from GSM variants, not only firmware and/or kernel etc. Yes, your device can be used WW, but i'm pretty sure you cannot convert to full WWE. I went so far that i used QPST configurator and RFNV manager to unlock all the bands of my phone and yet i can't get LTE to work. I do hope someone here prove me wrong, but for now i'm happy i can use my phone in eastern Europe.
Thanks for the input. I was afraid of that. So I guess I'm stuck until new VZW firmware gets released, and then maybe my WiFi will work?
I guess I could look for a ROM that is using a different base and try that.

WiFi not working could be kernel related. What kernel are you running - stock or something else. I'm using lunarkernel+viperrom.
When i read carefully, you didn't mention on what firmware you run ARHD
3.28.605.4

Well, it's the right one for the job. My guess is kernel is causing non working WiFi, but i could be wrong. Did you tried some custom kernels?
I just got my G3 and love everything about it with Cloudy rom. Maybe it could be the first time I stay with a stock based rom rather than CM. However, the call signal seems to be very weak compared to my Nexus 4 (I'm using D850 on T-mobile network)..
Is there any different baseband (or whatever you call it - radio or modem), available for this phone? I would like to try some different baseband and see if there is any differences.... I looked up the whole xda but doesn't seem to have a thread like modem collection...

Lollipop based rom. It seems that d850 is particularly poor at receiving tmobile 4g signal... It seems to be getting att one without too much problem. Is kitkat modem better? I didn't find them to be different though.
Is therr a D850 20P radio modem available somewhere??

20P is only for D855, please dont randomely flash modems that you find on the internet
Thank you for the very constructive feedback No one is randomly flashing anything, with wreckless abandon as the 855 modem is usually accompanied by a warning by actually constructive posters.
How about oosting the latest 850 modem?

Umm if you can find the KDZ or someone whos running the latest Lollpop firmware they can probably extract it for you
Well, I started this thread and I have collected Kitkat modem and the current 20F lollipop modem for D850. It seems that these two are only available. I'm trying to upload the files but xda says the files are too big. Hopefully ATT makes some new modems to solve the issue. Compared to my other devices G3's signal is almost 10 dbm poorer than others (especially same LG made nexus 4 with 33 hybrid modem...
edit: Okay here are the links for download
for kitkat

for lollipop
http://www.megafileupload.com/d90o/D850_20F_2.0.1.c1.13-00050_Modem.zip
Can anyone tell me the modem version of d850's 21q? is it the same as c1.13?

Hi. I have one of those compiled G3s with D850mainboards from Aliexpres. I cant get the GSM function running , so want to try the 850 modems. Can you refresh the modem links as mega says it is expired due inactivity? Thank you!
Hi All,
I've been reading a lot of the development post and could not fix my issue yet. Hopefully someone can help here.
I have a Rogers d852 with kitkat and rooted.
I'm trying to install a candy5 lollipop custom rom and when I do that, I cannot connect to the roger internet.... it also does not allow me to connect to 5ghz wifi until I install the lp_modem... anyways, after installing the modem, the wifi works but still no roger internet at all... even after selecting the right APN.
I also tried installing the modem and then the stock lollipop rom and it works fine....
when I put the candy5 rom on after, I lose the networks again...
What am I missing here to have custom roms other than the stock lollipop rom working with the right modem?
thanks
My info

my info cont
d854 10b (what it said when I had kitkat installed).

I have a d852 on Rogers and the rom AICP works fine with LTE. I got 2 random reboot though in less than a day. Battery life is way better than Cloudy G3 2.5.
After s second random reboot with AICP, I went back to cloudy g3 though. The wife said she called but nobody picks up the call. But I had the phone on me the whole time and no call whatsoever. So I have doubts on the rom
all good with blisspop except lte
I'm realy happy with the image I have... Blisspop 3.9.
the only problem is the LTE... but I get it is a problem on all the images based on 5.1.1 I tested... at least with this I get H+...
other than that, all works fine so far... and I tested pretty much everything I need...
can also say that battery life is 2x better than with kitkat...
again, if someone is able to help me with the lte on rogers, I appreciate.
thanks
it works now!
not sure why... but LTE works now... tested at 50mbits!
more funny is that I did not change anything...
today I when for some shopping and when I was checking the phone I notices that for the 1st time with this image it had LTE instead of H/H+.
I thought that perhaps somehow at how I had lost LTE reception... but no, for my surprise, when I got home there it was again... LTE.
Hello,
I have a Note 4 N910T that I´ve been using in Mexico with Telcel. The officially supported model here is the N910C. Anyway, I´ve been getting constant disconnections while being indoors. What´s weird is that the bars and the 4g icon always stay on, however if I try to make a call it fails. Also if I try to browse anything. After a while it will work again. If I go outside everything works.
I´m wondering if this could be a modem issue? Are there any other modems that I can flash to see if the signal improves?
Here are my specs:
N910T unlocked
Android version 5.1.1
Baseband: N910TUVU2DOK2
Currently on the N5 Express 3.4D Rom
Any help is greatly appreciated. Thanks!
