Hello,
I followed this guide to restore my sprint LG G2 to stock Kitkat 4.4.2. Everything went fine, the phone is working, the only problem I have is that I can't connect to any network. The phone is not recognizing any of the local network providers. I bought this phone on ebay and it came with a custom rooted rom installed on it, so I decided to "clean up the mess" and restored stock kitkat. As I mentioned before everything went fine, but the network is not working (it was working with the android version before i restored stock 4.4.2). Maybe its because I'm not living in the USA (I'm from Bosnia/Europe). Should I flash a different radio on it? The phone is updating atm with OTA and I'm pretty sure that the updates wont help. Did anyone else had these issues? Any help would be highly appreciated.
Update: My phone just got upgraded to Lollipop, but the network issue is still present
Update 2: I just reinstalled "cm-12.1-20151031-NIGHTLY-ls980" Lollipop 5.1.1. and it had no problems to find all the networks in my area, so this clearly has to do with stock LG android 4.4.2.
When you say you can't connect to network, are you referring to your mobile carrier network, or like WiFi?
If it's your mobile carrier that you can't connect to, you might need to switch your radio. Take a look at this guide and the section about using radio switcher: http://forum.xda-developers.com/sprint-g2/help/how-sprint-lg-g2-ls980-to-t-mobile-t3230685

Hey there. Sorry for the late response. I kinda gave up on making the stock LG ROM work, which is why I kept on using CM12.1 . What I was referring to was my mobile carrier. The phone has no problems connecting to any WiFi signal.
I didn't try to flash any radios at all after restoring the LG G2 stock ROM. Maybe I should have tried one of the radios from this CM12.1 for LG G2 tutorial. Here is a direct LINK to the full list of LG G2 radios, where I downloaded the radio for my phone. I'm not sure if the other LS980 Radios would work on my device. There are 4 different radios available for the LG G2 LS980.
Do you think flashing one of these radios would help solving this problem after restoring the LG stock ROM?

I have done stupid things in my life, but this may top them.
I purchased an used AT&T Optimus G Pro (E980) few days ago. I bought it unlocked and was using it on T-Mobile network without any problem. I live around the area where I get LTE. AND I was getting LTE. I was successful in rooting it and was in the process of installing a custom recovery when I softbricked. No problem, right?
1. I first tried to use (TOT) found at http://forum.xda-developers.com/showthread.php?t=2420219 to get back to E980 stock. I could not get past 25% no matter what.
2. I then used (KDZ) to install F240L firmware. Dumb. I know, but at the time I did not know better.
3. I then used (KDZ) again to install E988. I had signal but only 2G speed.
4. I then used (TOT) to flash E980 stock. Great, but no signal. I tried various stuffs to get the signal working. I flashed all AT&T modems found. I tried installing different custom ROMs. I tried using dial pad method. I tried modifying bulidprop, but nothing is working.
5. I have also tried flashing Taiwan KDZ, Hong Kong KDZ, Central America KDZ, Panama KDZ, and German KDZ. I also tried 3 different AT&T TOT files. I can get signal on Taiwan & Hong Kong KDZ, but no signals on others.
6. I have successfully rooted my phone using Towelroot. I have installed SuperSu, BusyBox, an GPRO Kitkat Recvery.
6. Also, when I tried to flash different recoveries, it fails. PhilZ Touch CWM fails, and my phone is being recognized as the LG F240L and does not let me install at all even though I fully flashed Taiwan KDZ file (E988). LG 240L KDZ file is the first one I flashed when the AT&T TOT failed to flash.
I have no idea what I can do to get my LTE back. If someone can give any advise to get my modem work right, I would appreciate it. I am game to flashing any fimwares or trying different roms or anything.
Thanks.
Any help or suggestion is really appreciated.

Hello, I hope you already solved your problem by the time I'm writing this, but if you haven't, here is some extras to consider.
It could be funny to think about it, but it happens to everyone, we do everything we should, and we forget the basic stuff.
For basic stuff I'm referring to going into network preferences and setting up 4G/LTE as preferred network, you may also try to scan networks and see if a 4G/LTE network is on the list for your carrier, and obviously select it, if you don't see 4G networks then there could be an issue with your modem-rom combination, try something else.
Other thing is the APN, remember to set up the proper APN, maybe your phone had the proper setup when it came to you first but you wiped it all when you started flashing roms.
There are other advanced options that I haven't used to try to set 4G as preferred networks, but since I don't have 4G with my carrier I haven't had your problems to know they are, be sure to google them or search here on XDA.
Hope this helps bro!, let us know what works for you of if you still need ideas.
Still looking

Thanks for your suggestion! I have an option to select GSM/WCDMA/LTE auto which has been selected. I have also manually entered the correct APN setting. I think I had messed up my phone when I flashed F240L firmware, but I am still looking for a way to get it start working properly again if possible.

Thanks for your help. I had already tried them all. Nothing is working.
can u tell us which model is it by removing battery and reading the label?
after doing a fresh install of "D85510l_00.kdz" that i downloaded from http://lg-firmware-rom.com/ for my IMEI now i dont have 5G at all.
i have restarted my router few times even changed the wifi name but my G3 doesnt even see the wifi name.
my old HTC ONE X see's it and can connect just fine.
so somehow i lost 5G capabilities, not sure why. can anyone help out?
thanks
checked other stock KDZ file as well, Northern Europe D85510A_00.kdz, same issue. no 5G.
so i rooted that and installed supersu and twrp and then installed rooted v20c lollipop and voila! i can see my network again.
then restored stock KDZ back (both of them), no 5G.
anyone?
Have You try KDZ from other source? or different version, i personally use 10h so far the best form me and i don't have any issues on this version, also wifi works great at 2.4 and 5 GHz, i have AC router.

well these 2 have this issue so far:
-Northern Europe D85510A_00.kdz from this post: http://forum.xda-developers.com/showthread.php?t=2785089
-D85510l_00.kdz from this website: http://lg-firmware-rom.com/
roms with no issue are rooted lollipops installed after rooting any of the first roms including:
-D855-20A-Official-skin1980
-LG_G3_D855_Stock_20C_Bumped_Fixed
i have also downloaded few stock d855 lollipop KDZ files inc:
-D85520A_00
-D85520C_00
but these have UI issues when flashed on cleaned/wiped device so i cannot check whether these works with 5G or not.
im really confused with these issues on this phone and its roms.
Hello
lte
After Installing D855 30B update on my LG G3 i can not Connect to LTE. I havent rooted it so far but i am thinking of it if it may offer any solutions other than installing CM rom. I want to keep to Stock.
Thanks
Hello. I hope you can help me resolve some issues...
I have the samsung sgh-i747m version. I originally had it rooted on stock 4.4.2 and working with a knowroaming sim. The knowroaming sim would either connect to Rogers, Telus or Bell depending on the signal strength. Mainly Bell in my case. Anyways, I use the sim for whatsapp and it was giving me issues. Namely, notifications would stop working after the phone sits for a while. I read that it might be a problem with 4.4.2 so I decided to update it to 6.0.1. Reason I chose 6.0.1 is because the guide uses the same recovery as I do (CWM) and I'm guessing that since most development has moved on to 7.1, 6.0.1 should be stable?
Anyway, I flashed the ROM and everything seems to work fine except my knowroaming sim no longer works. In other words, it doesn't connect to any network Rogers, Telus, or Bell. For some reason, when I go search for networks, it always says no networks found. So I popped in my Telus sim from my other phone and it connected to the network fine but again, searching for networks shows no networks. I think knowroaming doesn't connect because it can't find any networks either. So I spent some hours looking to see what the problem is and some of the jargon is starting to confuse me and making me hate Samsung for the things they do.
I managed to download an app called Phone Info *Samsung* and I will list the information here and maybe you can tell me what is going on:
If you have any suggestions on what I should do to get the network providers showing up, then I'm all ears. If updating to a 7.1.2 rom will fix this issue, I'll gladly do it.
Thanks.
Nobody?
Replace Cwm with twrp and try a different custom ROM?
I tried the octa-m rom 7.1.2 and still the same thing. I'm going to go back to stock and try again.
Dear all,
I got a strange situation and I've tried several options already, but I'm lost.
My LG G3 D851 (T-Mobile) is currently running on Lineoage OS 8.1 and my 4G is not working.
Even though I selected 4G preferred. Highest what I get is H+.
I've found a modem file, but that screwed up my 4G and 3G completely.
It doesnt matter which custom rom I select it will not allow me to work with 4G.
If I go back to the original Android 6 Rom I got 4G.
Who got an idea to get this fixed?
Is your IMEI still There ? Does your Phone Show Up at qpst? You did Not Read
anything i grüess so you probably havent Backes Up your efs? Ist there No Connection at all? Flashing Roms will Not fix your problem. But you should Go to Marshmallow Stock For now.
Custom Roms only Work with 21c and lower maybe you Just flashed The Wrong Modem. Google For The XDA LG G3 Modem thread

My IMEI is still tere.
Dont know what you mean with QPST.
I've got backups and I can go back to any state, but I dont know what I should even consider check the EFS?
I'll check the Modem thread.
Maybe I can find a solution in there.

The 21C thing is incorrect. Each variant of the G3 has their own set of modems. There is no 21C for the D851.
If memory serves we had 10 series (KitKat), 20 series (Lollipop), and 30 (Marshmallow). I'm currently using 30D modem from last time I had a factory stock installed. I get 4G/LTE on all of the installed ROMs (KK, LP, MM, N, O). Even when I was on 20G they were all good, though I didn't have Oreo at the time.
@Mr-Dutch, I have a small collection of D851 modems up on Mega. Since your last stock was Marshmallow I figure the ones to try, if you elect to do so, is 30D or 30E.

LG G3 D851, Mahdi v2.9 ROM (4.4.4), microG (NoGApps), MultiROM, XDA Legacy
Yeah my Bad that was for The 855. And there IT says in The Post that IT only works Up to 21c but Not sure If thats still a Thing.
So have you tried flashing a Modem? And does IT Work now?
