What is done:
first I flash 30B bump, the problems starte. then flash 30B LGUp, flash 21a and 21c, change band in ingeneering menu, delete lteconfig, flash 30b bump with modems: 21a, 21c, 30b hybrid, change of operator, manual config APN, manual search network. All this does not help.
Any ideas?
no ideas?
Idem.
But after reboot 4G is ok, but again...every morning i lost signal 4G...only 2G/3G is ok. So..reboot & 4G is up......disappointed.
Same on my G3. I downgrade from MM to LP but problem persist.
Same here....tried rollback to kitkat stock, LP stock, CM12, Cm13, and some other roms with no luck....have just flashed stock LP for repair...
so today I tried swapping my SIM with my friend's
he is using G3 with stock 21A, and his SIM is of the same carrier as mine
after swapping, I found that my phone (and of course his phone, too) is working normally
my phone is normal even after swapping back
did some different tests like switching on and off with 3G, LTE etc., everything is normal, at least at this moment
Still working with you? So it is sim card fault? With me after searching networks everything seems to be ok, but I couldn't connect with LTE. Only sometimes successfull connection.(once a day and after reboot same...) Very strange. :/
I lost network signal randomly... i tried with 30b hybrid modem, 21a, 21c... kdz method, twrp bumped rom... and doesnt help me at all.. my network signal gets a rotating circle randomly... and in that time my phone is out of coverage... it is .... hundred times in a day... i dont know what to do, please help
same here when i use sucks 30b D855, but now everything is ok with me.
Steps that have been followed:
downgrade to lollipop 5.0
install CandySIX Rom , then try to connect to my carrier network , at the first time it not give me anything , but when i reboot my phone , LTE appears and everything fine
back to CloudyG3 2.5 then i found that the problem resolved
My phone now works well
OKAY, i found a solution to the problem and here is what i found :

Same here...
Edited: Fixed this deletings the folder LTEconfigs on System/app
Had to then configure it to auto GSM/WCDMA then switch back to LTE auto
It connected at first with 3g then it went LTE and worked normally

Some people got their phones back to normal by flashing some roms (like CM, ACIP, stock, etc.), but that didn't work for mine
not sure if it was sim card fault, but my problem solved (at that time i was back to LP stock 20h) after swapping my sim cards with my friend's.
i am still using that sim card at this moment, working fine since last thursday
Same problem here, have signal drops on MM roms with LTE connection.
Tried all methods above, nothing really helps .. ;((
The signal is fine on LP roms, tho i installed N&N so i was able to change network type to GSM/WCDMA auto, having steady signal now, but missing LTE speed, trying to find solution to fix this, but unfortunately for now.
Same, my G3 doesn't recognize my sim sometimes or it just loses signal randomly, making the smartphone almost useless.
I tried CloudyG3 2.5 Lollipop, then upgrading to Marshmallow with many radios flashed (also the hybrid one) , then I tried to come back to a stock Lollipop ROM and the signal is always unstable. I'm going crazy due to that. I'm starting to lose hope too.
I think I've tried every possible solution to the connectivity problems I've read since flashing 30b.
Freezing LteConfigs gave me more stability, but didn't solve the problem completely. Tried editing the build.prop to force LTE as preferred network type, this didn't change anything. Don't even know how many times I've changed my apn settings.
Tried every combination of modems possible: 21a/c modem with 30b rpm/tz, pure 21a/c, pure brazilian 20c, brazilian 20c with 30b rpm/tz and nothing. Changed sims multiple times, didn't work.
The only way to get a reliable connection is to limit the phone to 3G... but that isn't a solution since I pay for unlimited 4G. If I let the phone in auto mode, the instant it tries to connect I lose all connectivity and it would take up to 2 minutes searching for the network.
I'll flash the stock rom today and if it doesn't work I can safely say it should be a hardware problem.

I had exactly the same problems I tried all of the solutions mentioned modems/roms/etc but what solved it for me was flashing the Pure stock MM kdz now no signal drops or 4g problems.

Did you root after flashing the kdz? I'll try with pure 30B but having no root is almost as bad as no 4G.

No not rooted it yet, to be honest I don't like the kingroot app it looks way too suspicious to me + the rom is smooth and stable at the moment so I thought I would stick with stock for a while.

I am having pretty major issues with the wifi on my G3 D855 - When I try to connect to a network (secured or not, doesn't change anything), it instantly sets itself to 'saved (secured)'. It takes multiple tries for it to turn to 'Connecting' and then it goes back to 'Saved'. If I keep trying, it eventually shows 'Authenticating' and then 'Obtaining IP address', after which it will connect to the internet for a maximum of around 20 seconds. This renders the phone virtually useless unless on mobile data. I am currently on the stock Android 4.4.2 KitKat, but before I was on CM 12.1 Snapshot, and before that was a CM13 Nightly. The issue started around 2 weeks ago whilst still on CM13, but it had been installed for a few days beforehand, so it surely can't have been caused by it (please correct me if I'm wrong). I tried to install .zips for different modems to see if this would change anything but to no avail. Any help would be greatly appreciated.

Hi
I have a LG G4 H815, I have been running the latest Imperium Rom for 3 weeks without any issues when all of a sudden today I cannot get any network. coverage at all. I have reflashed Imperium, flashed CM13, performed several KDZ clean installs using different firmware (20D, 20G, 20H), tried flashing different modems and nothing works.
My apn settings are all correct and the phone is quite new and hasn't been dropped or anything.
I have tried my sim card in other phones and it works fine, so I think the problem lies with the handset.
I'm at a bit of a loss what to try next, if anybody can help it would be much appreciated.
Thanks
So not long ago I bought my d855. I installed a few roms and everything was cool. A few weeks ago I installed the And7.1 Ressurection remix, but when I flashed the Fulmics rom after that, the mobile data wasn't working. I tried flashing many roms including stock with the KDZ method but with no effect. Today I noticed that in the mobile data settings, changing the connection to 2G/3G instead of 2G/3G/4G it suddenly started to work. Does anyone know what's going on with the 4G connection?? I tried flashing roms, turning device on and off, and installing the correct APNs. I use mobile data basically all the time and not having 4G is a problem to me. Thanks
I've had the same problem. I've sent my phone to LG service, they changed motherboard and everything is working now.
Hey guys,
i recently clean Updated from Fulmics 2.7 to latest 7.5. Everything worked fine until i suffered from Network completely droping while Wifi is active.
I tried different scenarios. The Bug is now reproducible.
1. LTE/3G/2G Auto Mode + Wifi >> Signal loss
2. LTE/3G/2G Auto Mode without Wifi active >> Signal stays active
3. 3G/2G Auto Mode + Wifi >> Signal stays active
4. LTE/3G Auto Mode + Wifi >> Signal loss
I tried almost every Modem available for the G3 in development section(21A,21C, Those hybrid types etc.). I tried different Roms now (Cloudy, Fulmics 7.0, ZOEs).
I made a clean install of the original Firmware (V30B via LGFlashTool). Reinstalled my Backup from Fulmics 2.7
Then i tried setting different APN Settings and tried messing around with LTE Bands in the hidden Menu. But nothing worked so far.
The Issue stays over all Roms and Firmwares and Modems and Fixes i tried
I really don't know what i can do now to fix this. Maybe s.o. got a Clue or Hint what else i can try.
The LTE function is essential for me because my Provider (O2 Germany) only builds LTE Networks and 3G got less coverage here.
The only thing i can imagine is that the SIM Card or the SIM Card Holder somehow got damaged??? The Card worked proper with Fulmics 2.7 for about 2 years now. Until the Update.
Thanks in advance

No one suffers from this?
Having Ressurrection Remix installed now and it works fine. So it has something to do with the Stock LG Rom?

I was having this problem on Fulmics rom but it was not total loss of signals. It keeps on connecting and disconnecting after few seconds. Stock works fine though.
I have the same problem. Using T-mobile lg g3 d855.
Trying to resolve still...
