Hi all, sorry eventually for my bad english
i have the lg g3 d855 16g
Yesterday i was inspired and i thought to come back to stock so i flashed the kdz 20u for my phone, after that no data signal, i can do calls but i cant get data connection, and if i force it to take 3g it says no data at all. So i thought to flash lp modem, kk modem ora try a cloudy or an aosp, none of this fixed the issue. Today i tryed flashing with .tot method but nothing change.
I have just try my sim in another phone and takes fast a good data connection, and i had put another sim in my phone and didn't work. Also configuring apn didn't change nothing.
I hope someone know something :fingers-crossed:
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.

Hi.
I got problems with signal drops every 10 sec or so.
So I tried to flash 21C, 21A and 20P modem without any luck.
Was first when I also flashed RPM/TZ my signal drop problem was solved.
But, I got a new problem.
I can't get any connection on LTE.
It's like I'm not allowed on the LTE-network, its grayed out with a !.
No problem with surf on GSM and UMTS/WCDMA.
Using TurboRom.
Do I need to try this?

Or is it some other solution?
I installed RR custom rom and now LTE works.
I guess I just needed to flash the modem a second time.
Im having this issue after flashing the stock rom, besides the phone goes off and doesn't wake up after 5 seconds standby, but i really want to focus on signal problem before fixing anything else.
imei numbers are fine (this phone has Dual Sim) i checked them after flashing but the issue is still there. the phone recognizes sim at both slots, but no signal.
I tryed to search networks and always says error while searching, so i think modem file which came with the rom isn't compatible with my carrier bands. in fact, it cant even get other bands from other carriers from my country.
i thought i might could use some files from other roms of same brand and proccessor which could recognize the bands from here, but didnt work, when i flashed them the phone didnt even recognize the sim ( and it could do it before) so i flashed previous files.
i've been looking for the really stock rom of my phone (Which is a090L, but i flashed a090) throught most of google, but i could not find anything.
if you guys know any way that at least the phone can see my bands i would be really grateful
if you need any file from the phone just request it i will upload it as fast as i can
