[Help] Lg G3 randomely swithch off problem.

Hello;
My lg g3 has some strange and weird problems.
First it switch off randomely and does not switch back on normally, so i have to plug usb cable connected with charger or pc and then press power on button and then it turns on.
secondly it looses signals where as other phones have full signals at the same place with same carrier.
it was on stock 10R but then i decided to root it and install custom rom that might solve the problem, so i downgraded to 10C (since rooting 10R is bit difficult), rooted and now installing TWRP. but still problem is same.
so i think this has nothing to do with rom. Please help me to solve this issue.
Thanks

same here

LG G2 LS980/D802 touch screen working weird after upgrade to Lollipop

Hi, everyone.
I have just just purchased LG G2 LS980/D802 (I'm not sure) which was running on KitKat 4.4.2 perfectly but when I upgraded to Lollipop with a KDZ file (with LG flas too 2014) the screen started to act weirdly. After upgrading, on the very first screen I have to select language and go through all the procedure to activate my device but due to touch issue it was very difficult but I somehow managed to get through that process but the issue is still the same. As I touch an icon it touches the other area of the screen and an other app opens, the back, home, multi task buttons are also not working perfectly so I am in big trouble because I can not do anything thing with this set.
( I searched a lot on the internet and downloaded many KDZ and tot files and tried to get stock firmware(4.4.2) like
LS980ZV8_13 (tot)
LS980ZVA_01 (tot)
LS980ZVC_12 (tot)
LS980ZVE_03 (tot) and like so KDZ files also )
* the back cover says it is D802/ZNFD802
* I removed the back cover and on the inside body it is labelled as D801/D803
* I checked the IMEI on internet and one website says it LS980 and the other says it is D801
*=> After searching on the internet I found my phone is converted to D802 (I don't know why/how)
- I am badly stuck now and I don't know what to do because I do not have that much of knowledge to handle this issue.
- It is almost a weak i'm searching on the internet for the solution but I could not found any.
- I've also searched on this site a lot but could not found any appropriate solution ( so please do not refer me to other posts )
I humbly request all the experts, developers, members please help solving this problem I'm very much frustrated after a week of searching on the internet. Thank you.

Ok I am Usman Ali mobiles phone software technician. I know your issue, if you can disassemble your phone you will find that inside your phone there is different model circuit installed, it may be 801,800,ls980,vs980 etc.. so whatever you find, then download that one firmware. and flash it. i already faced and solved this issue..

I know I have an ls980 converted to d802
I bought a d802, but when I opened the back cover, I got to know that it's an ls980 converted to d802. I wanted to install cloudy g2 3.3. Should I get rom for ls980 directly, or I have to install stock ROM first. Also if I install stock ROM, will it be sim locked? Are there any risks of phone being dead, or bricked? One of the technicians out there told me that I wouldn't be able to get the correct DLL file for stock ROM. Please help. Thanks in advance.

lg g3 no service detected !

Hi everyone
i have an lg g3 d855 EU working just fine for 1 year and a half ,
And lately when i upgrade to Marshmallow and then i stated flashing a different custom roms and they all work fine!
But a week ago I got a strange problem! A sudden msg appear for few second and then phone keep rebooting:
“Mobile network will be unavailable until you restart with a valid sim card”
I’ve done a lot of research and tried them all but still the same probe:
-put a piece of paper on the top of the sim cad
-replace the sim card
- Factory reset
-flashed android 5 the original kdz file got from official lg firmware using my IMEI
-....
So I decided to get it to a technician!
-so he replaced the sim card reader with a new one! After that the phone went just fine for 4 days and then the problem come back, so I get it back to him, so he replaced the reader with second new one and he told me that the reader is not the problem and is 100% working so when I put the sim card and reboot it ask me for "pin code" but when I after put the pin code, the phone keep searching for signal for few second than it stay no service at all.
the technician sad that there is some file in lg g3 responsible for the service detection and stuff like that only be obtained from another working lg g3 and only solution is that he can get those fil from a working lg g3 and put it into my phone and he told me it will be working again for sure !
So please guys help me I’m stuck !! Is there anyone know something about these files or their names?? And if he can provide me them I’ll be so grateful. :good:

Haven't seen this problem before. A file issue? Perhaps do another complete factory reset then do a complete wipe flash of the global rom, using the LG flash tool. Get the rom here http://forum.xda-developers.com/lg-g3/general/lg-g3-android-marshmallow-discussions-t3216143
I use that rom so there shouldn't be any issues. Hope this helps

No signal or emergency calls only After upgrading or flashing ROM LG G4

Hi all,
I bought an LG G4 from Aliexpress Two months Ago, I think it's an LG G4 H815T (hong kong version) It was working perfectly until I decided to upgrade the firmware (to android 6) with LG bridge and since I made this action, I could not get signal on the phone (most of the time) and some times I get full bar signal but only emergency calls are allowed.
I tried also to downgrade to android 5 again but with no succes (I tried all possible roms and for all variants)
the strange thing is that the phone was working quite good so I'm sure that it's not a hardware problem.
Can any one please tell How can I fix that?
thanks in advance

Does any one faced the same issue before ?

Same here

I don't know if you are talking about the same issue but this occurred for me randomly. Before restart used to fix it but now nothing helps, also when I search for carrier it says your sim card can't connect to any or something like this although I have full signal bar :|

Same issue with mine

Try to restart the phone when it's connected to a power-supply or a running computer, it works for me

Same issue with
My problem is the same please help me?
thanks...

My LG G4 H818P also have the same problem.
Hope there is a solution for this.
