LG G2 LS980 Touch pad and Sim Card not Working After Updating

Yesterday I bought LG G2 D802 (32gb) from market I checked it in Hardware information it was exactly D802 and also install cpu z it also showed same model. So, I update with D802 lollipop firmware using LG Flash Tool. After updating its touch sensor working randomly in the meanwhile sim card is also not detecting. It also lost imei number
I download many firmware but in vain. However, when i removed its back cover i was shocked to see it was LS980.
Now prob is that D802 firmware is not working properly as i told you touch sensor and signal issue. I'm also unable to update it in LS980 firmware because it gives error that wrong model and cannot update it.
Pleasssse anyone help me out.....

Bad signals at end of f240L kdz flash

my phone was AT&T g pro that is E980 with an android version 4.4.1 and i updated it to 5.0 with a kdz of 240L that is U+
at the end of the CES flashing (done of flash and installation of apps) i realized that my network signal is down that means no bar of a net signal but always searching for networking .so with this problem i decided to return to my old AT&T operating system ,in which i still faced the same network problem that i had after CES flashing of the kdz file. but before U+ i was having full network .please any help
bro.... i did the exact same thing u did. what i read in several other post was some people figured to solve the problem by flashing our g pro e980 with the mexico telcel e980 kdz to get the signal fixed then flashed the g pro e980 att TOT image. i tried but no success with my phone. give it a try, i hope ur phone gets fixed.

Check your IMEI. Probably corrupted EFS partitions... I really hope you have a EFS backup.

Lg g4 h815 .No service. Need help pls
I am from india. I recieved an international version lg g4 h815. Software version H81510h. I upgraded to H81520L MM using LGUP. After that I'm not getting network. The mobile network option in settings is inaccessible and not highlighted. The phone works perfectly appart from that. I tried searching the issue. I guess it has something to do with the change in modem after update.
Its a case of very low signal reception. I can get 50% signal where it used to be 100. And no network where i used to get 50% network. Anyone solved this issue?
Check your imei i suspect that your modemst is corrupted..
