Need Help regarding LG G2 LS980

Hello,

I bought a LG G2 LS980 Sprint from ebay in July 14, It was unlocked to use GSM in India. For 2-3 months it worked awesomely. But a few days ago it got shutdown on its own. I booted it and since then it does not recognize any SIM and battery drain has become very huge(over 50% overnight). I tried flight mode but battery drain is still persistent.

Even tried to get it repaired from local mobile repair but they were unable to solve either of the problem. I myself tried almost everything i can with help of xda-forum but to no use. :-(

Seeking for help here.

Thank you.

try doing a system restore and/or flashing CM11 on it. report back if that works

Flashed the original firmware 3-4 times. Also tied installing custom Roms like hellfire, Cloudy and Mahidi Rom. Both problems are persisting each time. Now i am on ZV7(4.2.2) and it does not let me flash ZV8(4.4.2)

which custom recovery are you using?

Switch to philz touch recovery and flash cm11 again

Done. But still no network coverage(although it detects SIM. shows SIM toolkit and APN's are there) and battery is draining fast(about 8-10% in half an hour without any use)

are you able to use the sim in other phones? if yes, then maybe your EFS partition has gone kaput.

SIM is working fine in other phone. I dont think its corrupt EFS, because IMEI No. is shown in About section of settings.

By the way, is there any way to be sure of that EFS is corrupted?
