I have G850EMW which I was using with V20g-IND-XX ( ANDROID 10) updated it using LG Up patched up version with firmware 40a\_00\_0627 . But for some reason it shows NT 0 error when phone boots up so I have everything but no sim network.

i have used OPEN_ESA "1","FFF,FFF,FFFFFFFF,FFFFFFFF,51" for india. but i got error in lg up: 250-1950-1 @diag port disable @0 , in lg up .

after using another version of lg up still error :current version is not available for user. can't find matched carrier. check NT-code:0

i just noticed my phone does not show s/n also.

I have already tried QFTL . But for some reason it still get stuck on factory reset blue screen with big digit 2 . So basically no network. I also tried partial boot after erasing modem\\\_s1, modem\\\_s2, op\\\_a , op\\\_b , FTM . Still same issue.

i dont have any backup of modem\_s1, modem\_s2, op\_a , op\_b , FTM . i know i ***** up but i used qfil but i dont know where it saved. cant find anywhere in laptop.
