Default [Q] Any GSM rom needed

Hey there

I want to go on stock rom back but without using lg flash tool
I need a backup file. It doesnt matter from e988 or 980. It shouldn t be at&t just gsm
Can anyone upload the backup file from cwm?

I tried already this: http://forum.xda-developers.com/show....php?t=2419802

Thank you in advance
