Does it matter which model of the Optimus G I am using? And is there a backup I can make, or a revert I can flash?
I didn't see anything in that thread regarding a backup. Also, if the update is to the KK OTA bootloader, can ROMS<KK be flashed? I still run with stock occasionally and am using an LS970, so stock for us is JB 4.1.2.
