I used a root method for my G2 (D800) that rooted the phone without the need for unlocking the bootloader.
My phone is currently rooted, locked and has the stock recovery and stock ROM. The only tweaks have been made using the Xposed G2 module.
It is the AT&T version but has been sim unlocked and is currently on T-Mobile's network.
All that said, where do I get my OTAs from ? (KK is supposedly around the corner)
Will I get it from T-Mobile? From LG?... from AT&T??
Will I even be able to receive the KK OTA at all?
All feedback is appreciated !
