I have managed to stay out of trouble so far, the OTA update downloads and tries to install - then I get the error "Root suspected" during the beginning of the update process. I can just turn off and on and everything is fine. I would like KitKat, but I'm seeing so many threads saying the At&T Optimus G Pro (E980) with the 4.1.2 ROM is exempt from most of the tricks supplied here for this unit. I don't know how I managed to finally root it, I tried 5 methods then went back to the first one I tried that failed before and it worked the second time. I think it was a wrong ADB version running on my laptop.
Any tried and true methods to get KitKat for this beast and still have root? Thanks.
