So I was going to update my Phone to 4.4 KitKat.. This is a AT&T Phone. I've tried to update the phone twice through the check for updates section on the phone and both time it failed with this error message.
The phone was previously rooted and then the rooting was broken by an AT&T update so although I still get the Custom message when the phone boots up it's not rooted currently.. Do I have to roll this phone back to a unrooted version of the Firmware before I can do the update? If so can someone point me in a direction for instructions on doing that?
