So I am running an HTC One M7; I have unlocked the bootloader, rooted, and have s-off. I have tried multiple routes to revert to a pre 4.3 profile to no prevail. I have tried terminal emulator, flashing ruu's, running ruu's from a pc and I'm stuck spinning my wheels. Not sure where to go now. The phone is running 4.4.2 and 5.03.651.3. with badboyz stock kernel deoexed. Everything that I've read is telling me to downgrade the software before I can sim unlock. I need to be able to use an at&t sim with this "sprint" phone. Any help would be appreciated.
