Yesterday I was flashing a theme for the Vemon ROM on the M8. I ended up deciding I didn't like it, so I tried to go back and flash a backup I had made. However, once I flashed the backup, the device wouldn't boot up past the HTC One white screen (it will go past the HTC logo by itself, but then the One appears on the screen and stops there). I have no idea why, as I have made backups before and have had no issues. On the default backup name, it does say KOH Release keys. I don't know if that means anything. I was able to get to recovery and flash the base Venom ROM, but I'd like to know why my backups are not playing nice.
Any and all help regarding this would be appreciated.
