I've tried several times the hard factory data reset with no luck. I just want to start from scratch (actual scratch, without the SU app) and re-root.
This SU app has remained since after the ICS OTA update without the phone even having root access anymore after then.
Any links to whatever might help are greatly appreciated. I've searched a lot and can't find a solution.
P.S. I'm not very smart at the Android talk and work, but I'll do my best to figure it out.
