Hi, i used SuperOneClick to root my phone and it installed 'superuser', i've tried factory resetting my phone but superuser won't go? How can I unroot my phone AND get rid of superuser? I heard something about 'sbf' whatever that means but that was on a different phone. I don't care about resetting all data etc. My phone just make it definately clear is an xperia x10... thankyou.
