i rooted my phone in froyo but verizon pushed a gingerbread update that unrooted it. I am really not in need of a root on gingerbread. system version 4.5.596 android version 2.3.3 I need to turn in the phone due to a warranty issue. How can i remove the superuser app? They will charge 299. if its on there. I just did a factory reset. How is this done?
