I recently installed android firmware 4.0.3 onto my samsung galaxy s2x (from telus model SGH T989D). and its not running the way i want it to. i want to restore firmware 2.3.5 back onto it, but i dont know how. i tried the factory reset but i still get 4.0.3 on the phone. i keep trying to search online but its so confusing. is there an easy way to restore its original firmware? please help!!!
