view story

http://androidforums.com – ok i tried rooting my samsung galaxy prevail from Boost. With Z4root then i checked too see if it was a proper root with root checker basic. It said i dont have a proper root. My android os is 2.3.6 Gingerbread. I dont know if im doing something wrong or what. Would their be a different method or program for doing this with my phone and OS (General)
