Hi, someone rooted my Samsung Epic 4g, it's the one that slides out and has the touch screen. I'm having issues with it and need to take it in to be tested by Sprint and it can't be rooted. Since I didn't root it I have no clue how to unroot it. Please help me, I'd appreciate it.. I know it has clockwork and some other things. I need it back to the way it was when I bought it. Factory.
