I bought a rooted ascend 2 from a buddy of mine. The phone worked great while i had it. I have since sold it on ebay, and upon arrival the new owner stated this:

"When I first turned it on, it was on the clockwork mod / CWM recovery screen. So I cleared cache and did a factory reset. When it was done, it appeared to work perfectly, so I shut it off and recorded the ESN. The next time I turned it on, it was back on that screen again and had to be reset to get it to work again."

Anybody know how to fix this, or what could be wrong?
