My EVO 4G is unrooted and never has been. Like a lot of others I have been having problems since the GB updates. Is there a way to clear the dalvik cache with an unrooted phone, or is the only thing I can do is a factory reset? If so can someone tell me how? I also have my MSL number from Sprint. I assume having this number doesn't help at all in my quest to root being I am at 2.3.3? Thanks for any help!
