Hi need some help here... I was rooted running stock Froyo with a theme installed. I unrooted using z4root, did a factory reset, which worked. I downloaded the OTA and it downloads. The install fails almost immediately and I have attempted this 3 times without success. When the phone resets, it resets to Clockwork Mod Recovery. I thought the factory reset uninstalled this? Any thoughts and/or help is appreciated.
