Hello everyone, I recently installed the new Froyo version on android onto my phone, im new to this and am trying to get things figured out, I installed and it ran fine, Next time i installed i decided to use the update feature in the startup utility, it updated some files, then booted into android it brought up a screen with the time on it and the lock and volume slider, it freezes there wont let me do anything and it just reboots and puts me back into windows, could someone help me out here?
