did you see the android unpack animation (android in front of a trash can)? Sounds like you didn't flash correctly. The way I have suggested is to tell people to start the device, stick a paperclip in the tiny reset hole up top (forces full power off), then make sure the .zip update file is on an sd card. Put the sdcard in, hold volume up, then at the same time hold power on until you see the unpack animation. It will blank everything.
