Motorola Xoom bricked?
I need some more details, like whether you are using stock ROM or custom ROM, stock kernel, etc. If you have ClockWorkMod, that will come in very handy. Devices do not usually brick without having root access first. If you have ClockWorkMod, restore your backup. If you don't, try and find your stock ROM from the Internet, although when you carry out the second method, you will lose all data on your phone (not SD card though, if it's one you plugged in manually to expand the memory).

Kind Regards,
