I was updating my 8800c to version 4.5 this evening, and my desktop apparently froze during the process. Now, my BB is blank ... the red light occasionally blinks twice. I can't get it to do anything. Battery pull doesn't help. My desktop now doesn't even recognize it in the USB port. I don't know what to do.

Follow instructions here and this should help you out.

Just hope your computer doesn't do it again.

Then follow these steps.
