J decided yesterday to run the update and all was working spectacularly. I had everything I needed and all my apps came back. However, I was feeling good about myself and decided that I wanted to do the overclocking as well. So I flashed that part of the update, the XOOM rebooted (partially) - it never left the big red M screen. I have tried to SBF (which isn't working - the process fails before it even starts). I can get to fastboot, but once there, there isn't anything that I can do to bring the XOOM back to life. It looks like I'll be paying Verizon a visit unless some supergenius dev has a 're-animation' method that I have not yet considered. I'm currently going through very painful withdrawal symptoms and would really appeciate the help of anyone else who has been through this.
Many many thanks in advance.
