Forgive me for interjecting into this thread- but just wanted to say I was also

experiencing a similiar problem; Ice Cream Sandwich had frozen during its

install on my brand new Xoom on Day One of boot up (today.)  I used the

directions for "Soft Reset" and that unfroze everything and the update began

again- to its perfect completion!  This simple trick was a BIG help.

I bought my Xoom from an internet third party, and though it was a new unit,

it arrived with absolutely no paperwork, not even a "quick start guide" and

with a dead battery. I did get it going, and then it froze with the IMM767 update.

Then- unfroze with the help of the excellent Christina B of VZW support!

Thanks again.
