My Xoom just said it was updating, so I said ok, now it is bricked and will not boot......
Ok, I did a hard reset (power and volume up) and it took longer to boot than normal but it's up and shows version 3.1 in settings/about. Hopefully this doesn't happen to other people.
FYI, it was on the standard base and charging with the Moto clock running when I got the popup for the upgrade. It shut down and green charged led was lit but it wouldn't reboot until I did the hard reset.
I'm on Wi-fi and I just got the notification. I'm taking the plunge now.
Update: I did the update. No problems rebooting, but the Xoom seems a little slower than normal. I got an update to Flash Player 10.3 last night, so I'm going to check out some Flash videos now.Wraithdroid, I see that we are in the same area and we got the update around the same time.
