    Looks like I am not done, after reboot, I am functional with HC 3.0. As soon as I turn on wifi and update to 3.1, it reboots and locks up on the red M again. Starting to hate that logo.

    sounds like bad images. you need to restore stock build images

    If your rooted/modified, or otherwise using a rom image, you cannot accept or install ota android build updates unless you return to stock.

    Current mz604 stock android is 4.1 jellybean (3.0 is honeycomb) (your xoom is grey, right?)

    Once you can boot up, and before you do anything else, you need to go into setttings and enable usb debugging under developer options.

    you are gonna have to try the fastboot oem unlock, and boot up, select usb debugging and restore the complete build image, then allow the ota android updates for ics and jb

    US MZ604 HWI69 build:

    see: Xoom Software Downloads

    If I were you, I would return to stock, update to 4.1 jellybean and leave it that way. Otherwise, you will end up permanently bricking this Xoom.

    OK, tried to root (it was stock before), it denied permission at "mkdir /data/media/sdcard2", I had already unlocked it. Tried reflashing the stock image again (this was my fourth try with the HW169 build) and this time the OTA update did not crash it. I am a little concerned because of the unexplained crashing and nonresponsive adb and rsd episodes but 4.1.2 has been stable for almost 12 hours now. I guess I will have to be happy that it works even though I can't say why it had problems.

    Thanks again for the help,
    Peter
