De-brick a Xoom :-) or unroot for 3.1 update - brought to you by the words..

....

Tonights blog post is brought to you by the words:

Brick

Fu*k

WooHoo

....

Alt. instructions: Android Central http://goo.gl/hiCVk

Original Root Steps - XDA Dev. (do not perform until this is updated for 3.1)

Alt. Rooting - 3.1 (search XDA Dev)

....

Note:

have device connected to AC charger while performing the following tasks.

I assume if you are reading this you already know how to root the Xoom [devices] and have the required OS flash utilities, etc on hand.

You will loose ALL data on the device, backup first if you still can !

This will reset to the factory (shipped OS version)

Android 3.1 update will download and prompt for install once the device is reset and rebooted

....

I will be posting 3.1 root instructions later, once I have time to review the src code, any restrictions (google/android devs) and have time to research alt solutions.

* Updated: 2:35 am May 24 2011: Several 3.1 Rooting solutions added (scroll to the end)
