[Xoom Android Development] sgtagem:
Here is a step by step guide to root your xoom that is already updated to 3.1

You might also find this useful if you relocked your device to get the 3.1 update.

****** WARNING************ WARNING************ WARNING******

1. All steps are for the 3G Verizon Wireless Xoom. The steps are almost the same for WiFi but the files you need to download are different. You can find everything for your Wifi Xoom here: http://xdaforums.com/showthread.php?t=1078019

2. You will lose all data by unlocking your device. This is just something you will need to plan for. Backup everything BEFORE you start this. If you Have any questions about backing up your data I will be happy to help. :) If you are already unlocked then you dont need to worry about this. /win

How to use this guide

.....PLEASE READ THIS!......

This guide is divided into 3 sections:

1. Root Your Xoom

2. Flash CWR

3. Flash Kernal

These sections must be completed in order. If all you want is root then just do the 1st section. If you want SD card support then you must do all 3 steps.

Each section has its respective folder in the .rar file that I’ve linked Below.

1. Root files

2. CWR files

3. Kernel

As you work your way through this guide I will refer to files located in these folders.

All files used in this guide can be found here:

1. Download the Motorola Xoom Root Zip file and unzip it.

3. adb reboot bootloader

5. fastboot oem unlock (wait for reboot)

6. adb reboot bootloader
