Installing Ice Cream Sandwich with root on your AU Xoom (MZ064)

The usual precautions apply. We are not responsible for any damaged devices. This procedure will wipe your data so I recommend you backup anything that is important.

Introduction
In my previous post on how to get stock Ice Cream Sandwich (ICS) installed on your Xoom, I said that root is not really needed. Well less than a few days later, I am eating my words. I found such a reason. In order to pair a PS3 controller over bluetooth with your Xoom you need to have root. I would much rather use bluetooth for that, so it was worth the effort for me.

This process will have 3 steps:

1. Install CWM Recovery so we can install the update ZIP file.
2. Install the ICS update ZIP file (already with root).
3. Install Rogue Recovery v1.3.0 to have a more up-to-date, feature-rich bootloader.

Preparation
The update does not include a custom kernel, and other than a few bug fixes, is completely stock. One nice feature is that it doesn't overwrite the recovery partition like stock ICS. If you are already running ICS, I recommend reverting to stock before proceeding. See my last post for instructions. (I would do it anyway just to be safe).

• Download the ICS update with root included here
• Download CWM Recovery from here (fastboot version)
• Download Rogue Recovery v1.3.0 from here
• Put the ICS update and the Rogue Recovery ZIP files onto a micriSD card
• Place the microSD card in your Xoom

Installation
Step 1:
Install CWM Recovery (change "recovery-solarnz-XXXXXX-XXXX.img" to the name of the file you downloaded)

adb reboot bootloader
fastboot flash recovery recovery-solarnz-XXXXXX-XXXX.img
fastboot reboot

Then once your Xoom is booted reboot into recovery

adb reboot recovery

Step 2:
Once in recovery do the following

• wipe your system cache
• wipe your Dalvik cache (under advanced)
• Install the ICS sandwich update that you downloaded to your microSD card
• Reboot

After installing, if you get an "error 7" when updating the bootloader, don't worry about it. I got the same thing. It doesn't matter because we will be updating to CWM Rogue Recovery v1.3.0 once we are done.

Step 3:
Once again when your Xoom is booted reboot into recovery

adb reboot recovery

• Install Rogue Recovery v1.3.0 ZIP file from the SDcard.
• Reboot back to recovery (under the advanced menu option)
• Do a backup if you are so inclined
• Reboot and enjoy!!
