Installing Ice Cream Sandwich (Android 4.0.3) on your AU Xoom (MZ604)

Posted by Unknown
As with anything the usual precautions apply. We are not responsible if you damage your device. This will wipe all of your data so backup your data if you need it. This process will first install US Xoom WIFI Honeycomb firmware, which will then allow you to get an OTA update to the official Ice Cream Sandwich Android 4.0.3 update (IML77).

Now that ICS adds the ability to take screenshots (hold volume down + power for 3 seconds), there is less or a reason to have root privilege, especially since it removes the necessary DRM keys for watching rental videos from the Market.
  1. Preparation
    • First, go to the Motorola Developer site and download the image for the US Xoom WIFI MZ604.
    • Extract the ZIP file and place them in the folder containing the Android developer tools.
    • Connect your Xoom to your PC and enable "USB debuging" under settings -> applications -> development -> "USB Debugging"
  2. Unlock your bootloader if you have not done so already:

    adb reboot bootloader
    fastboot oem unlock
    adb reboot bootloader

  3. Flash the US WIFI Xoom firmware:

    fastboot flash boot boot.img
    fastboot flash system system.img
    fastboot flash recovery recovery.img
    fastboot flash userdata userdata.img
    fastboot erase cache
    fastboot erase userdata
    fastboot reboot

  4. Lastly configure your Xoom and then install the series of over the air updates. The very last one should be Ice Cream Sandwich!

    In the early honeycomb builds it checks on a schedule and then after the first couple updates you should be able to force it to check. But I imagine by now it already checked and found the update.
