Upgrade UK Xoom to Android 3.1

Print Article One of the things I hate about Android is the fragmentation of the operating system. For example, if you live in the US you will already be running Android 3.1 on the Motorola Xoom, however in the UK we are stuck on version 3.0.1. Thankfully, there is a quick, simple and legitimate method of upgrading your UK Xoom (Wi-Fi) to Android 3.1. The guide below shows you how using a Mac (running Snow Leopard).
First up, a couple of warnings: Anytime you flash a device it comes with a risk. Only attempt this procedure if you fully understand this risk and accept it. Also, ensure you backup and wipe (factory reset) your device before starting.
The Steps:
Download and Install the SDK from: http://developer.android.com/sdk/index.html.
Unzip the contents of the SDK to your "Downloads" folder.
Go into the the SDK folder "Downloads/android-sdk-mac_x86/tools/" and run "android".
Under "available packages" install "Android SDK tools", which will download a couple of files and create a folder under the SDK called "platform-tools".
Download the Wi-Fi zip file: "http://developer.motorola.com/products/software/" (the 122MB one).
Download fastboot-mac from the HTC site: http://developer.htc.com/adp.html#s2.
Unzip the contents of the Motorola Wi-Fi zip file into the Android SDK folder platform-tools "android-sdk-mac_x86/platform-tools".
Unzip the contents of the fastboot-mac into the Android SDK folder platform-tools "android-sdk-mac_x86/platform-tools".
Now open up terminal and type:
If you type "ls -l" you should be able to see "fastboot-mac", "adb" and all the "Motorola .IMG files" that you unzipped earlier.
You need to unlock your device before you can flash it. On the Xoom, enter debugging mode "Settings > Applications > Development". Connect the Xoom via USB to your Mac and type:
Now when your Xoom reboots you will see it goes into fastboot mode (it loads quickly, and stays on the same screen). Now we can run fastboot commands:
And follow the onscreen commands. It will now complete a factory reset and reboot.
Annoyingly you now need to go and set debugging mode again (Settings > Applications > Development).
Once again, reboot into fastboot:
Now you can flash using the US ROM (because the Xoom has been unlocked). Type the following commands:
./fastboot-mac flash system system.img
./fastboot-mac flash recovery recovery.img
./fastboot-mac flash flash userdata userdata.img
./fastboot-mac erase cache
Once complete, reboot the device by typing:
And that's it. Now you should have the US firmware, and after setting up your Google account you need to check for the 3.1 software update. Enjoy!
Google Android,
