Flashing US 3.1 ROM on to UK wifi xoom

Flashing US 3.1 on to uk wifi xoom

Fed up of waiting for motorola to update your uk wifi xoom? Then follow these instructions on how to flash the US 3.1 ROM and receive US updates.

I have tested the images and procedure my self. But please remember things can go WRONG so


Download the images and fastboot here this only has fastboot for windows. Linux/mac fastboot can be found here

Words with the courier font are to be typed into command prompt or terminal.
Install fasboot drivers
Extract zipped images folder.
Open command prompt(cmd)
cd to the directory you extracted the files to.

Hold down power and down buttton on xoom till it says: 'starting Fastboot protocol support'
don't worry if it seems to hang on that, it's ment to.
Now you are in fastboot mode.
check you can see the device.

fastboot.exe devices

If you can not see it then you must install the drivers or configure linux, creating a udev rule depending what distro you are running.
Now lets unlock the boot loader with the following command

fastboot.exe oem unlock  follow the onscreen instructions, this will wipe everything!

Boot back into fastboot mode.
Now lets flash the US images.

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

Assuming there are no errors, thats the US 3.0.1 flashed onto the xoom.

fastboot.exe reboot

Now you should have the US 3.0.1 stock rom. so log in and check for system updates
download the 3.1 update wait for that to install.

Once the install has finished you will now have US 3.1 honeycomb on your uk wifi xoom.

If you want to stay with stock and no root then you are done and you will recieve future US updates.

That was nice and easy wasn't it? If only all android devices could be unlocked with the oem unlock command.
