Motorola has started pushing official Android 4.0.3 Ice Cream Sandwich updates to users of the Motorola Xoom WiFi in the United States. That surely elated a lot of U.S. users of the Motorola Xoom WiFi. If you're living in the U.S. and you own a WiFi-only version of the Xoom, you may want to check manually for the update. If it's not yet available, you can wait a bit because Motorola is rolling out the update in phases.
But, what can you do if you own a Xoom WiFi but don't live in the U.S.? Or, what can you do if you can't wait for the official update to arrive? There's a way for you to load Android 4.0.3 on your Xoom WiFi by flashing two files to your device. The firmware is said to be “stock” Android 4.0.3 ICS, although some folks noted that this is not “stock” in the sense of “pure Google” because the firmware includes Motoblur.
A member of XDA Developers, iohyitchun, was able to grab an SBF file released by Motorola China and extracted the said file into a system.img and boot.img file, both of which can be flashed using Fastboot. Both the camera and HDMI are said to be working perfectly, and Gmail is said to sync without trouble with Contacts and Calendar.
Apparently, these files were flashed to WiFi-only versions of the Xoom, so there's no telling whether flashing these files onto the 3G or 4G versions would work. Some users of the 3G/4G version have reported success in flashing these update files, but there's no confirmation yet whether 3G/4G works.
If you want to try updating your device to Android 4.0.3 using these files, check out the rest of this article for the instructions. Follow the guide at your own risk and don't hold us responsible if you damage your device.
Congratulations! Your Motorola Xoom WiFi should now be running “stock” Android 4.0.3 Ice Cream Sandwich.
