If you have been patiently waiting for Jelly Bean to land on your GED Xoom, wait no more. You can force the upgrade by clearing the Google services framework via Settings - Apps - All - Google services framework - Clear data.
Having done this, go back to 'About Tablet' and hit the 'Check for updates' button and the latest update should appear. 4.1.1. This has worked for me today.
EDIT 24/07/2012: Confirmation that Jelly Bean is on its way for the Xoom - hopefully within the next week:
EDIT 28/06/2012: With Google's announcement of Android 4.1 'Jelly Bean' yesterday, it appears that the Xoom will receive this update some time in July. I hope this will automatically appear on my ICS Xoom, so when it does I will post an update with details on the upgrade.
I bought a Motorola Xoom last year and think it is superb. Living in the UK though I have been keen to obtain Ice Cream Sandwich (ICS) but rather disappointingly it hasn't officially been released yet. It turns out that the non-US Xooms are not officially 'Google Experience Devices' and so have some amount of customisation in their OS, making updates slower to emerge as a result. The US devices however have no such restrictions and are already able to upgrade to ICS.
The excellent Xoom forums have a good article posted on how to safely convert your Xoom to one running the stock US ROM, which you can then update to the latest release. I tried this the other day and am delighted with the results. Everything works - I still have access to the UK App Store (with prices in GBP) and the ICS experience is genuinely much slicker than Honeycomb. So, if you are impatient and wish to try this yourself, here is how I did it.
Firstly a warning:
- THIS PROCEDURE WILL WIPE YOUR XOOM AND ALL DATA ON IT - BACK-UP NOW.
- THIS PROCEDURE MAY STOP YOUR XOOM FROM WORKING PERMANENTLY.
- THIS PROCEDURE WILL MOST LIKELY VOID YOUR WARRANTY.
- FOR PRECAUTION CONNECT THE XOOM POWER SUPPLY DURING THIS PROCEDURE.
Still here? OK - I'll start with two pages for reference from which I derived this procedure:
You will need to install the Android SDK on your PC / Mac / Linux box - see elsewhere in this blog for instructions for various Linux installations, or visit this page:
Now for the procedure:
1. Connect Xoom to your computer via USB.
2. On the Xoom, go to Settings -> Applications -> Development -> Enable USB debugging - tick this.
3. Download MZ604_HWI69.zip from the Motorola Developer link above. You will need to register to access this file but this is a simple step. Unzip contents of MZ604_HWI69.zip into a folder. Move this folder into /Applications/eclipse/android-sdk-mac_x86/platform-tools/, or wherever this folder exists in your Android SDK on your hard disk. This last stage is very important you do correctly otherwise the commands below will not be able to find the ROM image files.
4. Now, open a terminal and execute the following (these examples were run on a Mac but should be the same for Linux. Windows users will need to adjust these to suit - see the Xoom Forums post for examples for Windows):
5. Check your PC is talking with the Xoom over USB with:
Which should return something like:
List of devices attached
6. Then start the procedure to flash the US ROM with:
./adb reboot bootloader
7. The Xoom reboots. When the Xoom screen shows "starting fastboot protocol support" now type in the terminal:
./fastboot oem unlock
8. Now use 'volume up / down' buttons on the Xoom to answer the displayed questions to accept the license. After some formatting, the device reboots. Now manually power off the Xoom and then, holding the 'volume down' button, power on again. You will enter fast boot again. Now in the terminal type:
./fastboot flash boot MZ604_HWI69/boot.img
./fastboot flash system MZ604_HWI69/system.img
./fastboot flash recovery MZ604_HWI69/recovery.img
./fastboot flash userdata MZ604_HWI69/userdata.img
./fastboot erase cache
./fastboot oem lock
9. Again, use the 'volume up / down' buttons to answer the questions. The Xoom now reboots into the US ROM. Once booted for the first time, start downloading all the system updates in the usual way. After 5 or 6 of these, your Xoom will eventually boot into ICS. That's it!
To return to UK version repeat the above using MZ604_H.6.2-24_Retail_Europe.zip (N.B. I have not tried this - I plan to keep my Xoom in it's GED guise and hope it receives Android Jelly Bean later this year)!
I hope this works for you. Good luck if you do try, and thanks for reading.
