After becoming available for the Galaxy Nexus and the Nexus S, the JRO03H Jelly Bean OTA Update for Motorola Xoom has finally arrived and is being pushed to the tablets as we speak. If you haven’t received it over-the-air yet but can’t wait to get Android 4.1.1 Jelly Bean up and running on your Motorola Xoom Wi-Fi, we’ve got you covered. Read on for details.

This update is meant only for the US variant of the Wi-Fi-only Motorola XOOM codenamed Wingray. If you have another variant, you should wait, since this one may not be compatible. Also, to be able to update to Jelly Bean using this file, you must have stock Android 4.0.4 Ice Cream Sandwich IMM76 firmware already installed. If you don’t have it already, you can easily find it with a quick Google search. If you are already on a stock ROM and have it updated to the latest version, you shouldn’t have to worry. If you have installed a custom ROM, you probably already know how to get it back to the latest stock.

Installation Guide

Ready to install Jelly Bean? Let’s get it.

Requirements:

• US Motorola XOOM Wi-Fi (codenamed Wingray) running stock Android 4.0.4 Ice Cream Sandwich
• Android 4.1.1 Jelly Bean update (Download link at the end of this post).
• USB Host (OTG) Cable (Not required for the new, updated method)
• Android SDK Installed for fastboot and adb. Alternatively, you can download standalone fastboot and adb from here. (Required only for the new, updated procedure).
• EOS Recovery R6 (Required only for the new, updated procedure)

Procedure (May not work; see UPDATED procedure below):

1. Rename the OTA file to update.zip file to a USB flash drive, or put it on a memory card and insert the card into a USB card reader.
2. Power your XOOM off.
3. Power it on again and when you see the red M logo, press and hold volume-down till you see ‘Android Recovery’ on the screen.
4. Now enter the recovery by pressing volume-up. You will see an Android image.
5. Now press power and volume-up. You should see the recovery menu.
6. Connect the USB host cable to your tablet and in its other end, insert the USB flash drive or memory card reader that has the update.zip file.
7. Select “apply update from USB drive”, followed by choosing the update.zip file.
8. The update will now start. Once it has finished, reboot your device from recovery, and you’re done.

Procedure (UPDATED):

In case the above method does not work for you, try the following:

1. Enable USB debugging on your tablet from Settings > Applications > Development.
2. Connect your tablet to your PC via USB and install the drivers if you haven’t done that already.
3. Backup all your personal data/information from your tablet to your PC. The following method will wipe your tablet clean.
4. Transfer the OTA’s zip file to your internat SD card.
5. Download the EOS recovery image from the link in the requirements section and
   • if you are using the Android SDK, place it inside your SDK’s platform-tools folder.
   • if you are using the standalone fastboot and adb, place it inside the folder where you extracted fastboot and adb.
6. Launch a command prompt window on your computer and browse to the folder location from step 2.
7. Enter the bootloader mode using the following command:

   adb reboot bootloader

8. Once the tablet has booted into bootloader/fastboot mode, you must unlock its bootloader if you haven’t already, to be able to flash the recovery. To do this, enter this command:

   fastboot oem unlock

9. Follow the on-screen instructions to accept any warning and unlock the bootloader.
10. The tablet will reboot after that. Get back into bootloader mode using the following command:

    adb reboot bootloader

11. When the tablet is in fastboot again, enter these commands:

    fastboot flash recovery eos-recovery-r6.img

12. Once the recovery has been flashed, boot into it from fastboot using the on-screen option. Alternatively, you can reboot your tablet and when you see the red M logo, press and hold volume-down till you see ‘Android Recovery’ on the screen, and select it.
13. Once inside recovery, select to install zip from sd card and choose the OTA’s zip file that you had copied to the SD card.
14. Once the installation is finished, reboot your tablet.

There you have it – enjoy running Jelly Bean on your XOOM, complete with Project Butter, Google Now, better notifications and all the other goodies brought to Android in Jelly Bean.
