Upgrade to Jelly Bean on Xoom Without Losing Root, Recovery, or Unlocked Bootloader
Recently, the Motorola Xoom joined the exclusive list of devices that have gotten an official taste of Google’s latest and greatest. With that, the Motorola Xoom joins the Nexus 7 as the only two tablets with official Jelly Bean updates. Now, users can upgrade to official Jelly Bean without losing root, recovery, or their unlocked bootloaders.
XDA Recognized Contributor stachre, who is no stranger to this process, has posted a repackaged update that will keep the Xoom rooted with the bootloader unlocked and custom recovery. Currently, there are other options for Jelly Bean custom ROMs, but they all involve a bunch of modifications. This is just the update repackaged to include the bare essentials.
The process to install is pretty easy, as it’s basically just like installing any other ROM. Users will download the repackaged update, reboot into custom recovery, create a backup, wipe everything, and flash the ROM. This will also install the new bootloader, which will come unlocked, so users will get a message congratulating them on updating the bootloader. Thus far the only real troubleshooting issue is that some users get stuck on the Motorola splash screen after the update. Performing a factory reset in recovery fixes this most of the time and restoring a Nandroid backup should take care of it if that doesn’t work.
