Motorola and Google made the Xoom with an unlockable boot loader (thanks for that!), so it's great news when the hacking community has a way to roll things back to stock. You never know when your experiments with Android get you so far off base that you need to return to something stable, or when you might need to prepare for any future OTA updates. That's why we're really happy to see the stock SBF file leaked out -- it allows anyone and everyone to go straight back to the software the Xoom was shipped with, using RSD lite.
We're unsure about Motorola's feelings about this one, they usually don't take kindly to their factory SBF files getting leaked, so this might not last long. You can get the download links, and a bit more information at the source link. [XDA-Developers via Android Central Forums]
