Clockwork Recovery, also known as ClockworkMod, is a recovery console used on rooted Android Google devices, mainly using for flashing custom ROMs. It can make and restore backups, and it fairly straightforward to install too.
The root was done by coder “Koushi“, pretty much as soon as he got his copy of the device home. In a blog post, he explained how he managed to get the custom root running so quickly. He got Clockwork Recovery running by building up a recovery (which he will not release yet due to the SD slot being non-functional at the moment) via AOSP‘s kernel and then using a ROM manager to get Superuser on the Xoom. He has a short instructional on how to do the same with your own Xoom, but you will need a bootloader and adb on your computer already (Koushi has a more detailed instructional on Clockwork Recovery in a previous post).
Better get prepared for all the new custom hacks that will come out of the works from developer soon then. Let’s hope they get another OS running on the Xoom other than Android.
