Ok, I found a few guides on rooting the xoom but they didn't say which version of android it is, anyhow the one that I am trying to root is running jellybean 4.1.2, and it is the WI-FI only (MZ604) Plus, how do you unlock the bootloader? I also want to know how to fix it if it gets bricked, and how to fix it in a bootloop also how to unroot it in case if I need to send it back with warranty.
