Hey guys, please bare with me here. Not new to android, but new to the Xoom. I've downloaded the 3.1 update and renamed it to update.zip in Astro. How do i apply this update. Im used to HTC devices. I am NOT rooted, nor do i have any interest in rooting at this time. I tried to power down and then press power and volume down and i'm stuck at the fastbooter screen. Whats the best way to set this up? all the other threads on here seem to be for people who are already rooted, so i just want to know the best way for a device that isn't rooted. Thanks in advance!
