Okay, so I wanted to go back to the old Xbox 360 dashboard, just for the heck of it, for about a day, but I only have one Xbox 360, and I don't want to lose my data, which is on an original arcade Xbox. Could I delete the update with the hard drive removed, then keep the console offline, then when I want to play online, update with the hard drive? Or, does it not format the disk and just remove the update. Please reply! I wanna see the old dashboard again!
