I'm new with the whole modded Xbox thing, I bought one from a friend and it was great, but now it's going screwy on me. I was doing two things; adding some new skins for my UnleashX dashboard, which I don't think did anything, but then I also booted up some application and ended up selecting an "Unlock HDD" option. It was originally locked, but I changed that. I turned it on again and got the message that my Xbox needed maintenance or something and I have to call Microsoft or something. There was no Error Code, it just stayed on that screen. The green light was flashing red. I have no idea what to do. A couple other things: I DO have a plain hard drive from another computer lying around, but its not formatted for the Xbox. With that said, I DO NOT have a working computer I can connect to my Xbox. Any help would be appreciated. I can't access anything on my Xbox.
