I got BlackStormX on Bit Torrent and I overwrote my xboxdash.xbe with the one in the package (note: before you think it, I'm not asking for anything illegal here, just help and advice) When I ran the dash it came up with error 21 at first, then rebooted and got 13/14. Luckily I had a backup of my xboxdash.xbe and went into Linux to restore it. I had put back in 5 of the bolts on the case when it occured to me I should check if it worked. A lot of swearing followed when I got error 16.
Error code reference here: http://www.xbox-scene.com/articles/errorcodes.php
So this means something is wrong with a file or setting to do with the dash, but the only thing I changed was overwriting the xboxdash.xbe. So I'm stuck, please help!
Oh my Xbox config before this problem:
80GB hard drive
Font exploit loading Pheonix which loaded MXM.
