^^^Wrong. It's pretty damned simple and does just about everything except modify the boot screen. I even shown joaomgcd how to do it and it was quite simple
Do you have a 32MB thumbdrive? If so, download the tool craxtion or megaXkey. Download an exploit for either Splinter Cell, MechAssault or 007 Agent Under Fire that runs Evox, and FTP into your Xbox. I suggest using the UltimateDashExploit (UDE) as you can still play LIVE with it and it's instant access to your hacked dash.
And the UDE is SO simple to install. FTP the indicated files on Drive E: and C, and copy Update.xbe from the XBL folder into the C:\ root and you're DONE!
