Help!! My XBox requires service!!

[PSonic]

I followed the directions on posted in this forum on how to properly install a new hard drive into my XBox. I have an Xectuer Lite 2.2. I made the EvoX HD install CD, swapped the drive, and then followed through with the formatting of the drive. I am able to FTP to the XBox while in EvoX with the modchip switched on. I took the next step and used ConfigMagic to lock the HD. When I switch the modchip off to go into the regular XBox dash, I get the message stating, "Your Xbox requires service. Please call Xbox Customer Support." The message is then repeated in several languages, but there is no error code associated with it.

I made the necessary backups along the way - they are on my hard drive. In my current C: drive, I have the following files:

Audio (folder)
Backup (folder)
Fonts (folder)
Skins (folder)
xboxdashdata.17f14d00 (folder)
xodash (folder)
evox.ini
msxboxdash.xbe
settings_adoc.xip
XBox Book.xtf
Xbox.xtf
xboxdash.xbe

What have I done wrong, and is it possible to fix it somehow so that I can boot into the regular Xbox dash to play Live games?

I knew I shouldn't have tried to do this myself, but I had to give it shot. Any help would be greatly appreciated.

Just to have some additional fun, I re-installed the original HD (with EvoX on it) and got the same message that I detailed above. Have I done something horribly wrong here?

PLEASE, help me.
