hopefully you have your eeprom saved on your PC
if not it's still not a total loss
you unlocked your xbox harddrive with config magic
so.........
you need XBOXHDM and use xbrowser to read the harddrive and find your hdd lock / unlock key
once you have that, run xboxhdm to lock it back
when you get prompted type "lockhd -p ##############################"
I know it sounds hard but really it's just time consuming
and if you are unfamiuar with all this stuff, I suggest talking to a pro in our help room
http://www.smdepot.net/irc/chat.phpthey can help you step by step
and by the way
always keep your harddrive locked for now on, your xbox needs it to be locked
if you still can't get it to work or get too frustrated to do it
ship it to SMD or me to have it done with a small labor fee.
good luck
