You guys are all quite wrong, in my opinion. First of all, ConfigMagic COULDN'T HAVE changed the EEPROM. The Jumpers to flash the TSOP weren't soldered, so you can't change the EEPROM. If you could, what would be the point of soldering it?
Follow my tutorial posted on this board. You CAN fix it without a modchip or TSOP flash (not that you could, anyhow). The tutorial is at
http://forums.xbox-s...T&f=41&t=105803 if you need guidance to lock/unlock the drives.
Error 6 is a 'cannot load dash' error, not 'hacked bios'.
Here's what you do.
You have that backup on a cd-r, no? Use the key in hddkey.txt (without colons or 0's) to unlock the original HD (using hdunlock.exe, in dos). Also use hddisabl with the same key. You can also unlock the 120 gigger using your friend's key. Grab his backup folder, use liveinfo - click 'load eeprom' and point it to eeprom.bin off HIS BACKUP. It should give you a 40-character key in the bottom half of the screen. You can use this to unlock the 120 gigger. If that doesn't work, try the key in hddkey.txt (from HIS backup folder). He may have been dumb and used that. Remember to use hddisabl after you unlock.
If you can get either of them unlocked, you are good to go. You can lock both drives with hdlock.exe . Use the key in YOUR hddkey.txt to lock the original HD - use the key given to you from liveinfo when loading YOUR eeprom.bin to lock the 120 gigger.
Good luck with it, PM me if you have further troubles.
