Oh wow, I was searching for why I fubar'ed my eeprom and came across this thread. It's kind of old, but it's not a finished thread. I can't believe this, but I think everybody got something wrong! This is quite odd, so please tell me if I'm completely incorrect, but I find it hard to believe that none of you (especially lordvader129) have ever been able to do this. xxSnakeEyesxx is able to unlock / lock his hdd in his 1.6 xbox. Me too! You know why? Probably because we are using ConfigMagic v1.6 FINAL. It was updated to have support for 1.6 Xboxes. I believe it also auto-converts eeprom versions for you, but I always convert it beforehand to make sure. How? LiveInfo Beta 3 was released by Yoshihiro and it has 1.6 support. I just loaded a 1.6 EEPROM, converted it to 1.1, saved the new eeprom, and exited the program. I opened up the new eeprom (the one I just converted) and it shows up as a 1.1! This is very possible, try it yourself, HERE
