So fellas, a long time ago i've bought a Debug Kit from here and a few months ago i've tried to recover any deleted files from the HDD, what happens is that according to Xbox HDM USB the hard drive was locked, althrough it wasn't supposed to be for Debug and Devkits. I've read here in a old thread that in a case like this, the possible key would be all 32 zeroes (a null key), it turns out that it didn't work, a friend of mine tried that on an old PC he has that have the IDE ports (can't enter dos on my modern one with the IDE to USB). I couldn't unlock by using the Xbox hot swap method because it freezes on the bios when I disconnect the IDE cable from the DVD drive, not even using the Hexen dvd could get the damn EEPROM as it would also freeze too. So this ended up with me having three possibilities: 1) Try again on the friend's old pc with the unlikely to work hotswap method. 2) TSOP to get the motherboard EEPROM to get the key (and god knows why it would have a non null key). 3) If the Startup freezing issue without the dvd drive may be because of a bios, then I would have to do an XDK recovery that would wipe out again the HDD, unless if I could use a retail xbox HDD for it (which I do have).
