I modded an Xbox for somebody recently and after a couple of weeks the person left the Xbox unplugged and started getting Error 16. While reading around I came upon this post: http://forums.afterdawn.com/thread_view.cfm/442879 I didnt read it carefully as the post was for a hard modded xbox. Since I didnt noticed right away, I unlocked the Hdd and of course it wouldnt boot afterwards. Looking around I found a few hdd/eeprom programs, among them LiveInfo(eeprom). I hooked up my Xbox hdd to the pc and since it was unlocked it was easy to read. I used LiveInfo, checked my Xbox hdd info, wrote down the Xbox calculated pw, which I wrote down and checked and double checked that I had the right one. I followed the instructions found here(Locking the drive): http://xbox-scene.com/articles/lock-hdd.php Since I didnt have the backup on my C: I used the calculated password to lock the Xbox hdd and it worked(I did it on DOS using HDDLock.exe) the problem is that when I hooked it back up to my Xbox now im getting Error 6. I tried unlocking it with HDDUnlock.exe and UnlockX but it wont Unlock even though Im using the same pw I used before. I even tried doing this: http://yoshi.us/forums/showthread.php?t=17443 Which worked fine but when I plug everything back I still get Error 6. Any suggestions how I should go about it? The messed up part is that I managed to fix the Xbox that was originally messed up in the first place with the Error 16 and now is mine thats messed up.
