I used config magic and unlocked my hd, power went out in the house and now I can't boot my xbox. Ok, so I looked around all day and found some software to use on my unlocked hard drive. I backed up my hd a few days ago to dvd, copied my hdd key. I used some software called atapwd, hdunlock, hdlock. I used the key I had backed up from dvd, and then checked it again with atapwd to verify it was successfully locked. Things looked good, I was very confident at this point, but still I get the "xbox needs service screen". No error code, no nothing just the red light, and screen. anyone offer some help. PLEASE I NEED HELP!!! I do not want to have to buy another xbox, or motherboard/hdd combo. I have a lot of stuff on it. Any help at all, any would be tremendously appreciated. Thank you and sorry for the long explanation. Thank you again in advance.
