Ok so I'm having a few issues with my Xbox 360. I received the Xbox from a friend which had a rodd, I fixed the box. Is had a modded drive in the system and after fixing the rodd I put in a game backup and verified that it was working. But the Xbox hasn't been powered on for a long time so it of course needed updates system and live. I had no problems with the system updates but when it came to the live ones I would get an error 66. So what I did was I had a few drives laying around from when I had a modded and non modded box. I took the drive from the box that was not modded threw it into the Xbox and did the live update which it worked so I shut it down and reinstalled the original drive that came with the system a modded one and now it just plays all games backups or not as a dvd. I know that the drives have keys set in them but you would think that once the originaldrive was installed it would work. So now I'm stuck without a working drive. The drive that came with it was a Samsung ts-h943 m28 and the drive I used to get past the live updates was a hitachi-lg gdr-3120l. I also have a Ben q x800474-006 drive that is flashed that's the drive that I had in my Xbox that I had years ago that I no longer have. So my question is can I get this drive working again or is it better to use one of the other drives and spoof the Xbox. Or have I really screwed my self and have to drop the nand and get the key. Thanks sorry for the long post.
