I'm not bothered about the console being banned, as it never goes on Live anyway. I'm also not too concerned about using modded firmware, stock is fine. My main priority is to simply get the Xbox working again. So with this in mind, is there anything that I can do?
I genuinely do appreciate the help so far.
You need to figure out the original drive type, put stock firmware on that drive with the key, then update to get around the E66 with your correct drive in it. You will need to figure out if its a Samsung or Hitachi drive. Depending on when it was made it can have a Samsung MS25 or MS28, or a Hitachi 46 or 47 if its a 2006 console. You need to get the key off the liteon drive and hope that is the proper one.
If this is to much hassle and you can send it in to someone who might have more drives then you to test to figure it out, buy a variety drives yourself to test or buy a new xbox
