I successfully repaired a RRoD console last night, but when I booted it I got the E64 error. I was a little worried so I searched for a solution. One person suggested that you put the hard drive in the console. I did that and it worked. I have my other premium console's HD and I tried that, but it gave me E64 again. So why can I use one HD and not the other? Is there any way to fix this?
Edit: This drive has never been flashed. It just sat unplugged for awhile during the repair process.
