TIA for taking the time to read this. I have a 360 with a samsung ms28 drive that had the xtreme5.3B firmware. I know the FW is old, but I didn't play multiplayer on XBox Live and I would just wave patch newer games to work on the old FW. Around Feb of this year, I updated my 360 with the dash update when prompted and it applied successfully. However, the 360 red-ringed shortly after reboot before I even had a chance to play any game from disc. Yesterday, I had my 360 reflowed which fixed the red ring problem. However, when I booted it up on the network, I was immediately prompted for a dashboard update. I foolishly accepted the update before investigating further. The update appeared to complete, but then a black screen popped up with E66 at the bottom. When I manually restarted the xbox, it booted into the dashboard with no error message. Then, I got prompted for the dashboard update once again (does this mean it didn't finish the update). I have not tried to run the update process again. However, now my drive will not boot any of my burned games. I put them in, and the drive just keeps trying to read the discs with an odd clicking noise, but it finally stops and does not recognize the game. I also have another drive from an old 360 that is flashed with my current 360's key. When I attach that drive, I get the E65 screen. I believe this is normal because it is not the drive that came with the system. What are the steps that I need to take to be able to play my previous games? I have my original stock firmware from the ms28 if that will help in the process. Is there a further solution that will allow me to play AP25 backups?
