Yeah, thamks already got my 360 reflashed to 1.1. Just trying to get xbox 1 games to run on it (on dvd-5). Using xdvdmulleter 10.2 to rebuild the iso to dvd-5 xtreme, but so far no luck. (360 recognizes it as a game but gets an error when trying to load, and yes I have the backwards compatability update.)
UPDATE: I gave up with it and pulled my xbox out of storage. Now I just have to make some room for the damn thing.
