Can someone please help me. So basically I buy games from this person and he sends them to me. So I got Super Mario Galaxy and the 1.9g update disc and updated. It seems to have updated fine, I get to the galaxy reboot screen and hear the voice. But when I put in Galaxy I get 'Unable to Read the Disc'. Super Mario Galaxy doesn't even come up. Then I got him to send another one which he tested and it still doesn't work even though it worked for him. I have 3.1E and don't know the problem. I've tried the 1.9g update 5 times but SMG still won't work .
