Brightness glitch/hack xbox 360
So a long while ago probably like 6 months to a year my little brother decides to get in a modded lobby for whatever and he ended up getting the brightness crazy high and even turning it all the way down its still way to bright...
Since mw3 is coming out in like a month figured I would play a little mw2 but then found out brightness is jacked and I can't find any information on how to fix it.
Can anyone help me get this problem solved please?
