i bought a cheap 360 off of ebay to stick in the kids bedroom and stream movies from my nas box. the package arrived, but when i tried to connect to xbox live i discovered it was banned so i can't get the media update required to play avi files. however, also included in the box was 2 spindles worth of "backup" games. turns out this console has been hacked. is there anyway i can find out which type of hack has been performed on it without having to open the case up and peer inside? and if i can find out which hack has been used, is there anyway to make it play avi files? if not, i'll just sell it back on ebay and buy another.
