Hello, My xbox 360 got pushed over by my cat and the dvd drive stopped reading discs. I then bought a used xbox 360 that had RROD'd but had a working dvd drive. Then I heard that it had been flashed (or something... I don't really understand this but I bet you guys know what is done to them). I haven't had the change to even test it out yet but if I plug it in my normal xbox 360 will it work normally so that I can play my physical and real copies of games or do I have to do some changes?
