Im thinking about updating the Firmware for my xbox 360 but before I go ahead and do that I am really concerned about being banned from Xbox live. I know that if I try and log into xbox live with a changed firmware then xbox live will ban my xbox forever. But is there a way that this firmware would be deactivated when a original disk is put in? Like the NME 2.0 Chip, that I heard will deactivate itself when an original disk is put inside it. So this way you are not banned from xbox live. But suppose I put an original disk into an xbox that has the modded firmware that has not been deactivated. Xbox live will detect a change in firmware nonetheless and ban me original disk or not. What I want to do is play xbox live with the original disk that I own and just play the backups when I want to. So is there a way to turn the hacked firmware off and on via software or would I need to buy a modchip for that?
