Why cant i hack on xbox?

Im starting to get really aggrevated because i cant find anywhere on this website that allows me to hack games in mw3 for xbox

Look, im gonna say for the amount of work, and effort, that it takes to hack the Xbox, it isn't worth the risks of hacking it. Very few people can pull off hacking it, let alone staying undetected now. Two years ago, I would have suggested doing it under someone who knew exactly what they were doing, guidance. However, if you are hellbent on jtagging your xbox, heres a guide: Here

Also, i'd suggest you start posting around more, people generally won't take the time to respond to someone who has a low post count that is looking for help. Low returns rate to put it in economic terms.
