a lot of mw2 games wont copy I have tried 4 copy's and not a one worked so just download it

where would i download it?

Yeah that happened on my old xenon but now I hav a trinity rgh. Either way, what I would do is either
A. try to install freestyle dash and install the games through fsd
Or B. go on pirate bay and search mw2 and find a game that's for Xbox 360. When that is done downloaded you'll notice that the game is in an ISO image, wich u can not directly run from a USB on a jtag liek that. So wut u wanna do is u download a program called wx360. Open up wx360 click file, then open, then open up the disk image. In this program it'll show u all the files, so just extract all those files from wx360 and move them into a folder called mw2 and put that on ur USB. Then ur ready to mod it up! Hope I helped

Your waiting too long,if you cant figure it out try using FSD to rip.
