You know you can download Media Connect from http://www.xbox.com well, if you plug your XBOX into the PC and then put an ISO file in a folder on your PC, then get the XBOX to access the ISO file then it would start up a dashboard exploit!!
I haven't tried this yet, I dont know where to get a copy of EvoX. If this works it would be so amazing, i would be the first person to put a dashboard exploit on the XBOX 360!!!!!!!!
doubtful that it would work, and i think someones tried it already, but not sure, give it a shot, you really don't have much to lose. but i don't think media connect gives u that good of options, but maybe i'm wrong, give it a shot and find out.
