The only things I did (except for playing BF2) was copy FreeStyle to the onboard memory so I could load it from the dash however after doing this the xbox still seemed to operate fine as I was playing BF2 for a few hours.
Woa woa woa, lets not all get ahead of ourselves, there's the problem right there. At the moment, you shouldn't use or even touch the internal memory AT ALL. It (randomly) corrupts XBR when you mess with it (copying gamesaves, profiles, etc). So you're going to have to redo the steps of JTAG and reinstall XBR properly, but THIS TIME I suggest you zero out (read: KILL) the internal memory unit with a command from nandpro.
