I just got a jtag and learning how to use it. It came with MW2 and Black Ops already installed. I switched the hard drive with the one from my other xbox but I put XeX menu and the 2 other programs on there with my usb.There was MW2 in quick play but it wasn't showing up on XeX menu so I deleted it. When I go to install MW2 to XeX menu, it installs but the last couple of percent rushes and I see that MW2 did NOT install. I go to play MW2 off the disk and it says unrecognized disk status code:03-57-00. Before this, I installed CoD4 and deleted it because it wasn't working properly and the same happened. I've tried using a different hard drive,installing the game on a normal xbox then using the same hard drive on the jtag but it still says unrecognized disk.Can some tell me how to fix this!!! And also when I try to put patches on my usb to transfer to the jtag before I put it on the jtag i test it to see if it can open if .ff viewer. before I put it on the usb it opens,after I put it on the usb,right away I try to open it but it never does and it doesn't work on the jtag. PLZ HELP ME!!!
