So my problem is this: My retail xbox won't connect to my JTAG. What I mean is that, via system link, although the retail finds the JTAG, it just says awaiting connection 1..2..3..4 and then unable to connect to host. I have a completely clean copy of MW2 now, and this JTAG worked fine for me a few months ago. I have restored both to factory default settings, but that has done nothing. Any help is much appreciated.
