I have just installed the Xecuter 3 CE chip into my xbox 1.0. The flash bios screen comes up just fine. I flashed the bios, with the correct switch settings and it shutdown as it was supposed to. WHen I turned it back on, it just came up as a blank screen. I booted up backup mode and tried again, but again the same thing happened. The MS Dash still works just fine, but I can't get it booting in chip mode properly. I am using A/V cables and the soldering points seem fine. What can I do?
