I've using an Xecuter 2.0 Pro in a 1.1 Xbox ever since the chip first came out. Recently though I had to open my Xbox to fix another unrelated problem and since then the chip has stopped working. When I turn on my Xbox it just boots to the M$ Dashboard as if there was no chip at all. I reopened the Xbox to see that indeed one of the wires (the black one) had come loose. Also, when I was fixing this I knocked out the d0 wire. I have reconnected them both since but it has made no difference to the Xbox. It still boots to the original dash.
Anybody got any advice? Could it be that the wire's just appear to be fully connected and aren't?
