Ok, I fould a 4 pin section of an old pin header. So with that and the 12 pin header I have I soldered them onto my brand new version 6 or what ever xbox, thats the one where I had to use the part to re build the tracks!
That all went great put it back together and tryed it, and again it didnt boot propperly

It flashesh green and then turns orange and turns off a couple times and then turns off compleatly, the modchip also flashes, but only when I have the external switches pulged in. With out them it just does nothing, I have tryed it with the modchip enabled and disabled and the same thing.
If I unplug it then xbox starts up fine
Is this a bad solder point, or do I need to get another modchip? Bearing in mind this is the same one that I put in the old box which died on me? Thanks again...
Hope I can sort this out soon!
