OK, guys this is silly. I was in the situation you were in trying to flash with a bit of wire, and it is a terrible method.
In the end all I had to do was put a dab of solder on the end of the iron and touch the points. The pads instantly melted and the points were connected.
I've done atleast 3 version 1.1's this way and have not messed up yet. But I have also successfully flashed while holding a screwdriver on the solder points on top of the mobo. It was extremely nerve wracking, and if I had twitched in the slightest way I would have bricked my xbox.
You should reconsider using methods that might introduce more human error than is necessary. The soldering is really not that hard.
