ok i just bought an xecuter 3 solderless modchip from modchip.com, but when i went to the motherboard, the prongs on the solderless adapter are in a different oder then the ones on the one you have to solder in. I have a v1.1 xbox. i dont know if itll work with it.
Maybe you did not buy the right solderless adapter for your xbox version. Contact to modchip.com and ask them if you can exchange for the right adapter.
