Bad customer service and the included modchip was doa.
The Xbox mod works. However the same could not be said for the included open xenum modchip and Castlemania/make mhz customer service. I open a support ticket a month ago about this issue have not heard back to date. I cannot use the Xbox without the modchip because I had to replace the motherboard. The HDD is tied to the motherboard(to prove that it was indeed the modchip). This means that without a modchip the console will not boot. I do not have the HDD to the new motherboard. My console is a brick now until I get a new open xenum modchip. The console frags only when the modchip is installed. This means make mhz/Castlemania sent me a broken modchip and refuses to send me a new one. Open xenum modchips are known to be duds sometimes. On Reddit multiple users report the same issue except they get a replacement and I don't.
