I have patched all my .xbe files and still I can't get it past the Xbox loading screen. It just keeps freezing

I'm not sure if this matters, but I am running Bios EVOX 2.2. And I can't reflash it because of my modchip. It is a homebrew chip and the only way to flash it I was told , is to take it out (out it has 32 wires) and flash it manually. And I have no idea how to do that.
So I hope I can still run this with my current Bios. I also have all the in game Reset switches set to OFF.
I Just want to get this working because all of you's are making me jelous with the games you are playing
