That's kinda unfortunate. But I suggest you return the board if it's still feasible. If not, you can try to backup the BIOS with a BIOS flasher and flash a P1.X image instead. If it does not work, then you have to desolder the chip, flash image, and solder it back, which I had mentioned in the prior issue #1 actually.

• How to use a BIOS flasher

You can also try downgrade BIOS with AFUWINx64.EXE. Good luck.

For those who have the latest BIOS flashed already, please check FIX for boot hangs after BIOS update (ACPI PATCH)

Woaw sorry for the delay
But you should do it your self because

• ACPI part should be generated from Windows (To create kind of Map of your motherboard and devices)
• USB Map should be mapped by you (Rear but also Fron USB, also internal internal Bluetooth if you have it)
• Kext in general depend of your processor and other stuff.
• Then the config.plist is auto generated with a soft called ProperTree

You should really take a day or two to create your specific Boot.
