Does your USB boot successfully? If so, copy the EFI dir from the USB and paste it into the EFI partition of your HDD/SSD. That's what I had to do in order to finally get mine booting properly.

To view the EFI dir of the HDD/SSD, you need to run a couple of commands in Terminal. In terminal, type "diskutil list" to find the proper identifier for the EFI partition, and then "sudo diskutil mount disk1s1" to mount that partition - your identifier may be different. Mine was disk1s1. Once the EFI partition is mounted, just paste the EFI dir from the USB into the EFI dir of the HDD/SSD and reboot. There are a few extra things that are unneeded but it should work. Mine has been stable for months and successfully updated the OS from the App Store.
Can you share your EFI?

I eventually managed to make it work as you did say. Still, since I didn't copy the kext first time the os booted I couldn't boot anymore. What I did was to select the macos drive, hit space and select to boot with injected kexts. This way I managed to get to the desktop.

Still I have a question. On the first page it says that the BL and WIFI won't work with the default hardware. Still BL work fine. I could connect both my magic mouse and my magic keyboard. But WIFI doesn't work. Have this been fixed?

I've also added FakePCIID.kext & FakePCIID_Broadcom_WiFi.kext, but no result.

If the stock WiFi/Bluetooth card is installed, then WiFi will not work since it is not supported. You'll need to change it out with a Broadcom BCM94352Z, but make sure you're getting the correct one. There are two versions. You need the one with two slots rather than one. Before changing out the hardware, however, you'll need to make sure that you're on BIOS 2.36. If not, you'll need to downgrade since the BIOS newer than 2.36 has a whitelist that will prohibit the swap of the WiFi card. There's instructions on how to do this earlier in the thread.

Does anyone know how to disable the touchscreen or would be able to help me create a custom ssdt for usbinjectall kext?

As my screen digitizer is damaged that's why I want to disable it as it has ghost touches, preventing me from working.

When I get into the Trackpad preferences, it's blank. I have attached my debug report.

Thanks,
Jeff
