Hey. I managed to install by using your EFI folder. Screen was pinkish colour but I fixed it by forcing rgb. Only problem is installing xcode. It stucks saying installing. I tried other apps, they install just fine. (I also changed ROM by assigning my ethernet's mac address to it)
Edit: MacOS installer asks for internet connection. For future reference, typing "ifconfig en0 media 1000baseT" to Terminal before installing macOS, enables the ethernet. I hope this helps someone.
