@Lego, You're are always welcome. Please get started and remember to have a USB keyboard & mouse handy for the installation. Opencore did not allow my VoodooPS2Controller.kext, so we will be installing that in Library/Extensions after the installation

@Hervé, Please don't get me wrong, as I get your point and I would love to do that. The thing is that it took me more than four weeks to get where I am today and chances are that I don't remember all the things I did. Anyway let me try: 1. Create a Big Sur USB installer 2. Download the EFI-11.1.zip on post 4 above and paste it in the EFI of the Big Sur USB installer 3. For the installation phase a USB Keyboard & Mouse are required 4. After the first login install VoodooPS2Controller.kext in Library/Extensions 5. Repair permissions using Terminal or Hackintool, disconnect USB Keyboard & Mouse and reboot 6. Your Keyboard & Trackpad should now be working, just fine tune it in System Preferences under Trackpad 7. Now is the fun part of getting Read/Write Access, which there are guides on Google on how to do that 8. After done with point 7, the snapshots will be deleted and "sudo mount -uw /" working go to 9 9. Please don't deactivate the Radeon HD 8790M if you require HDMI Audio and also set to false FakePCIID_HDMI in Opencore 10. Go to System/Library/Extensions/AMD8000Controller.kext, info.plist and add 0x66061002 in both fields where the other devices are 11. Step 10 is to make your sleep/wake to be 100% 12. Always remember that after making any changes in System/Library/Extensions/ you must always "sudo kmutil install --update-all" then "sudo kcditto"

With pleasure and I wish you all the best. Please let me know once done with the installation and I will guide you further with the polishing touches EFI-11.1.zip

All is working, when I say all I mean everything. I am ready to assist anyone with the same model laptop and I will also try to help even if you've got a different one
