I've been cranking on this for a few days now, with no luck. I have the exact same model as innocentrose

Is your model S7 16ARHA7? Here is a reference EFI. But I have tried it never works. You can also upload your own created EFI and the error message. I think people here are happy to assist you.

Any success story on recent update?

Some AMD laptop owners had to resort to using GenericUSBXHCI.kext to fix not being able to use their USB ports. This is an old USB kext, which was dropped from use on Intel systems some years ago. So not sure it will work, but may be worth a try to see if one or more USB ports are enabled so you can complete the macOS installation.

I can't recall if you have created a UTBMap.kext in Windows, using the USBToolBox python script. If not you may want to see if doing so helps. This is an alternative and better option than using the GenericUSBXHCI.kext.

Hi, I have some recent updates.
With the help of https://github.com/hbyonly1/XHCILagFix , the usb issue is resolved.
I can boot into the installation and recovery dmg right now.
But still having amd gpu driver issue during installation.

And I have also checked my gpu device properties on recovery mode and got this.

Here is my current EFI file. Still have no idea which part is not working. Any help on the direction of resolving this issue is appreciated. Thanks
