ERROR [EB|#LOG:EXITBS:START] when updating from Catalina to Big Sur

[Ignoto10]

Hi, I have never been able to install Big Sur, with any efi, while instead wandering the internet.
I found someone else's efi based on ryzentosh, based on Catalina. But I was never able to get patches to work, so I made it work without them.

If I upgrade from Catalina to Big Sur, the log tells me OC: Kernel patcher result 17 for kernel algrey - cpuid set cpufamily - force CPUFAMILY INTEL PENRYN not found.

If I enclose my efi, someone can help me, I've been beating my head for a month to create a stable hackintosh, but I can't, I have performance problems on final cut.

Thanks to who helps me EFI : https://drive.google.com/drive/folders/1v68co93nVAJlGOFIrApGruPdCDAAMd-6?usp=sharing

Try this OpenCore EFI based on OC 0.7.9 adapted for a 12-core AMD CPU, running Big Sur or newer.

See if this gets you to boot macOS.

I pasted the EFI in the usb, I still have catalina, so I update Big Sur with your EFI on my USB, but as soon as I select update mac os installer, the pc turns off completely. How is it possible?

No idea why that happened, as I don't know how you have created your USB installer.
