I tried the below options and am still stuck at same place, please check the attached screenshots for the same.
Any help really appreciated. attaching my error screenshot and EFI, can someone please have aloo and correct me.

Error:
“ OC: Kernel patcher result 27 for kernel (XLNC - cores and threads calculations #2 - 12.0) - Not Found
OC: Prelinked injection AirportItlwm.kext () - Invalid parameter “

1. Followed https://dortania.github.io/OpenCore-Install-Guide/
2. OpenCore Legacy Patcher https://dortania.github.io/OpenCore-Legacy-Patcher/
3. https://github.com/luchina-gabriel/BASE-EFI-AMD-RYZEN-THREADRIPPER
4. Tried with OpenCore configurator (https://mackie100projects.altervista.org/opencore-configurator/)
5. Tried with SMBIO MacPro7,1 and MacPro5,1 all stuck at above error only.
6. Changed the three algrey - Force cpuid_cores_per_package patches and alter the Replace value (I used "10" as I have AMD RYZEN 9 3950x 16Cores)

NOTE: Used latest patch https://github.com/AMD-OSX/AMD_Vanilla/tree/master
NOTE: My earlier build OC 0.7.2 with BigSur (11.6) working fine. Want to install fresh macOS Monterey.

Below are my Hardware details:

You've not got the latest patches. There should only be 16 and the error mentioned isn't included anymore. As for AirportItlwm.kext it's entered incorrectly in your config or the kext is missing from the EFI.

Thanks a lot for your reply and spend some time to see my issue.

As I'm desperately trying to install macOS Monterey with OC 0.7.5, trying with multiple EFI found on this forum.

Sorry for uploading the wrong EFI, please find the correct EFI attached.
I downloaded the latest patch from https://github.com/AMD-OSX/AMD_Vanilla/tree/master

This can be your starting point.
Be very patient at all the reboot. to be sure wait until 15 mn
Put the wifi kext for Monterey, be aware to reset your Nvram
chooe the good starting disk each time in the Bios

I tried this too with little modification like below.
1. SMBIOS details.
2. SETTING THE CORRECT CORE COUNT FOR MY CPU " 10 "
3. BIOS setting as per guide.

Still stuck at the same point :-(

@Danish297 I just ensured it was the latest OpenCore and gave it a cleanup. It's a good idea to clear the NVRAM when you make changes to the EFI.

Update OC, kexts and kernel patches then clear NVRAM. Update should then work.
