MSI Board Cant Upgrade to Monterey

[liveig105]

So i successufully install Big Sur 11.6.2 with opencore 0.7.6, but when i update to Monterey I always got stuck at forbidden sign (previous error is Lilu dev: @ found dead pci device GFX0)

My system:
CPU : 5600x
Mobo : MSI B550 a-pro latest bios
VGA : radeon 5600xt

Already make USB Map for my motherboard

And I attach my EFI, thak you

It's not going to work I'm afraid. Some MSI boards can use an older BIOS to get Monterey working but as you've got a 5000 series CPU that's not an option.

Yes its very disappointing that all of us who purchased MSI got the s@!t end of the stick. I was able to downgrade my bios but will never have the option for a newer gen cpu, buying a different mobo is not acceptable. I hope there will be a fix, I wonder if anyone knows why MSI boards are the culprit?

I've heard that Russian hackers have modified the original BIOS to install Monterey properly

I recommend you to switch to Asus or Gigabyte motherboard. I had X570A-PRO and just bought X570 Aorus master. Much faster boot time and much more helpful info / ready EFI folders to download from internet.

MSI stinks.

Downgrading Bios to v12 Version wrked for me after spending 2 days trying to boot into monterey. Now everything works well so far.
