Opa @MaLd0n. Usei a EFI premade do post e consegui bootar na instalação do Big sur no meu notebook. O teclado não está funcionando mas consegui formatar o disco e colocar pra instalar o sistema. O problema é que na segunda parte da instalação o sistema trava em "menos de 1 minuto restante" e fica assim pra sempre. Quando reinicio manualmente, não aparece nenhum disco de inicialização, apenas pra começar a instalação novamente, e fica nesse ciclo. O que pode ser?

Had time to look at it again, I re generated EC on Windows machine (same machine) but I still getting AppleNVME Assert failed: 0

How to clear cache / boot cache ?

I have same problem, but my device ec name is "EC" no "EC0" anymore. Do I need injected EC again?

Same, sir!

I managed to start the installer, complete the installation; but now when starting the "macOS installer" to complete the first boot it appears to boot; the graphic screen starts ; I can see the progress bar for about 5s and then it starts to shutdown and reboot.

 

I can't see any obvious error; the text showing is what I would expect to see if I cleanly shutdown the mac:

 

Has anyone seen something similar before?

 

I'm not too sure where to look next.

Have you put the boot args keepsyms=1 and debug=0x100 ?
