What was the problem with the kexts?

not sure, didn't look any further, probable in the future I'm gonna review my config and get it right to work with whathevergreen + lilu, now it's only on the gpu, so I'm not worried for the iGPU, maybe when i got the wifi card I'll look further

P.D. I'm in mac os Catalina 10.15.5, wondering if I can upgrade to 10.15.5

the only thing I did was to add the boot flag

agdpmod=pikera

the EFI folder is the same that I uploaded, and the Card is correctly detected

What I always do before updating my main OS, is clone it to an external USB3 drive with CCC, then do the update on it.

If that worked without causing issues, I know I can safely update the main OS.
