Hi Edhawk, I'm not really sure about at which point, I made a video and take a screenshot of the last lines before it goes black. I'm also attaching the video itself (on a zip, it doesn't allow me to attach it in mp4 format).

 

[Edhawk]

Lots of errors visible in the video - USB, PS2, SMBUS but none of thees were the cause of the final KP. Couldn't see the final KP cause, as the text was blurred and moving too fast.

Post a copy of your current EFI.

Post a copy of your system DSDT.aml table.

Ok, there's a copy of the EFI, insidde the folder there's also th DSDT. Thanks!

 

[Edhawk]

Try this EFI, it has been revised based on the devices present in your DSDT.aml, using both manual checks and Corpnewt's SSDTTime python script. A copy of the SSDTTime Results folder is attached.

It contains a copy of the latest AMD Kernel Patches, plus the additional TSC patches you had in the previous config.plist.

I have removed a number of SSDT's, Drivers and Kexts. To correct duplication of the HFS+ driver, and to remove some unnecessary kext and SSDT's.

Add your Serial Number, MLB, ROM and SystemUUID to the config.plist.

DO NOT CHANGE ANYTHING ELSE!

Post your results so we can see what happens with the revised EFI.

Hi, now I cannot get the opencore menu. It says only:
BEP: Invalid revision 3 (!=5) in loaded driver
Halting on critical error

In NVRAM--Add--4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 it says AMD Ryzen 7 5800H, but I have a Ryzen 7 4800H. I don't know if it matters

This should have that error fixed. No other changes made.

Try this one, it helped me install Sonoma, it works pretty well, I think everything...

Hi no one of your kindly shared efis worked in my 15AR5H laptop. I always get what it seem some kind of problem with the usb (USB lotsofnumbersandletters) will be reset. Then some times it goes to a black screen and sometimes don't. I've tested it with two pendrives but nothing. Then I thought maybe I had to map USB better or something and make the map. When adding UTUSB.kext the result is the same.
Then I thought ok, let's make another installer from scratch and I don't know why but osx made me a pendrive without efi partition ( I should make it by myself? I think the other times it was automatic)
So I'm kind of stuck. I'll redo another installer and then test the efis you posted. I'll let tou know if there's some luck.
Thanks to all for your time and help

EDIT: I made a new usb installer and creation seems ok, there's the EFI partition


EDIT 2: I upload some photos of the lasts attempts. Is always seems to finish the same way with the usb error.
