Help: <a class='btn-link text-primary' href='/2020/12/install-macos-big-sur-on-supported-pc.html'>Big Sur</a> on AMD A6-9225 (Stoney Ridge) — Shuts Off at Boot

i have been trying to install macOS Big Sur 11.7.10 on my HP 15-db0xxx laptop:

Specs:

  • AMD A6-9225 (Stoney Ridge)
  • Radeon R4 Graphics
  • 4GB RAM
  • Realtek Ethernet (using RTL8111 kext)
  • UEFI boot, SSD (1,000Gb/1Tb SATA)

Current Setup:

  • OpenCore 0.9.8
  • Kexts: Lilu, WEG, SMCAMDProcessor, VirtualSMC, RealtekRTL8111
  • SSDTs: SSDT-CPUR, SSDT-EC-USBX
  • SMBIOS: MacBookPro15,2
  • Boot-args:diffCopyEdit-v keepsyms=1 debug=0x100 amfi_get_out_of_my_way=1 agdpmod=pikera

Issue i having: I get ACPI errors (length mismatch), then shutdown after a second. Ventura booted but got to https://support.apple.com/en-us/101666, but Big Sur won’t even show a boot logo...

My EFI: https://drive.google.com/file/d/1UmFeDbCCy5tNwmHgCDASJPIvC15jylkE/view?usp=sharing

[NOTE] 2 and 3 both display the same error. This is what happens before my laptop shuts off.

Any tips or EFI examples for Stoney Ridge + Big Sur? I’m stuck.
