How to Fix Opencore update won't boot Big sur or Ventura but older version works? Help

This mini-guide provides a structural approach to troubleshoot and fix the issue.

Prerequisites

  • Confirm your hardware specifications (CPU, GPU, Motherboard).
  • Ensure you have a bootable recovery USB and backup your EFI.

Fix Steps

  1. Boot with -v keepsyms=1 debug=0x100 to identify the exact kernel panic.
  2. Validate your config.plist using ocvalidate.
  3. Ensure your EFI matches the Dortania guide specifications for your CPU generation.

Verification

  • Reboot and verify if the functionality is restored and stable under typical usage.

Original Question:

EFI package I'm using for this laptop is premade from someone else, same specs to a T Big sur works perfectly.

I figured I'd use Opencore updater to update the EFI for Ventura but it won't even boot into bigsur anymore post update.

Tried to leave update EFI on while reinstalling bigsur with the USBs EFI then installing Ventura through the app store hoping it would boot. But once the its reboots it's stuck going back to open core everytime this leading me to the Mac recovery program. What should I poke around for in my EFI to make it work with the latest version of open core?

I got the EFI from here, worked flawlessly out of the box for bigsur. https://github.com/danang-id/ASUS-TP412FA-ESP
