Regarding this guide  , I've successfully installed Monterey 12.4 on my laptop, but when I updated my EFI to OC 0.8.3 to install Venture beta 3, I've come with this issue that my GPU only read 7MB.. I used MBP 14,2 SMBIOS to be able to update. any help with how to repatch my GPU? Thanks ahead ❤️

You must have missed the minimum requirements...

Broadwell iGPU is not supported and patches may never be provided. Ventura only officially supports Kaby Lake iGPUs and later and provides no driver whatsoever for older generations. You can go back to Monterey and stick to it.

You don't understand, no support for Intel iGPU before Kaby Lake generation.

 

The trick of using Kaby Lake framebufffer and faking KBL iGPU id only works for Skylake because KBL is a small evolution or optimization of SKL (Skylake microarchitecure is shared by subsequent Intel generations up to Comet Lake). This trick does not work for older iGPUs such as Haswell or Broadwell though and it's not bug free on Skylake.
