Black screen on Internal Display, UHD 620, Big Sur

I get a kernel panic with the EFI you've posted @tyraenor ...

Seems like something is changing


Thanks

Hi again, please try this one.

 

[xMooN]

Trying it right now!

Boots into a blackscreen with remote control working. Pfff...

I do not get it. I have a notebook with the exact same cpu and iGpu here and it works fine. It has to do something with the bus I guess. It is worth a try...

I really don't understand how to patch the buses. Not really familiar with Dortania's patching guide
