Hi MaLd0n, I tried making folders with this technique, but miserably failed with no touchpad and wifi working. So I switched over to my original EFI which I had discovered from internet and then edited it for my laptop. In this everything is working except the HDMI which you told can't be fixed and I have an issue that after I put Mac OS Big Sur on sleep and wake it up, there is just a black screen and everything else(audio, etc.) is working fine.
Can you please help me fix this issue
Thanks you for your time
