Laptop LCD extremely dim when booting

Intel i5 8th Gen (Coffee Lake)

Intel UHD 620 Graphics

16gb ram

I used Dortania to set up the EFI.

Everything works during booting, but on the installation screen (where you see disk utility) my laptop LCD just becomes extremely dim.

I have added the following to my boot args (-v keepsyms=1 debug=0x100 alcid=1 -igfxblr igfxonln=1 enable-backlight-registers-fix) and I have also put the ACPI SSDT-PNLF.aml.

Is there any kexts I should install at this current moment?

I also don't think trackpad and keyboard works as nothing seems to be happening when I use both (using a USB mouse and keyboard, I can see changes)

Any help would be appreciated thanks!
