Okay so that worked and I followed all your steps correctly but the AppleBacklightInjector doesn't seem to load up. Here's the required terminal output and the files are in a zip.

The brightness control panel still doesn’t load up, I meant. Any fixes?

Your DSDT has an existing PNLF patch.
As per post #1, you must use only SSDT-PNLF.aml and remove any previous PNLF patch you may have added.
Read post #1 again. Carefully.
