You did not follow the guide.
Problems:
- SSDT-PNLF.aml is not loading due to it being omitted from config.plist/ACPI/SortedOrder
- AppleBacklightInjector.kext may not be installed

AppleBacklightInjector.kext should be in L/E and not S/L/E right? It is installed to L/E...Ill work on the config.plist
 
Ok, so I added SSDT-PNLF.aml to the end of ACPI/SortedOrder and I see AppleBacklightInjector.kext now loading...but still no brightness slider in Displays

As per post #1, you must rebuild cache and reboot.
If still not working, read post #1 regarding patching EDID.
