[Guide] Laptop backlight control using AppleBacklightFixup.kext

i successfully patched everything...but there is one ultimate issue....as soon as i reboot or maybe shutdown & switch on my laptop the brightness level gets to maximum on boot...how to solve this??

Make sure you have latest Clover and have implemented NVRAM correctly.
If you installed EmuVariableUefi-64.efi, make sure you also installed RC scripts.
But the laptop in your profile will likely work with native NVRAM (eg. without EmuVariableUefi-64.efi).
Also, check your config.plist for any stray settings involving backlight.

i have the same error as "generation88" in 10.12.4... i am using native NVRAM and it's working good with 10.12 & 10.12.3.
any suggestion for config.plist

thats the normal boot glitch (you will see a patch in your config.plist to enable to help reduce the glitch)

Despite updating to Clover_v2.4k_r4049, applying the new patch for AppleBacklight in config.plist via copy & paste in PlistEdit Pro, making/installing a new SSDT-PNLF.aml file and adding the file to the Sorted Order list, and downloading/installing the new AppleBacklightInjector.kext via the command: sudo cp -R ~/Projects/probook.git/kexts/AppleBacklightInjector.kext /Library/Extensions and running: sudo touch /System/Library/Extensions && sudo kextcache -u / afterwards, although I have brightness control, kextstat indicates that the AppleBacklightInjector.kext in L/E still is not loading.

Is it possible that the "change GFX0 to IGPU" patch which was installed when applying the HP Envy guide is the likely culprit.
