I followed the guide, but after reboot I don't have brightness control and slider... Removed PNLF patch from DSDT, installed the config.plist patch and the kext... Could someone verify my files to see if I am doing something wrong?

Brightness to black at the lowest setting is the expected behavior, as per Apple design.
Brightness keys are covered in the normal backlight guide linked by the FAQ.

You have a conflicting PNLF definition in SSDT-6.aml.

Read post #1, "Problem Reporting".
Make sure you provide *all* files and output requested.

You must be in the ~/Projects/probook.git folder when you use 'git checkout beta'.
You must also install iasl as per ACPI patching guide: https://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

I had MaciASL installed in my applications folder (updated binary form your link). Manually installed "makefile" in user/bin as shown. Though again when attempting to build the SSDT-PNLF.aml file, I am getting the same error in terminal: "make: iasl: No such file or directory make: *** [build/SSDT-Config.aml] Error 1.

'makefile' should not be installed anywhere. And there is no user/bin directory.
You must install iasl to /usr/bin.

Note that if you have MaciASL.app in /Applications, you can copy the iasl from it to /usr/bin:
Code:
sudo cp /Applications/MaciASL.app/Contents/MacOS/iasl61 /usr/bin/iasl

And since putting makefile into /usr/bin is nonsense, you should remove 'makefile' from /usr/bin:
Code:
sudo rm /usr/bin/makefile

I am not trying to be difficult or waste anyone's time in my attempt to complete this procedure. I am completely aware that the user/bin folders are hidden folders on the root and not a directory. I do not understand why I was perfectly able to generate/make/build a SSDT-HACK.aml file with iasl in the HP Envy Haswell series J/K/Q/N guide yet I am am unable to generate/make/build a SSDT-PNLF.aml file with this guide as the necessary component/file is apparently not on my system.

Can someone please explain the iasl user/bin installation procedure ?

No such thing as user/bin. It is /usr/bin.
It is directory. A folder is the same as a directory. (note: /usr/bin is not hidden on my system).
If you followed the HP Envy guide, you should already have iasl in /usr/bin, as it is downloaded by download.sh and placed there by install_downloads.sh.

I already explained how you can copy iasl61 from MaciASL.app to /usr/bin. Read post #18.

You can check that you have iasl installed correctly by:
Code:
ls -l /usr/bin/iasl

Should show:
Code:
-rwxr-xr-x@ 1 root  wheel  1067924 Dec  8 17:56 /usr/bin/iasl

And:
Code:
which iasl

Should show:
Code:
/usr/bin/iasl

And:
Code:
iasl -v

Should show:
Code:
