Keyboard and trackpad not working after installing Sierra 10.12.6

Hello! After long, hard work, I've managed to install Sierra on my HP Omen 15-ax201nj Laptop.

For some reason, the keyboard and trackpad are not working right now. I've tried to install the VoodooPS2Controller.kext but I keep getting a message that I could not be installed. I've tried to repair permissions and rebuild cache and boot with the "-f" flag too, no success though.

If anyone knows how to help, please keep in mind that I'm new at this and specific instructions would be highly appreciated!
