After rebuilding cache, reboot.
Please use gen_debug.sh as per FAQ for collecting problem reporting files.

after running gen_debug, backlight works! not sure what happened, maybe the way it calls rebuilding cache.

Rebuild cache/reboot always required to allow KextsToPatch entries to kick in.

Thanks, I assume "kextcache -i /" is the correct way for 10.13/10.14 ?

Requires sudo:

sudo kextcache -i /

Or the old method also works:

sudo touch /System/Library/Extensions && sudo kextcache -u /
