Keep in mind IntelBacklight.kext is a bit broken on 10.12.4.
Suggest you go back to 10.12.3 unless you want to work that new problem out (requires custom AppleBacklightInjector.kext... google it... I have an old guide for doing it, but it is for Ivy Bridge, not Skylake...)

Just a question how can I downgrade? Should I reinstall?

Your ACPI files are not patched correctly (for example, no evidence of "OS Check Fix" patch).

Ohh so everything in the ACPI guide should be install!! Let me try if I fix it.

After Adding:
"Fix _WAK Arg0 v2"
"HPET Fix"
"SMBUS Fix"
"IRQ Fix"
"RTC Fix"
"OS Check Fix"
"Fix Mutex with non-zero SyncLevel"
"Fix PNOT/PPNT"
Rename:
GFX0>IGPU
HECI>IMEI
HDAS>HDEF
and disable nvidia to my DSDT, my screen start to glitch. The only thing I did is the patch my DSDT, so I will upload my DSDT.aml

It is not valid to rename in DSDT and not in the SSDTs.
See guide: https://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

Am I Patching my ACPI correctly now? I rename GFX0 to IGPU on SSDT-1 and SSDT-11.aml because only both of them got GFX0. I also got a problem now, last time I boot I didn't use my external HDMI display, and now even my external shows black screen when I boot up, it only shows a mouse.
I forgot to say, I reinstall it from 10.12.4 to 10.12.1 and upgrade to 10.12.3

Edit: Never mind, I fix external display not showing by changing the resolution, but still built-in-display still won't show anything.

Problems:
- SSDT.aml is not loading due to it not being listed in SortedOrder (therefore no CPU PM)
- QE/CI not implemented (eg. graphics not working) due to incorrect use of FakeID/IntelGFX

I thought I add ssdt.aml in SortOrder on the first order. Also what can I do to fix incorrect IntelGFX? Replace it?

Look at your SortedOrder list in config.plist.
FakeID/IntelGFX not required for your hardware. Do not inject a FakeID.

Am I adding it incorrectly? Because I see ssdt.aml in config.plist

I looked at the Clover bootlog to determine why CPU PM was not working (looked for SSDT.aml, and didn't find it).

Your Clover bootlog, extracted from the ioreg in post #54 indicates no files in ACPI/patched.
Probably because you're booting from USB, and not the EFI/Clover that you attached.

Ohh Ok I will upload a new file. Also I think didn't install anything that is called FakeID/IntelGFX, I also check S/L/E, there isn't anything call
