I will reinstall 10.12.6 again.
From what I found I installed 10.12.5 and upgrade to 10.12.6. Even I changed ig-platform-id 0x59120000, fakeID IntelGFX = 0x59128086. It gave the same result. I only booted it by using 0x19320001 or 0x19120000 with FakeCPUID = 0x0506E3 (as you saw in my config.)
Last night I did again. I used ig-platform-id 0x59120000, fakeID IntelGFX = 0x59128086 but it booted kernel panic.
When I checked in System report> graphics /display. it said "kext not loaded".
