Alienware 17r3: IGPU Failed to initialize graphics firmware, IOConsoleUsers: gIOScreenLockState 3

[Chinteni]

Hardware:

CPU: Intel Core i7 6700HQ

Graphics:
- Intel HD Graphics 530
- NVIDIA GeForce GTX 970M

Screens:
- Laptop: 3840*2160
- External: 1920*1080

Description:

Before I install the system, I copy-pasted the EFI from my friend's Alienware 17r3 who got a fully working Hackintosh installed.
The only difference from his hardware to my hardware is the display resolution.
He has a 1080p internal display, and I have a 2160p display.

When I install the system, the laptop IGPU screen works, but the external Nvidia one doesn't.
After it finishes the installation and moving on to the "Setup your mac" page, the laptop IGPU screen still works.
After "Setup your mac", everything is still normal.

Then I rebooted it, without any modification to the EFI or anything, IGPU stopped working.

What I assume is the error message:
"[IGPU] Failed to initialize graphics firmware. Falling back to host-side scheduling"

And then it is stuck on this:
"IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0"
I tried to restart it but same error.

Now I have no display working, and it is stuck on boot.
However, it did boot with a glitchy graphics driver when "0x12345678" is injected for the Intel platform-id.

After I successfully booted with the glitchy driver, the internal display is working but glitchy.
So I installed the Nvidia Web drivers and restarted it.
This time I did not change the platform-id before boot, so it is still "0x191b000" or something.
And when it started up, the external worked but internal still stuck in the same place.

So now, I tried to inject "0x12345678" again see if they would both work, but no luck.
I've searched a lot of times and tried a lot of things, but no luck.

Then I tried this from this post:

macOS High Sierra: IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0

Parts list: i7 4770 (HD 4600 Graphics I don't want to use) I'm not for sure on the motherboard, but I ran Yosemite on it prior to this. GTX 760 I had to install using the Intel graphics, as com.apple.WindowServer was crashing on installation. I thought that I could boot to macOS afterwards...

sudo touch /System/Library/Extensions
sudo kextcache -u /
rm -rf /Users/*/Library/Preferences/ByHost/com.apple.windowserver*

After I executed those commands and rebooted with single user mode, both of the displays worked.

I thought this is the end of the problem but the internal display stopped working again after another reboot.
And now I tried the script again but no luck.

What could be the problem?

EFI attached with some information censored.
