They are reversed in pairs of 2 characters. So “0D 22 00 03” is what you need and if you reverse the nibbles it becomes “03 00 22 0D”. You have 30 00 22 D0 which is incorrect. I am using the same fix for my intel HD 4400 IGPU and it does indeed work correctly.
I'm still having trouble for some reason, and the last time I attempted to use Whatevergreen, I managed to glitch the entire system beyond repair (got stuck in a boot loop) and had to reinstall macOS from scratch. I'll recap all the steps I did, if anyone finds an error in what I did please let me know:
1. Following the instructions, I removed all the kexts and Clover injections that I had active; for me this meant removing FakePCIID_Intel_HD_Graphics.kext, IntelGraphicsFixup.kext and Shiki.kext from /System/Library/Extensions, setting config.plist/Graphics/Inject/Intel=NO, and config.plist/Devices/FakeID/IntelGFX= . I didn't have AddHDMI, FixDisplay, FixIntelGfx, AddIMEI, Disable UseIntelHDMI, or -disablegfxfirmware active, and I didn't have /Devices/Arbitrary, /Devices/Properties, nor /Devices/AddProperties in config.plist, nor anything in CLOVER/ACPI/patched.
2. I downloaded the compiled Whatevergreen.kext and Lilu.kext, and put these into the EFI/Clover/kexts/Other folder.
3. I used
gfxutil to get my IGPU path, for me the output was the same as in the guide,
DevicePath = PciRoot(0x0)/Pci(0x2,0x0)
4. I went into Clover Configurator, to Devices in the left panel, went to the "Properties" tab in "Arbitrary/Properties" on the right, for the Devices column I entered the above DevicePath "PciRoot(0x0)/Pci(0x2,0x0)", for the Properties Key column I entered "AAPL,ig-platform-id", for the Properties Value column I tried all three of the Haswell values in turn, with the hex values correctly reversed (so 0x0D220003 -> 0300220D, 0x0A160000 -> 0000160A, 0x0A260005 -> 0500260A).
5. Reboot, doesn't work, no matter which of the above three values I entered in the Properties Value column.
