Thank you!

I configured my post efi like you mentioned in your link leaving only these kexts

AirportBrcmFixup.kext, AppleALC.kext, AtherosE2200Ethernet.kext, CpuTscSync.kext, ECEnabler.kext, FakePCIID_Intel_I225-V.kext, IntelMausi.kext, Lilu.kext, LucyRTL8125Ethernet.kext, RealtekRTL8100.kext, RealtekRTL8111.kext, RestrictEvents.kext, RTCMemoryFixup.kext, SmallTreeIntel82576.kext, USBInjectAll.kext, VirtualSMC.kext, VoodooPS2Controller.kext, WhateverGreen.kext

everything booting fine... no hd acceleration, no touchscreen, no hdmi,.

Changed sone values for the gpu generated by hackintool (tried with
device ID: 0000A53E
device ID: 0900A53E
device ID: 0005A63E
with SMBIOS MacbookPro16,3, 15,4 and 14,1 both ending up with:

IOconsoleUsers:GIOScreenLockState 3

I really have no more plan where to go on.
I've probably read almost all forums due to this topic and spent the hole week with it.
Somewhere there is a gpu problem, caus without device property PciRoot(0x0)/Pci(0x2,0x0) gpu running well.
Can you help me plz!

Dear members. Is there anybody out there, who got a Latitude 7400 2 in 1 to work properly with full GPU acceleration on Big Sur?
As far I tried all kinds of settings, EFIs as well as I tried to generate my own from sample on.
No luck.
I got the Installer running with an Olarila image and could install Big sur 11.4.
Somehow I found a EFI, which allows my trackpad, touchscreen, Audio eaven the Intel WIFI card to work quite properly - as far tested.
I tried different SMBIOS with different framebuffers, device-ids on and on.

 

I updated and modified my BIOS (1.11.0)
Where I unlocked my CSR with:

setup_var 0x6ED 0x00

 

and set PreAllocated and total allocated settings with:
Setup_var 0xA10 0x2
Setup_var 0xA11 0x2

Actually I can work on my Laptop but I have no acceleration - only 7MB and my HDMI is not working - not buildt-in hdmi and not a usb-c -> hdmi dongle (but LAN over this dongle works though). That sucks, cause I need my monitor for work - my eyes are not the best!!

My spec are: DELL Latitude 7400 2 in 1 (5WRVH) with 16GB RAM, i7-8665U Whiskeylake with UHD 620 GPU and Full HD display

My only modification is a Samsung MZ-V7E1T0BW 970 EVO 1 TB NVMe M.2 instead of the original NVMe shipped with the laptop.

 

I've spent allredy over 4 weeks trying and trying....
I attach my EFI folder and ask anybody who can give me a hint or send me his EFI plz!!!!
Also can give a reward somehow for your spent time!
