I installed High Sierra by following RehabMan's guide (https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/) and fixing things one by one.

The problem I now face is that after turning off the screen (by closing the lid or going into sleep mode) and then turning it back on, the display flickers. This is similar to the video present in this post: https://www.tonymacx86.com/threads/help-black-blinks-flicker-after-wake-up.210476/

I used AppleBacklightInjector.kext to get the backlight working and patched the DSDT to disable discrete graphics.

I've attached the Problem Reporting files as required.

Any help is appreciated.

Remove ACPI/patched/SSDT-XCPM.aml... it is not needed and conflicts with config.plist/ACPI/SSDT/Generate/PluginType=true.

Note that you also have various kexts installed incorrectly:
Code: 
Kext rejected due to improper filesystem permissions: <OSKext 0x7fa7ec060460 [0x7fff91085af0]> { URL = "AppleHDAController.kext/ -- file:///Library/Extensions/AppleHDA.kext/Contents/PlugIns/", ID = "com.apple.driver.AppleHDAController" }
Kext rejected due to improper filesystem permissions: <OSKext 0x7fa7ec043280 [0x7fff91085af0]> { URL = "IOHDAFamily.kext/ -- file:///Library/Extensions/AppleHDA.kext/Contents/PlugIns/", ID = "com.apple.iokit.IOHDAFamily" }
Rejecting invalid/inauthentic kext for bundle id com.apple.iokit.IOHDAFamily at location IOHDAFamily.kext/ -- file:///Library/Extensions/AppleHDA.kext/Contents/PlugIns/.

Refer to the FAQ for correct kext installation procedures.

Thank you for replying. I removed SSDT-XCPM.aml and installed the kexts correctly. The problem still persists. Attached the updated Problem Reporting files.

Any change requires new problem reporting files.
No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

I've attached the files. The only change I made was using MacBookPro13,1 in SMBIOS. Backlight was working at the time of creating this thread. (I had followed your guide to get it to work: https://www.tonymacx86.com/threads/...rol-using-applebacklightinjector-kext.218222/)

Backlight control now working (probably due to rebuilding cache as per guide).
EFI/Clover missing.
You might read here regarding EDID override:

I extracted my EDID and injected the updated value using Clover. I still see the screen flickering after wake. I've attached the problem reporting files including the Darwin dump files in the same zip.

Note: I tried using all the different displays in FixEDID application but none of them seem to solve the problem.

You might try other ig-platform-id values...
Also, make sure legacy boot/csm is enabled.
