i was not able to boot at all from main clover screen when i placed SSDT-KEY-DELL-WN09.aml in my ACPI/patched folder!

after i hit enter from my clover i got black screen with no text at all

 

[RehabMan]

okay re-done all the things as per guide
my brightness increased but there is no brightness slider

attached the new problem reporting files!

Looking at your ioreg, it is quite obvious that you have SMBIOS truncation.
As with many Dell laptops, you must set config.plist/KernelAndKextPatches/DellSMBIOSPatch=true.

And as @feartech mentioned, your kexts are still not installed correctly (no possible way you can consider FakeSMC.kext not a "kext you need").

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.
