Dell Latitude 3480 Catalina update issue

[Skynet92]

I'm running vanilla Mac Mojave 10.14.6 in my laptop. Though it is running well, but facing some minor issue like, HDMI port is not working. Can anyone please help me to figure out the issue. and also when I'm trying to update to Catalina, after the first reboot the system stuck at "AppleIntelLpssI2CController". Please help me.

You need this patch :

FIX for boot hangs after BIOS update (ACPI PATCH)

This is an ACPI Patch for the people who update to the last bios and can't boot. My board is the MSI B360A-Pro and has the latest bios 7B22v27. First add the patch (the blue line from the picture) to clover config, then apply the Bios update. To easily add the patch using terminal, read post #48

It did work because you have progressed further, now you have a new issue :

For this you need to put SSDT-EC.aml in /EFI/CLOVER/ACPI/patched.
