I checked the log, you didn't disabled the Nvidia GPU. there is EHC1 and EHC2 (possibly GPRW USB "instant wake" patch will fix it)

yes, that what I meant.

Try attached zip.
- Disabled Dedicated GPU with "disable-external-gpu" device-property
- added GPRW patch (binary + SSDT-GPRW)
- Sleep/Wake patch (SSDT-PTSWAK)
I just noticed that with the efi you gave me here I get this error before opencore loads the boot menu (the os still boots fine though)

By the way, I get this error when I try to update opencore and unlike the previous error, the os won't boot at all (I just see apple logo without progress bar)

you need to update config.plist accordingly, read OpenCore documentation and changelog, compare you current config.plist with included Sample.plist

*Edit: DummyPowerManagement Property was moved form Kernel -> Quirks to Kernel -> Emulate

I'm trying to understand how to compare but am a little confused. Should I update sample.plist with the things it said were missing from it or should I update my config.plist with the things it said were missing from it?

@chilledHamza Well, I tried to match the sample.plist with my old config.plist and then used it but I kept getting errors for some kexts which I didn't have so I removed them from kernel -> add in config.plist and then when I tried to see if it solved the issue I got another error which I'm not sure what it means

@chilledHamza Sorry for tagging you again and again by the way xD

Well, I fixed the opencore issue. The dim boot screen issue was caused by ssdt-pnlf and I solved it by replacing it with ssdt-pnlf-cfl. Well, I'm not sure if I can say fixed because even though ssdt-pnlf-cfl fixed my dim boot screen issue, it also broke the brightness controls. I mean, I can still control brightness but only the first 7 levels make a change and if I continue to press the brightness up levels it's already full brightness but the bar adds more levels. Hope you understood what I meant. Any idea how to fix this?

@chilledHamza Hello, I am back again with a problem. Unfortunately I wasn't able to fix battery status. Can you please check my problem reporting files.
I learnt and applied all the patches as told by you and rehabman's guide, still no success though.

Basically, you were using config.plist that was configured for some other version of OpenCore. Each new version changes a few configs or changes/renames the key/attribute. So, you have to update old config.plist according to new OpenCore documentation. OpenCore Sanity Checker can be a little handy for parsing config.plist, but don't rely on it too much.

If you have a i7-5500U CPU (and HD 5500 IGPU) then the right patch is SSDT-PNLF.
SSDT-PNLFCFL is for 8th-Gen Coffee Lake CPUs, currently using it on Lenovo Legion with i7-8750H (UHD 630 IGPU).
Try AppleBacklightSmoother along with included SSDT-PNLF
