Big Sur - OpenCore 0.6.1 - brcm94352 - Wifi dont work but bluetooth does

I've set up OpenCore 0.6.1 and Upgraded from Catalina to Big Sur beta on my Y50-70.
All works well despite Wifi , only wifi - Bluetooth works! Thats interesting cuz my brcm94352 has bt+wifi in one.
Tried changing brcmfx-driver to 2 , removing AirPortBrcm4360_Injector.kext from inside of AirportBrcmFixup , set MaxKernel 19.9.9 in config.plist. Nothing.
Also tried removing other kexts for broadcom, deleting all brcm kexts despite BrcmPatchRAM, removing all brcm kexts.
Anything has same result of not working wifi, even it didnt show as wlan interface when I wanted to add new entry in network settings , just could add bluetooth and lan - unfortunate got lan input not working so I've got no internet on my hack rn.
Does anyone know how can I figure brcm94352 to work on big sur?
