Did you try the BrcmPatchRam kexts supplied by @gaghost in post #36 here? I was having a similar issue and those kexts fixed it for me. Remember they go in Clover/Kexts/Other, “Inject Kexts” set to “Yes” in config.plist. Uninstall all other BT kexts. BTinjector kext needed for Catalina only.
I tested the kexts in post #36 , and “Inject Kexts” set to “Yes” , restart catalina is fine , but finally shutdown laptop and cold boot still hang in Apple Logo...
Now I installed Win10 at the other ssd , first cold boot to win10 login window and then restart to Catalina , it can login MacOS with BT and WIFI fine. It also a warm boot method. no need to change the BIOS twice.
I guess cold boot may not intject the BT or WIFI kexts successfully so cause loading hang...
Change BIOS to restart BT Version is v7 c4689
Restart From Win10 BT Version is v7 c5799
