BrcmPatchRAM: No firmware available

Im trying to set up BrcmPatchRAM for Asus BT-400 dongle on 10.15.5

I'm using:

• OpenCore-0.5.8-DEBUG
• AppleSupport-2.1.7-DEBUG
• AppleALC-1.4.9-RELEASE
• IntelMausiEthernet
• Lilu-1.4.4-RELEASE
• VirtualSMC-1.1.3-RELEASE
• WhateverGreen-1.3.9-RELEASE

+BrcmBluetoothInjector.kext

+BrcmFirmwareRepo.kext

(Here I removed everything from Contents/Resources and added the BCM20702A1_001.002.014.1443.1467_v5563.zhx file from firmwares/0b05_17cb (the one for Asus BT-400) link: https://github.com/RehabMan/OS-X-BrcmPatchRAM/tree/master/firmwares/0b05_17cb

+BrcmPatchRAM3.kext

+ the 2 kexts from the same dir (tried with only BrcmFirmwareInjector2_0b05_17cb, then with both) BrcmFirmwareInjector_0b05_17cb.kext and BrcmFirmwareInjector2_0b05_17cb.kext

​

I get the error:

I understand the error but really can't figure out where the put the files.

​

From what I can see, the BrcmFirmwareInjector and BrcmFirmwareInjector2 have only this differences:

IOProviderClass: IOUSBDevice vs IOUSBHostDevice

IOCLASS: BrcmPatchRAM2 vs BrcmPatchRAM

I'm using PatchRAM3 kext, is this a problem? or only a coincidence?

​

LATER EDIT:

I removed everything from: BrcmFirmwareRepo.kext/COntents/Resources (previously I have put the zhx from the firmware).

Now I get:

But in system information I still have 4096version and bluetooth is very laggy
