Hey dude,
Firstly I would like to thank you for sharing your hard work with us, it would not be possible for me to do without your help.
Everything seems to be working good apart from bluetooth, It's turned on but not finding and pairing to device.
From other issue posted I tried copying BrcmPatchRAM2 and BrcmFirmwareRepo.kext to S/l/e and rebuilding cache but still had no luck
