Poor bluetooth connection

Hi guys!

Unbelievably, I almost got everything to work.

HDMI- Works
Wifi 5ghz and 2.4 ghz - Works
Audio Sleep/wake problem- Works
BT - Works (almost)

I got BT to work, but the connection sometimes disappears and breaks. I have done as follows below. Does anyone have the similar problem?

Installed FakePCIID.kext to /s / l / e
Installed FakePCIID_Broadcom_WiFi.kext to / s / l / e
Installed BrcmPatchRAM2.kext to / s / l / e
Installed BrcmFirmwareRepo.kext to / s / l / e
And put in 'fcvo'...
