Could you help me, please? I have on-board wifi/bt on my Rampage V Extreme. The chip is broadcom, wifi BCM4360 and BT BCM2070A0. I'm running Sequoia in the latest version, with all SSDTs applied, Kexts, USB mapping. The wifi enabled perfectly with OCLP, but I can't inject the correct firmware for my BT. MacOS is trying to load the firmware for BCM4350C2. My IDs are:
Product: 0x180a
Vendor: 0x0b05

I found several processes but none worked, and I couldn't understand dortania's tutorial.

Just sharing my experience with BCM94360NG, so anyone with the similar condition can try this.

TL;DR: Try to disconnect all power on your hackintosh, reset CMOS on your motherboard (I did it, not sure if it is necessary). This may save your BCM94360NG if it is in DFU mode.

I upgraded my system from Ventura to Sequoia recently. There were some problems with my OpenCore config so the upgrade failed several times and it seems made my Bluetooth module of BCM94360NG into the DFU mode.

The Bluetooth address was NULL, firmware version was "v0 c0" and the transport mode is "UART". It looks like in the DFU mode but not exactly same with other information in the guide. For example, the product ID in the USB section of System Information app was not reported as "0xf007" and there was not any "Broadcom Bluetooth Download Device". In the USB section, it just showed as two "Composite Device" under "BRCM20702 Hub", and there was not any "Bluetooth USB Host Controller". However, I can confirm it was also unfunctional in Windows and was shown as a unrecognized USB device (something like this, this is not the exact English name shown in Windows since my Windows runs in Chinese). Since, BCM94360NG runs in UART mode now, I also unable to flash the firmware to it.

Finally, I tried disconnecting the power cable of my hackintosh and reset CMOS of the motherboard. Then, BCM94360NG returned to functional after reconnecting the power. It seems Apple's genuine Bluetooth chip will exit DFU mode automatically if it is entirely powered off.
