BrcmPatchRAM2 for 10.15 Catalina (Broadcom bluetooth firmware upload)

Mieze · October 15, 2019

As BT depends on working USB ports, check your USB configuration.

Just wanted to chime in and give thanks to Mieze for the best BT solution for Dell 1830 I've seen so far. This card overall is a nightmare, further solidifying my disdain for Broadcom chips. While wifi works great OOB on Mac OS, BT has been a pain in the butt, while in Windows the wifi driver is outdated and overall horrible (connection drop outs, disconnects etc. and latest version from 2017 causes a random BSOD). I really wish we had more options for compatible cards apart from Apple Airport ones (which due to the necessary adapter in most cases don't fit in laptops).

Also, for the member above with issues with webcam and BT, its your USB port mapping that's the problem. Use the script here to create a custom SSDT with all your USB ports mapped:

Hi @Mieze

is this still correct for your v2.3.0d2?

BrcmPatchRAM: for 10.10 or earlier
BrcmPatchRAM2: for 10.11 - 10.14
BrcmPatchRAM3: for 10.15

Mieze · October 16, 2019

@ellaosx Yes, but BrcmPatchRAM3 has also been successfully tested under Mojave!

@Mieze Hi, I'm having trouble with BT, sometimes it works and sometimes it doesn't (I get this the most)... I activate BT in my DW1830 with the following steps... I hope this helps:

macOS Catalina 10.15 latest supplemental update applied (15th Oct).

DW1830 (BT: [0a5c:6410] BCM2045A0).

HP EliteBook 840 G4, in BIOS the Wireless button is unlocked as a reference, since I've pin-taped my DW1830 it only affects BT.

My USB ports are working as intended, already validated and limited using SSDT method, thanks to: https://www.reddit.com/r/hackintosh/comments/9wkuc6/script_to_create_ssdtuiacamlinjector_kext/

kexts installed:

Version 2.3.0d3

➜ Extensions pwd
/Library/Extensions
➜ Extensions ls | grep Brcm
AirportBrcmFixup.kext
BrcmBluetoothInjector.kext
BrcmFirmwareRepo.kext
BrcmPatchRAM3.kext

Here's what I did:

Power on my laptop and BT was not available.
Checked logs and noted this:
1. (BrcmPatchRAM3) BrcmPatchRAM: uploadFirmware could not open the device!
Manually loaded kext:
1. sudo kextutil -v 5 /Library/Extensions/BrcmPatchRAM3.kext

Pressed the BT on/off switch in my laptop.
Manually loaded BrcmPatchRAM3.kext.
Still no BT.
Pressed the BT on/off switch again.
Loaded BrcmPatchRAM3.kext again, then checked logs.

BT becomes available and can pair with my devices.

There's something weird about the on/off switch but idk if the physical button has something to do in my scenario, I see addPowerChild and removePowerChild methods in the logs, I'm guessing those are trying to do the same as if I pressed the button.

This is a power management issue because firmware updates fail, when the device is power cycled by the BIOS. Use the debug builds of the kexts in order to collect more data.

By the way, it's quite normal that firmware updates fail after wakeup on some notebooks, including my own, but the upgrade will be retried until it succeeds. It's not unusual that it takes 3 or 4 attempts until BT is back again.

Thanks for your answer @Mieze

Boot macOS Catalina (Cold or warm it doesn't really matter).
Pressed the Wireless button 4 times (every 5 secs), in the last (4th) I get BT working.

I disabled the wireless button in BIOS setup because I realized that macOS doesn't cope well with it because there is no such button on real Macs.

EDIT: Pin-taping devices may cause trouble as the BIOS will assume that the device isn't present and may fail to power it properly on boot/wakeup but I know the problems with WIFI whitelisting on HP and Lenovo notebooks.

I have just tested all version in this topic. All of them does not work for me if i put following ket in to L/E:

BrcmBluetoothInjector.kext
BrcmFirmwareRepo.kext
BrcmPatchRAM3.kext

However it work if it use following way:

Put BrcmBluetoothInjector.kext, BrcmFirmwareRepo.kext into L/E and BrcmPatchRAM3.kext into clover

Or put BrcmBluetoothInjector.kext, BrcmFirmwareData.kext, BrcmPatchRAM3.kext into clover

Thanks to vit9696 and Mieze!

Hi @headkaze I see they merged the changes but the last release over at git is from July 16 2018 will they be making a release version soon?

Thanks, this works for me too.

The Logitech Triathlon M720 is very difficult to get paired, but this just worked without problems.

Yeah sorry I didn't realize there was no binary up yet. Please use Mieze's links for now.

Mieze · October 18, 2019

Here are binaries of the latest build which I'm using for test purposes. Please use this as an intermediate solution as long as there is no official release.

Thank you Mieze and Headkaze.

PepsiColaNYC · October 19, 2019

This is really great, thanks so much for making this work so well.

On Catalina, I had a DW1560 with working WiFi but wasn't able to get the Bluetooth working correctly. However, I suspect a USB configuration issue, rather than an issue with these kexts. I returned the DW1560.

Now I have a Broadcom 20702A3-based USB BT dongle. I installed the kexts as instructed in /L/E, and confirm updated firmware v14 c5860 after a cold boot. However, things are not yet working 100%:

Bluetooth shows a disabled icon and "unavailable" after boot, even with v14 c5860 firmware correctly installed. If I unplug and replug the dongle, Bluetooth then becomes available. Could this be a USB configuration issue?
Even when Bluetooth is working, Airdrop / handoff / continuity don't. System Report shows Handoff Supported as "No". I tried the "10.11.dp1+ BT4LE-Handoff-Hotspot, credit RehabMan based on Dokterdok original" patch but it does not seem to have made a difference.

@PepsiColaNYC Why are you asking us? Ask your kernel logs! You'll find the answer there!

Help, please? I have an Azurewave (4352HMB) [13d3:3404] that worked prior to the upgrade to Catalina. I followed the instructions and am using BrcmPatchRAM3, BrcmBluetoothInjector, and BcrmFirmwareData, all injected via Clover the the kext/other folder. Bluetooth shows up but does not detect any devices. System info shows the firmware is not loaded (4096 v14). Not sure what is going on... here is the log:

Could somebody upload the binaries? Every download link I've found on this thread gives me 404...

Thanks!

Mieze · October 19, 2019

@AlbertoSONIC You are one click away from it, just have to download! :hysterical:

@Mieze Thanks for your great work. Is it possible for you to add AR3012 [0489:e036] support? I am running the High Sierra.

这是我用作测试目的的最新版本的二进制文件。如果没有正式版本，则替换为中间解决方案。

You might want to look at your kernel logs!
