BrcmPatchRAM2 for 10.15 Catalina (Broadcom bluetooth firmware upload)

barrrrt · October 9, 2019

Thx for the hint: Tomorrow Morning ill try to recreate the kernel cache! Rest is checked.... (but ill double check again)

Final Update:

The cause of my Problem was, that in the Hackintosh are 2 HDDs inside. I dont know why, but the boot Order was changed. And on the other HDD was another Clover Installation available. After switching the boot Order into the right Order, the System did boot up and your bcrm Files were loaded correctly. BT it working again ... argh..

@SchillerX Firmware upgrades usually survive a warm boot so that there is no need to upgrade again. In order to get more logs, use the debug version of the kext and perform a cold boot.

@speedyrazor Remove headkaze's kexts completely and try mine (BrcmPatchRAM3.kext, version 2.3.0d1) from this thread. Install BrcmPatchRAM3.kext, BrcmFirmwareRepo.kext and BrcmBluetoothInjector.kext to /L/E. Make sure that you don't mix headkaze's kexts with mine as this won't work.

Weird... but I did a cold boot in safe mode and BT was working (immediately paired with my Magic Trackpad 2)... the logs obviously indicated that BrcmPatchRAM3.kext and BrcmFirmwareRepo.kext were not loaded in safe mode.

Cold booted in normal mode and now with only BrcmBluetoothInjector.kext loaded in /L/E my BT is working again (DW1830).

I'm not sure how to check BrcmBluetoothInjector.kext logs or how it's affecting my system but when I remove it I get the message BT is not available.

I'll keep doing more tests

I haven't been lazy today, here is version 2.3.0d2. I improved some details of the driver:

Changed SDK and deployment target to 10.11 in order to maintain compatibility with older versions of macOS. In case you are upgrading from an earlier version I posted here in the thread during the last days, please make sure to replace all kexts with the new ones (BrcmPatchRAM3.kext, BrcmFirmwareRepo.kext or BrcmFirmwareData.kext, BrcmBluetoothInjector.kext).

+1 for you, Sir. Another DW1830 BT module working on Catalina, now with correct firmware loaded. Thank you for picking this up from @Rehabman and continuing with great work.

Visioner · October 10, 2019

Thank you!
I have some trouble. I put (BrcmPatchRAM3.kext, BrcmFirmwareRepo.kext, BrcmBluetoothInjector.kext) to /L/E and sudo kextcache -i /
And if I load this kext:
sudo kextutil -v 5 /Library/Extensions/BrcmBluetoothInjector.kext

sudo kextutil -v 5 /Library/Extensions/BrcmFirmwareRepo.kext

sudo kextutil -v 5 /Library/Extensions/BrcmPatchRAM3.kext

then log show --predicate 'processID==0' --last 10m | grep BrcmPatch

And also I have stuck when I booting the OS. If I remove this bluetooth kexts my MacOS booting without problem.

These kexts upload firmware to the BT controller and make it known to the OS, nothing more, nothing less. What you are describing sounds more like a problem with Catalina's BT stack than a driver issue.

If you want more information, use the debug versions of the kexts and boot with boot flag -v to see what's going on. It might also be an USB related issue. Anyway, without detailed debug output, a diagnosis is almost impossible.

EDIT1

sorry. not sure this file newest firmware. it just shown v5820 more high than your driver default Firmware verison.

EDIT2.

uploaded firmware file is for win7.

sorry for confusion. your driver is lastest driver.

These kexts upload firmware to the BT controller and make it known to the OS, nothing more, nothing less. What you are describing sounds more like a problem with Catalina's BT stack than a driver issue.

Speaking of problem with Catalina's BT stack, woke up this AM to a KP and a restarted system. According to the report details, the offender was the BT stack. I'll give a shot with the debug version and see if I catch anything on it, but wanted to give heads up.

FammasMaz · October 11, 2019

So I just have to move the Kext files into the Others Folder in clover? No need to remove the files in L/E put there by Rehabman's hot patch and rebuild the kernel cache?

If you want more information, use the debug versions of the kexts and boot with boot flag -v to see what's going on. It might also be an USB related issue. Anyway, without detailed debug output, a diagnosis is almost impossible.

Thank you, the issue with the booting was due to USB. Apparently, I incorrectly implemented USBPorts.kext. I returned back to USBInjectAll.kext and booting without an issue using your bluetooth kexts. There are no sleep problems either.
There was a problem with the headphones do not connect with the AptX codec, but I found sad information:

Quote

For those still looking, it appears that aptX support has been silently removed from macOS Catalina (10.15); even in the public release.

I haven't been lazy today, here is version 2.3.0d2. I improved some details of the driver:

Changed SDK and deployment target to 10.11 in order to maintain compatibility with older versions of macOS. In case you are upgrading from an earlier version I posted here in the thread during the last days, please make sure to replace all kexts with the new ones (BrcmPatchRAM3.kext, BrcmFirmwareRepo.kext or BrcmFirmwareData.kext, BrcmBluetoothInjector.kext). Mixing kexts of different versions won't work.

Improved error handling so that the driver better recovers from error conditions during firmware upgrade.

Good luck testing!

BrcmPatchRAM3-V2.3.0d2.zip

I can confirm it's working for me too!

I have RAM3,Repo and Injector in /L/E .. rebuilded kernel cache and got Bluetooth again!

Thanks

Good day! These kext work in my system. But the sound in the AirPods starts interrupted, then stops altogether. Can you check it out? The kexts are set to L/E.

Hi, guys.

Having troubles getting BT working also.

Im on HP Elitebook 840 G5/ bcm94352z. Fallowed RehabMan guide to freshly install Catalina.

Everything is working except BT and Web-camera.

Any help?

Tried Mieze's kexts in L/E.

1. sudo kextcache -i /

2. Reboot

3. log show --predicate 'processID==0' --last 10m | grep BrcmPatch - NOTHING

4. sudo kextutil -v 5 /Library/Extensions/BrcmPatchRAM3.kext - LOG in annex

kext rejected... means you need to install them properly

How can I install them properly?

I mean, what steps do I need to follow.

-----------

UPDATE

-----------

Got it working.

Followed this tutorial for installation - https://www.tonymacx86.com/threads/guide-installing-3rd-party-kexts-el-capitan-sierra-high-sierra-mojave-catalina.268964/

And used Mieze's (BrcmBluetoothInjector.kext BrcmPatchRAM3.kext BrcmFirmwareData.kext)

1. Disable gatekeeper

2. Install

3. Reboot.

BT is working fine. Thanks.

~~P.S There is still problem with WebCamera. System can't locate the hardware. If someone has some tip, will be appreciated.~~ Solved

Here is version 2.3.0d3 in which I optimized a few details and fixed some possible weaknesses of earlier versions. It's working 100% stable on my test machines and I consider it to be ready for productive use.

Have fun!

Version 2.3.0d3 is now working fine for me on Catalina and Dell Wireless 1830 Bluetooth 4.1 LE (detected as BCM920703). Thank you!

Here is version 2.3.0d3 in which I optimized a few details and fixed some possible weaknesses of earlier versions. It's working 100% stable on my test machines and I consider it to be ready for productive use.

Have fun!

Good day! Still in the first 10 seconds the sound stutters in the airpods, then disappears altogether. System established with zero. Can be any data need? I am ready to provide.

Hi, guys.

Having troubles getting BT working also.

Im on HP Elitebook 840 G5/ bcm94352z. Fallowed RehabMan guide to freshly install Catalina.

Everything is working except BT and Web-camera.

Any help?

Tried Mieze's kexts in L/E.

1. sudo kextcache -i /

2. Reboot

3. log show --predicate 'processID==0' --last 10m | grep BrcmPatch - NOTHING

4. sudo kextutil -v 5 /Library/Extensions/BrcmPatchRAM3.kext - LOG in annex

btLOG

For HP Laptop not need the RAM3

I am using only BrcmBluetoothInjector.kext, BrcmFirmwareData.kext and thats working perfect on HP ProBook 6570b

EDIT ****

kexts Inject by Clover
