MatchOS: 10.13.x
Name: com.apple.driver.AirPort.BrcmNIC

Replace: <66C70623 61EB348D 55D0>


Just change 23 61 to your country. Mine is 42 52 for BR.
The default (#a) is a generic one.

There is now another tool for those who needs the country code change on Mac OS X.
It is called AirportBrcmFixup.kext.
This Kext is a Lilu plugin and MUST be installed with latest Lilu.kext.
Country Code change can be done using a boot parameter: brcmfx-country=XX
Using this kext, we don't need to use fcvo, 5Ghz, and Airport Extreme or even FakePCIID + FakePCIID_Broadcom_WiFi.
PS: don't forget to use -lilubeta and -brcmfxbeta on High Sierra.
Features

• Supports AirPort_Brcm4360, AirPort_BrcmNIC and AirPort_BrcmNIC_MFG
• Implements patch for passing chip id checking (fcvo - 0xaa52)
• Implements patch for "Failed PCIe configuration"
• Implements patch for "Third-Party Wireless Card" (returns vendor name "Apple")
• Implements patch for removing of white-list check
• Implements 5Ghz and country code patch (US by default)
• Boot-arg "brcmfx-country=XX" changes the country code to XX (US, CN, ...)
• Boot-arg "-brcmfxdbg" turns on debugging output
• Boot-arg "-brcmfxbeta" enables loading on unsupported osx
• Boot-arg "-brcmfxoff" disables kext loading

All these Lilu.kext Plugins are really nice to fix most of the stuff with much ease than kext to kernel patches but i always prefer config.plist patches over kext installations,they do seem to be much cleaner to me,less failing to load chances,etc.

Thanks for the post,this should be very useful for many people there.
