Broadcom BCM4352 HMB 5gz Wireless+BT 4.0  (AzureWave AW-CE123H) on Yosemite 10.10.1

For those with issues surrounding handoff support and 5gz using US country code you want to do the following:
 
1) download and install BTFirmwareUploader_v2.6_Final.zip

2) download and run wireless_bcm94352-100_patch.command.zip

a. Select 1 (for Handoff only)

 enter password

3) Copy the kext "IO80211Family.kext" from System/Library/Extensions to Desktop
4) Go to folder: IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/Contents/MacOS/ and  Open the "AirPortBrcm4360" in hexfiend app
5) Press Command + F to search
6) Enter the following hex codes in Find and replace box

a) Find: 6B 10 00 00 75 0D   Replace: 6B 10 00 00 90 90  (for Cosmetic Fix "Unknown -> AirPort " )

 Find: 58 54 00 2B 18 2C 21 00 20  Replace: 55 53 08 0A 36 1C 47 00 0A (for 5 GHz Fix for BCM94352HMB with US country) - NOTE: This is the same as using this: sudo perl -pi -e 's|\x58\x54\x00\x2B\x18\x2C\x21\x00\x20|\x55\x53\x08\x0A\x36\x1C\x47\x00\x0A|g'/System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/Contents/MacOS/AirPortBrcm4360

7) Save, Close & Install the kext.

8) Open Terminal and run the following: sudo touch /System/Library/Extensions/
9) Repair Disk Permissions

10) Restart

 

OTHER NOTES: I found that it didn't make any difference to make the following patch to the kext "AirPortBrcm4360.kext" located at System/Library/Extensions/IO80211Family.kext/Contents/Plugins/ using: 

 

<key>IONameMatch</key>

<array>

<string>pci14e4,43b1</string>

<string>pci14e4,43a0</string>

</array>

 

So I just left it out. Works the same without it.
