Change Mac Adress permanently CM12 // Xperia Z2 Castor Windy maybe other Sony devices topic

Hi,

after CM 12 my Z2 Castor Windy becomes the same MAC Adress like my Z3.

So how to change the MacAdress of my Z2 Castor Windy permanently?

Tried to google for it but found only solutions for KitKat that dont work.

And here is the Solution for CM12/maybe other CustomROMs that changes MAC Adress at flashing:

1. Use a Root Explorer/Root Filemanager
2. Go to: /data/etc/wlan_macaddr0
3. Open it and read out your old MAC from Sony - write it down.
4. Go to: /system/etc/firmware/wlan/bcmdhd/bcmdhd.cal and open it writeable
5. Edit Line 8 macaddr=xx:xx:xx:xx:xx:xx to your original MAC from Sony.
6. Save changes and reboot.
7. DONE - enjoy - you will have your old MAC Adress permanently.
