Galaxy Player 5: How to Change your MAC address

I recently wrote some code that taught me a lot about how wifi mac address work in the Android world. I suspect that most people are not aware that they can change their mac address to whatever they want. So I thought I'd write some simple instructions on how to do it for the Galaxy Player 5.

Prerequisites


  1. Good file manager app. ( I use ROM Toolbox )
  2. Good text editor app. ( I use ROM Toolbox )
  3. Make sure that /system is writeable. You may need to manually remount system rw:
    1. In terminal app: 
      1. su
      2. mount -o remount,rw /system
    2. Using ADB
      1. adb root
      2. adb remount


If you're on a recent KitKat build, such as Beanstalk 4.4+ then:


  1. Use the file manager to browse to the file /efs/imei/.nvmac.info and open it with a text editor.
  2. Inside you will find your mac address, change it to any valid mach address you like.
  3. Save
  4. Reboot.


If you're on an old KitKat build or an older incarnation of Android then:

  1. Use the file manager to browse to the file /system/vendor/firmware/nvram_net.txt and open it with a text editor.
  2. Scroll down till you see a line that starts with macaddr=
  3. What follows is your wifi mac, change it to any valid mac address.
  4. Save.
  5. Reboot.
