Note: A firmware update is only needed if you're unable to connect to the pin with your iPhone. Only a few user are affected by this problem so make sure you're are one of them. 

What you'll need

  • The pin can only be updated via Bluetooth so you'll need access to a device that can connect to the pin (ie an Android device).
  • Your pin (charged).
  • If you're inexperienced with Android it's also good if you have a Android user that can help you.
