Once successful, you will read the message “You are now a developer!”.

Open ‘Developer options’ > ‘Modem Interface’ > Switch from ‘USB’ to ‘UART (for debug only).  Proceed to restart the device in order for the change to take effect.  Once rebooted, you can connect your device to a external computer via USB (you may have to swipe down the notification centre, and tap on ‘USB for charging’ > change to ‘File transfers’.
