Installing the initial firmware
Plug in the USB cable to your USB adapter, whilst holding pressure down on the pins to make sure they make good contact. If you have a 1 or a 3 button switch, make sure you are pressing and holding the middle button in order to enter flashing mode before you plug in the USB cable to your computer. Wait 3-4 seconds and then you can release the button if you are pressing it, but make sure to keep constant pressure on the pins – it may be easier to have someone help you do this.
