Step 4:When prompted, connect your Apple TV using a micro-USB cable (leave power disconnected).
Once the light on the front of the AppleTV begins to flash rapidly, point the remote at the AppleTV and hold both the MENU and PLAY/PAUSE buttons for 7 seven seconds.
Note: This step will require the silver (aluminum) AppleTV remote that was included with the ATV2. The older, white (plastic) remotes will not work.
