Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)将所有电线脱离apple tv
Connect the micro USB cable to the Apple TV and to your computer.将MICRO USB分别连接至你的Apple TV及你的电脑
Reconnect the power cable (only for Apple TV 3)重新连接电源线
Open iTunes.打开iTunes
Select your Apple TV in the Devices list, and then click Restore.在你的设备列表中找到Apple Tv选项，然后点“恢复”按键
望采纳 谢谢
