Restoring through a computer connected through USB, is only needed if resetting on the device itself is not accessible (e.g. when the device doesn’t start up properly).
↳ The Apple TV (3rd generation) [A1427 or A1469] needs to be powered at the indicated moment (step 4).
↳ The USB cable needs to support generic data transfer. Not all do that. Some bundled USB cables are customized for a certain device only, or are for charging or power only.
The Apple Configurator app is normally not needed for resetting or restoring. Although it can be helpful if it reports that “Activation failed” [253315520 by RKG61]. Activation with an Apple ID is a requirement for AirPlay support.
Now it’s not working the AirPlay.
Note that AirPlay support differs by content or app. Not everything can be streamed using AirPlay.
Please see the content provider’s website for their listed system requirement for AirPlay.
- Some services block AirPlay support (e.g. Netflix and certain pay TV providers).
- Some services make no effort to make their content AirPlay compatible.
- Some services require a receiving device that supports AirPlay 2 — which Apple TV (3rd generation) does not qualify for.
- Some services support AirPlay for their mobile app, but not from a website on a Mac.
- Services and apps can change their system requirements at any time. Supporting Apple TV (3rd generation) is extra work for them, and with diminishing numbers of this device model, it may no longer be worth the effort for some companies.
