How do I jailbreak the Apple TV 4th-generation?
The Apple TV 4th-generation can now be jailbroken. Devices running tvOS versions 9.1-10.1 are supported by the jailbreak tool LiberTV.
After the Apple TV is connected via USB to a computer, the LiberTV app can be installed using Cydia Impactor. Running the LiberTV app jailbreaks the device.
Note that the Cydia app store has not been released for the Apple TV, and NitoTV will cause problems with tvOS 10-10.1. Jailbreaking the Apple TV is recommended for advanced users and developers only.
At this time tvOS 10.1.1-10.2 cannot be jailbroken.
