The Pangu Team has just released a jailbreak for the new Apple TV. The jailbreak is limited to Apple TV 4 running tvOS 9.0 and 9.0.1.
So we just release jb for ATV4. Checkout at http://pangu.io . Current jb will give u ssh access to ATV4 with tvOS 9.0/9.0.1
Jailbreak developers may port their tweaks and apps to ATV with ssh available. Check the guide before jailbreaking your ATV.
ATV4 requires arm64 binaries!
The jailbreak tool can be downloaded from pangu.io.
If you’re still on tvOS 9.o or 9.0.1, keep away from tvOS 9.1, 9.1.1 and 9.2 software updates, as those are not supported by the Pangu’s jailbreak and it is impossible to downgrade the firmware to a previous version.
As the Pangu Team admits, the jailbreak is mostly targeted (at least for now) for jailbreak developers, so they can start releasing tweaks and apps for the Apple TV 4.
Apple Developer Program membership is required in order to perform the jailbreak.
As for now, the Pangu 1.0 Apple TV jailbreak tool anly allows SSH access.
