tvOS 10.1 jailbreak
tvOS 10.1 jailbreak could be on its way, says nitoTV

Prospective jailbreakers with Apple TV 4 are in for some exciting news as some tiny bits of yalu102 source code pointing to the fourth-gen Apple TV have recently surfaced via GitHub. If you are a fanatic who loves to decode info from semi-cryptic source code, you must be too keen on exploring the evidence that suggests tvOS 10.1 jailbreak for Apple TV 4 is just around the corner.

Here's why you may want to downgrade the firmware on your Apple TV 4 from tvOS 10.1.1 to tvOS 10.1:

Some tiny bits of source code found in yalu102 jailbreak for iOS 10.2 are invariably pointing to Apple TV, wherein a conditional statement within the yalu102 code pointing to "Apple TV5,3" is set to return a true value after execution. The code is also accompanied with a comment that states "Using Ian's condition, not having my Apple TV nearby."

The information deduced from the conditional code and the accompanying statement in the yalu102 source code further strengthens the claim that the tvOS 10.1 jailbreak for Apple TV 4 is imminent, if not almost certain. Check out the piece of yalu102 conditional code on the GitHub page that has been making waves on the internet:

else if (strstr(u.machine, "AppleTV5,3") && strstr(u.version, "root:xnu-3789.22.3~1/RELEASE_ARM64_S5L8960X")) { //Using Ian's condition, not having my AppleTV nearby tvOS 10.0.1 (14U71) @oncheh

In related news, renowned iOS researcher and Apple TV hacker, Kevin Bradley (aka nitoTV), has recently hinted at a probable tvOS 10.1 jailbreak being created from yalu102 for Apple TV 4. Here are some details he had recently posted on Tumblr to highlight the possibility of using yalu102 exploits for creating tvOS 10.1 jailbreak:

it should be compatible, i know offsets have been updated but from what i understand "The core exploit still relies on mach ports which tvOS doesn't expose to userland" Im not sure if any of this has changed in the last two days and havent had an opportunity to investigate yet.

With several pieces of the puzzle coming together, tvOS 10.1 jailbreak for Apple TV 4 looks like a definite possibility. Consequently, prospective Apple TV jailbreakers are advised to downgrade immediately to tvOS 10.1 from tvOS 10.1.1 as Apple is still signing the older firmware.

To accomplish this feat, you will need to plug-in your Apple TV to your computer using 'USB-C to USB-A' cable and then restore the firmware to tvOS 10.1 via iTunes.
