Jonathan Levin has twittered his new jailbreak tool for Apple tvOS called LiberTV, and now liberating TvOS 11.0 and 11.1 on the ATV 4 and 4K:
Before you get started:
Make sure to get the only ipa at this link.
Also:
This jailbreak is compatible with TvOS Version 11.0 or 11.1.
1. Sideloading
The LiberTV.ipa is an unsigned binary. This means you have to sign it yourself. You have two options at the moment:
Apple's codesign(1)
Cydia Impactor
Here's the download link of LiberTV11
The latter is actually easier to use. Grab the IPA , and then sign it with your AppleID. You are now ready to sideload. Doing so requires XCode, and is performed thus:
XCode "Window" → Devices & Simulators (also accessible by ⇧ ⌘ 2) gets you to here:
You select the LiberTV.ipa like so:
And let it load. Congratulations. You're ready to run
2. Running
This is foolproof: only one button, no options.
If it runs correctly, you will get a note saying you can exit the app. So you can exit the app. (If you experience weird behavior, just background the app rather than exiting - it won't take any CPU anyway but will keep the process lineage intact)
3. SSH
Give LiberTV a couple of seconds AFTER the note to complete and set up the code signing bypass, and you can ssh to yourself - either over USB-C or (in the case of the 4k) over TCP/IP. You have a different IP address than shown here:
As the screenshot shows, merely setting the path automatically gets you all the binpack (and some fresh binaries at that).
To enable scp , you have to cp /jb/usr/bin/scp /usr/bin because that's done using a server side binary which must be in dropbear's path.
You can run any self signed binary you want, provided you sign it with the latest jtool - jtool --sign platform --ent plat.ent --inplace binary, with plat.ent being the same entitlements you get from jtool --ent on any of the binpack binaries - i.e. <platform-application> set to true.
4. If it works for you, you could choose to donate the developer. If it doesn't, you could visit this forum to report the problem.
