Changelog

1.0.2:

• Latest release (just got this stub filled out, apologies for lack of proper change log)

Install instructions without iTunes (OTA Updates)

WARNING: 12.4 is still signing for AppleTV HD and 4K, but once this signing window closes you do NOT want to follow these instructions anymore

NOTE: This reverts your AppleTV to the snapshot created right before you jailbroke your device. This should enable you to do an OTA update successfully, or even to use something like idevicerestore to perform an update install rather an a restore install.

Step 1: Make sure nitoTV and related components are up to date
Step 2: Install Snappy (available in utilities featured section or via package identifier com.bingner.snappy)
Step 3: SSH in to your Device (ssh root@DEVICE_IP)
Step 4: snappy -o
Step 5: reboot
Step 6: Perform an OTA update (ONLY IF 12.4 or the latest signing version is vulnerable, otherwise DO NO DO THIS IF YOU WANT TO KEEP YOUR JAILBREAK)

Install Instructions for AppleTV 4

Step 1: Download chimeraTV.ipa

Step 2: Plug your 4th generation AppleTV into your computer via a USB-C cable

Step 3: Make sure you have a developer account with apple, you can get one for free (your on your own to figure that out!)

Step 4: Download Cydia Impactor

Step 5: Drag the chimeraTV.ipa into Cydia Impactor

Step 6: Click start

You will almost definitely get some error related to plist files, i dont remember the exact error, this error is fine and expected behavior (it happened every time for me) check your AppleTV to see if its installed

Step 7: Run chimeraTV and hit the 'Jailbreak' button it should work on the first try! Hit the respring button when prompted to. Once two respring's have occurred nitoTV should launch automatically!

Future Restore Instructions

Preparation

You will need 11.x/12.x blobs saved for your 4th generation AppleTV. If you do not have those, you cannot restore to 11.x/12.x. 11.2.x can no longer be installed because there aren't any SEP versions that are still signing that are compatible. These directions are mac specific but with minor changes should work on any comp.

Step 1: Download futurerestore for your respective computer, here are the latest builds that work futurerestore_macos

Step 2: Download target version 11.x versions or 12.x versions

Step 3: Create a folder and put target ipsw inside

Step 4: Open your terminal app (mac os, linux and windows you are on your own here)

Step 7: cd to the directory you created with futurerestore, and the target ipsw.

Step 8: find your SHSH blob and look for the 'generator' inside of it, make a note of this value.

Step 9: Enter your nonce from the SHSH file (generator)

Step 10: Click the 'Jailbreak' button it should work on the first try! Hit the respring button when prompted to. Upon respringing SSH into your AppleTV

Step 11: ssh into your device (ie 'ssh root@apple-tv.local') default password is alpine

Step 12: run this command

 nvram auto-boot=false

Step 13: run this command

Step 14: from the directory in the terminal with your future restore files run the following command (with your file names substituted in place)
