Updating jailbreak 2 1 to 2 2
Unfortunately, it’s the only viable option unless you want to try something that’s not been properly tested by a large group of experts.It’s not the most elegant jailbreak, if you’ve seen the older version, but the latest update has a nice, intuitive UI and it’s as stable as you’re going to get for now.On first boot, the device will not be running a patched kernel.However, rather than having to run a tool from a computer to apply the kernel patches, the user is able to re-jailbreak their device with the help of an app (usually sideloaded using Cydia Impactor) running on their device.A device with a tethered jailbreak is able to boot up with the help of a jailbreaking tool because the tool executes exploits via USB that bypass parts of that "chain of trust", bootstrapping to a pwned (no signature check) i BSS, i BEC, or i Boot to finish the boot process.Untethered or semi-untethered jailbreaks are shown with a green 'yes'.He’s reportedly working on it, but there’s no firm ETA for now.So, that means you can still jailbreak a qualifying 64-bit device with Liberi OS, but you’ll have to wait for Cydia and Substrate to come through from Saurik.
A semi-untethered jailbreak gives the ability to start the device on it's own. 2017 was a shitty year for i OS jailbreaks, no doubt.A big disappointment by Team Pangu followed by some hope from Luca Todesco and a few others, but really nothing that the average i OS jailbreak enthusiast could reasonably work with, without risking their i Phone being bricked and forced to upgrade to a signed i OS version. Late in December 2017 Jonathan Levin authored the Liberi OS jailbreak for i OS 11 – i OS 11.1.2, and even followed it up quickly with an updated version that fixed certain issues on the previous one.If the user turns the device off and then boots it back up without the help of a jailbreak tool, the device will no longer be running a patched kernel, and it may get stuck in a partially started state, such as Recovery Mode.In order for the device to start completely and with a patched kernel, it must be "re-jailbroken" with a computer (using the "boot tethered" feature of a tool) each time it is turned on.

All changes to the files on the device (such as installed package files or edited system files) will persist between reboots, including changes that can only function if the device is jailbroken (such as installed package files).
