The palera1n checkm8 bootrom exploit-based jailbreak tool for A9-A11 chip-equipped iPhones and iPads running iOS or iPadOS 15 or 16 has piqued substantial interest, as it’s currently the only publicly available jailbreak tool for the aforementioned device and firmware combinations. But it’s worth noting that the tool is currently intended for developers and is fully Terminal-based, as made evident in our step-by-step tutorial.
How to run a network speed test from the macOS Terminal window

Which tool should I use to jailbreak iOS 5.1.1?
With iOS 5.1.1, there's no shortage of tools available to perform an untethered jailbreak. In fact, there's so much saturation from a tool perspective, that it can be a little difficult to discern which tool to use.
Inside, we'll briefly cover some of the tools available, and some of the popular scenarios where certain tools fare better than others.
iPhone Dev Team releases CLI tool for Rocky Racoon 5.1.1 Untether
The iPhone Dev Team has released a command line interface tool (CLI) as an alternative for the Absinthe 2.0 untethered iOS 5.1.1 jailbreak. The CLI tool is capable of performing the exact same jailbreak that can be accomplished with Absinthe 2.0, but the difference is that it's completely command line based.
The CLI tool is for more advanced users who prefer to have more control over the jailbreak process. We recommend that you stick with the Absinthe 2.0 GUI tool, but it's nice to know that a CLI tool exists if you happen to be a more advanced user.
If you can remember, the Dev Team provided a CLI tool as an alternative to the previous version of Absinthe for the iOS 5.0.1 untethered jailbreak as well. It's safe to assume that you can expect a similar experience to that of the previous CLI release.
