A checkm8 vulnerable iOS device on iOS 15 or 16 (A8-A11)
The device must be on iOS 15.0-16.2
Linux or macOS computer
Python 3 must be installed.
palera1n is a work-in-progress jailbreak script that patches the kernel so you can use Sileo and install tweaks. Currently, palera1n is compatible with A11 (iPhone X) and earlier devices on iOS 15 and later, with some major caveats.
On A10(X) and A11 devices, you must disable your passcode and will not be able to use your passcode, or other SEP functionality, until you boot into a stock iOS state. SEP functionality includes things such as a passcode, Face ID/Touch ID, and Apple Pay.
Additionally, if you are on iOS 16 and have ever set a passcode, you will need to erase all content and settings in order to be able to jailbreak.
If you are not using the semi-tethered flag, this is a tethered jailbreak, which means the device must be booted using a computer every time, otherwise it won’t boot at all.
However, this (and the semi-tether as well) can be easily reverted by following Removing palera1n.
