If you have a newer device, such as an iPhone XS or newer, you will not be able to use checkra1n. Check the Device Selection page to check if your device is compatible.

checkra1n is currently only compatible with macOS & Linux. You are currently not running a macOS or Linux device and checkra1n will not work on your system. You can use bootra1n instead.

checkra1n is a semi-tethered jailbreak, meaning it requires a PC to re-apply the exploit after a reboot. Click the link to learn more.

checkra1n is capable of jailbreaking nearly every iOS device on firmwares 12.3 and above. It’s currently only compatible with macOS and Linux but a Windows release is coming soon.

Once the exploit is installed, you will have the choice of installing a package manager. For this we will be using Cydia. You may already be familiar with Cydia, as it has been the default package manager for over a decade.
