What is checkra1n?
Based on the infamous checkm8 exploit, checkra1n is a semi-tethered jailbreak tool designed for iOS 14. It is developed by Luca Todesco and the rest of the Kim Jong Cracks team.
The latest build brings support for iOS 14.0 as well as tvOS 14.0. However, support for newer devices seems to be limited at the moment. Only iPhone and iPad models with the A9/A9X chip are compatible at the moment.
Nevertheless, the developer team is working on adding support for iPhone 7, 7 plus, and other devices.
On the other hand, iPhone models with the A11 Bionic chip – iPhone 8, 8 Plus, and X – will be addressed in a future update.
The reason being that Apple uses a new mitigation technique in SEPOS on devices with the A10 chip and above. For instance, if you boot an iPhone in DFU mode and the SEP (Secure Enclave Processor) gets a request to decrypt user data, it causes a kernel panic.
While checkm8 is a powerful BootROM exploit, it does not affect the SEP. However, things have changed with the release of the blackbird vulnerability, which allows an attacker to access the SEP. If all goes well, an update for A11 devices will go live soon.
Apart from iOS devices, checkra1n also supports the bridgeOS operating system of Apple’s T2 security chip.
Jailbreaking Apple’s security chip will be of little use for the average user, however.
- Refrain from using beta releases on your primary device. Beta and alpha builds should only be used on spare devices.
- Users with A11 devices running iOS 14.0 or higher firmware must remove the passcode and enable the “Skip A11 BPR check” option.

- A11 update: The patched version has now been updated for A11 devices. To use this tool, run bspatch in Terminal with the aforementioned patch file and the checkra1n binary. This is only meant for advanced users and testing purposes.
- Patched version: This is an unofficial build released with support for A10 devices by Exploit3d. Run it in CLI (Command Line Interface) with the -c flag like so – ./checkra1n_patch -c. Remember, passcode and encryption features will not work after jailbreaking. SEP will fail to decrypt user data should you enable the passcode. So, we suggest using it on test devices only.
