Checkm8 is an attached iOS exploitation tool that requires you to boot your iPhone after each restart. It is the main component of the Checkra1n Jailbreak tool and, most importantly, it is a jailbreak exploit for life and Apple cannot patch it with iOS updates. This error was fixed only in the last hardware update.

What else can you achieve with Checkm8 exploit? Reduce or upgrade to any jailbreakable iOS version without SHSH support, Checkm8 supports dual boot (the device can be started on Android) and will work with all the next versions of iOS released by Apple. A computer is required to Jailbreak.

In addition, first-generation Apple Watch and Series 1, 2 and 3 are vulnerable to the operation of Checkm8. The Checkra1n tool can also skip DRM mechanisms in the Jailbreak detection application. Recently there is news that Checkra1n is also compatible with Apple TV (1st, 2nd, 3rd and 4th generation) on tvOS 13.

The new Jailbreak tool was made possible by well-known collaborators of the Jailbreak community such as ih8sn0w, jonseals, pshycotea, qwertyoruiop, nullpixel, xerub, sigza, aregp, axi0mx and others. Checkra1n Jailbreak will allow you to install any package manager (Cydia, Zebra, Sileo, etc.).

Checkra1n Jailbreak Tool uses Cydia Substrate, the powerful code modification platform behind Cydia. Substrate facilitates software modification, even without the source code. From the Cydia package manager you can install settings, hacks, libraries and applications from the so-called repositories.
