Checkra1n Jailbreak

Luca Todesco has finally released the highly anticipated jailbreak tool, checkra1n, for iOS 13.2 firmware and later. Here’s how you can download this tool and unlock your iPhone, iPad or iPod touch.

WHAT IS CHECKRA1N AND HOW DOES IT WORK?


Checkra1n is a semi-tied BootROM jailbreak tool developed for iOS 13 firmware. It is based on the checm8 exploit of axi0mX and developed by Luca Todesco, Jamie Bishop and the rest of the checkra1n development team.

Considered the most released jailbreak tool for modern firmware, checkra1n can jailbreak any firmware version as it exploits a vulnerability found in the device hardware.

Therefore, as long as Apple releases updates to your device, you can release it.

For example, the last exploitable device that can be released with this tool is the iPhone X.

Apple generally supports your mobile devices for five to six years before they stop sending updates. As a result, iPhone X will remain jailbroken until iOS 15 or 16.

The only way to patch the checkm8 exploit is to recover all affected devices and replace their SoC (system-on-chip), which is simply impossible to do at scale.

ADVANTAGES


In addition, checkra1n may allow you to make in-depth modifications (apart from jailbreak) such as:

  • Custom firmware flashing.
  • Update and downgrade without SHSH Blobs.
  • Dual-boot different iOS operating systems on the same device.
  • Engineer best detection of jailbreak DRM bypass utilities, etc.
  • Stable uptime compared to other tools.

DISADVANTAGES


Despite all its benefits, checkra1n does not have its flaws and defects:

  • Compatibility; It is a major problem for anyone who wants to use this tool on a modern device. checkra1n is not compatible with devices released after iPhone X (Bionic A11 chip) and will never offer support for them. Read the compatibility section carefully before attempting to unlock your device.
  • Re-jailbreak is an obstacle; checkra1n is a semi-tied utility and, as a result, requires you to connect to the computer whenever you want to start in a jailbreak state. If you restart your device without having access to a computer or laptop with jailbreak software, you will not be able to do so.
  • Operating system support; At the time of writing, support for this utility remains limited only for macOS users. If you have a Linux Windows, you can expect future updates or install Hackintosh. Running a MacOS virtual machine (virtual machine) on your computer or laptop using the virtual machine or other hypervisor software will NOT deliver the load correctly.
  • Cessation of updates; Apple may stop offering updates for affected devices completely to protect users. It seems exaggerated right now, but Apple could use this as a ploy to get users to buy newer (and more expensive) devices that are not vulnerable to exploiting checkm8.
