Once DFU mode is detected, checkn1x will inject the exploit. Your device screen will flash with code text, and the computer will show "All Done".
If you are verifying the file to ensure it hasn't been tampered with, you should check its checksum. However, official checksums for older ISOs are sometimes difficult to locate on the official site as newer versions replace them. Generally, you should only download this file from the official checkra1n website to ensure safety.
This is a known issue with checkn1x 1.1.7 and certain device/iOS combinations. For version 1.0.6 (using checkra1n 0.9.8), fewer issues are reported, but if encountered:
iPhone 5s, 6, 6 Plus, 6s, 6s Plus, SE (1st Gen), 7, 7 Plus, 8, 8 Plus, and iPhone X. checkn1x-1.0.6-amd64.iso
in the checkn1x environment:
Because the official checkra1n application was only natively compiled for macOS and Linux, Windows users lacked a straightforward method to utilize the historic checkm8 BootROM exploit. The checkn1x project solved this by packing a stripped-down Linux distribution (typically under 100MB) directly into an ISO file. This allows any 64-bit AMD or Intel computer to boot into a dedicated jailbreak environment without modifying the host operating system.

To use the checkn1x-1.0.6-amd64.iso image safely and successfully, ensure you have the following: Must feature a 64-bit processor.
This flexibility is what makes the checkn1x ecosystem so powerful—developers can compile customized ISO images for specific device types or incorporate experimental checkra1n builds.

Checkra1n should detect your device. If it says "Unsupported iOS version" or similar, you may need to go to and select "Allow untested iOS/iPadOS/tvOS versions" .
This version typically brings updated versions of checkra1n, ensuring compatibility with newer iOS versions and improved bug fixes.

is a lightweight Linux-based bootable image designed specifically to facilitate the checkra1n jailbreak on Windows and Linux PCs. Because the checkra1n tool was originally built only for macOS, developers created checkn1x as a specialized "live" operating system that allows users to run the jailbreak directly from a USB flash drive. What is it?
The release of represents a significant milestone in the intersection of mobile security research and open-source utility. As a lightweight, Linux-based "Live CD" environment, its primary purpose is to facilitate the execution of the checkra1n jailbreak on compatible iOS devices. By stripping away the overhead of a full operating system, version 1.0.6 offers a streamlined, portable solution for users who lack access to macOS or a permanent Linux installation.
