Unlike traditional jailbreaks that run as apps on your iPhone, checkn1x runs on your computer. It turns your PC into a dedicated jailbreaking kiosk.

Checkn1x-1.0.6-amd64.iso is a lightweight Linux-based ISO designed to provide a fast and reliable environment for running the Checkra1n jailbreak

The checkra1n jailbreak is "semi-tethered," meaning if your device restarts, the jailbreak will be disabled, and you will need to use the checkn1x USB again to re-enable it.
