is a semi-tethered jailbreak based on the "checkm8" bootrom exploit. Unlike software-based exploits that Apple can patch with an iOS update, checkm8 is a hardware-level vulnerability (present in the A5 through A11 chips). This makes it permanent and unpatchable by Apple.
: While jailbreaking is generally safe, it is highly recommended to backup your device before starting.
: Compatible with A7 through A11 chips (iPhone 5s, 6, 7, 8, and X). | Issue | Solution | |-------|----------| | Tool
