Semi-Tethered: Every time you reboot your iPhone, the jailbreak is disabled. You must use the bootable USB drive and a PC to re-jailbreak to restore your tweaks. How the "Windows Zip" Works

Device Compatibility: Supports A7 to A11 chip devices, including iPhone 5S through iPhone X.
iOS Support: Specifically updated to support iOS 14.8, 14.7.1, and older versions like iOS 12.5.5.
Critical Fixes: Includes a hotfix for A9X devices (like certain iPad Pro models) that previously failed to boot on iOS 14.5.
