Usage: $0 [Options] [ subcommand | iOS version ]
iOS 15.0-16.3.1 jailbreak tool for checkm8 devices

Options:
    --help              Print this help
    --tweaks            Enable tweaks
    --semi-tethered     When used with --tweaks, make the jailbreak semi-tethered instead of tethered
    --dfuhelper         A helper to help get A11 devices into DFU mode from recovery mode
    --skip-fakefs       Don't create the fakefs even if --semi-tethered is specified
    --no-baseband       Indicate that the device does not have a baseband
    --restorerootfs     Remove the jailbreak (Actually more than restore rootfs)
    --debug             Debug the script
    --china             Enable Mainland China specific workarounds (启用对中国大陆网络环境的替代办法)
    --ipsw              Specify a custom IPSW to use
    --serial            Enable serial output on the device (only needed for testing with a serial cable)

Subcommands:
    dfuhelper           An alias for --dfuhelper
    clean               Deletes the created boot files

The iOS version argument should be the iOS version of your device.
It is required when starting from DFU mode.
