Usage: idevicerestore [OPTIONS] PATH
Restore IPSW firmware at PATH to an iOS device.

PATH can be a compressed .ipsw file or a directory containing all files
extracted from an IPSW.

Options:
 -i, --ecid ECID  Target specific device by its ECID
                  e.g. 0xaabb123456 (hex) or 1234567890 (decimal)
 -u, --udid UDID  Target specific device by its device UDID
                  NOTE: only works with devices in normal mode.
 -l, --latest     Use latest available firmware (with download on demand).
                  Before performing any action it will interactively ask to
                  select one of the currently signed firmware versions,
                  unless -y has been given too.
                  The PATH argument is ignored when using this option.
                  DO NOT USE if you need to preserve the baseband (unlock)!
                  USE WITH CARE if you want to keep a jailbreakable firmware!
 -e, --erase      Perform a full restore, erasing all data (defaults to update)
                  DO NOT USE if you want to preserve user data on the device!
 -y, --no-input   Non-interactive mode, do not ask for any input.
                  WARNING: This will disable certain checks/prompts that are
                  supposed to prevent DATA LOSS. Use with caution.
 -n, --no-action  Do not perform any restore action. If combined with -l option
                  the on-demand ipsw download is performed before exiting.
 -h, --help       Prints this usage information
 -C, --cache-path DIR  Use specified directory for caching extracted or other
                  reused files.
 -d, --debug      Enable communication debugging

Advanced/experimental options:
 -c, --custom     Restore with a custom firmware
 -s, --cydia      Use Cydia's signature service instead of Apple's
 -x, --exclude    Exclude nor/baseband upgrade
 -t, --shsh       Fetch TSS record and save to .shsh file, then exit
 -k, --keep-pers  Write personalized components to files for debugging
 -p, --pwn        Put device in pwned DFU mode and exit (limera1n devices only)
