    Welcome to the recovery tool!
    The available options are:
    1) Reset device to factory state
    2) Reboot device
    3) Bootloader unlock [Current state: locked]
    4) Shell
    5) Try btrfs recovery if your device is in bootloop
    6) Exit
    Type the number of the desired action and press [Enter]:
    ALL DATA WILL BE ERASED! Clears everything from the device and reverts the
    software back to factory state. This means LOSING EVERYTHING you have added to
    the device (e.g. updates, apps, accounts, contacts, photos and other media).
