Commands the gimbal to erase its firmware image and flash configuration, leaving only the bootloader. The gimbal will then reboot into the bootloader,

new firmware image is loaded, and will cause all tuning parameters to return to their factory defaults. WARNING: sending this command will render a
gimbal inoperable until a new firmware image is loaded onto it. For this reason, a particular "knock" value must be sent for the command to take effect.
