Yes, but like most of these "provisions" it assumes that the device is working to be able to set/enter that "maintenance mode", so it is really a "maintenance mode" as opposed to a "repair mode".
If you have a broken (black) screen or touch not working or if the device doesn't boot properly it is useless.
