A brick (or bricked device) is a mobile device, game console, router, computer or other consumer electronic device that is no longer functional due to corrupted firmware, a hardware problem, or other damage. The term analogizes the device to a brick's modern technological usefulness. Bricking a device is most often a result of interrupting an attempt to update the device. Many devices have an update procedure which must not be interrupted before completion; if interrupted by a power failure, user intervention, or any other reason, the existing firmware may be partially overwritten and unusable. The risk of corruption can be minimized by taking all possible precautions against interruption.

Hard bricked devices generally show few or no signs of life. A hard bricked device does not power on or show any vendor logo; the screen remains turned off or blank. Some of the major reasons for hard bricking include installing firmware not intended for the device, severe physical damage, interrupting a firmware flashing procedure, or following a flashing procedure incorrectly.
