What does 'bricking' refer to in the context of IoT devices?

Bricking in the context of IoT devices refers to when a device becomes completely non-functional, often as a result of firmware or software updates that fail or are improperly implemented. This term derives from the idea that the device has become as useful as a brick, meaning it cannot perform its original functions or may not even turn on anymore.

When a device is "bricked," it typically loses its ability to operate, making it essentially unusable, which may stem from a failed update that corrupts the device's operating system or firmware. This is particularly concerning for IoT devices since they often rely on regular updates for security and functionality, and an error during this process can render them inoperable.

In contrast, enhancing device functionality relates to improving the performance or capabilities of a device, which does not align with the definition of bricking. Similarly, upgrading software and repairing damaged hardware focus on maintaining or improving functionality rather than disabling it. Bricking emphasizes the loss of function due to an unsuccessful update rather than any efforts to improve the device.
