“Bricked” is a term used to describe a piece of hardware that is completely non-functional because the firmware has either not been loaded, become corrupted in some way, or halted because of a bug. That is, it’s as useful as a “brick”.
In all cases, it’s now necessary to reload the firmware to get the board running again.
Since there is no Device Firmware Upgrade (DFU) present or usable, the reload, or “unbricking” process requires the use of another utility that uses the board’s COM port.
