Is there a user control on the device to restore it? If not then it is bricked to that user. Bricked is relative to the users ability to fix it. At some level of skill and money nothing is "bricked" since you could replace or reflash anything.
Almost all usage for bricked from before it become a mainstream word was meaning that the bootloader on a device had become overwritten or corrupt meaning it is no longer possible to fix using the usual firmware flash method.
This is still fixable if you knew how to access the flash chip directly and had a backup of its content.
Never have I seen bricked strictly mean that hardware has blown up.
