I'm going to wade in and give the expired equine my lashing or two.
In the electronics industry, bricked carries the connotation of "non-recoverable failure", typically requiring component replacement, most often in a non-field-serviceable manner. This also is often in conjunction with some user-operation.
Examples:
- Error or power loss during a firmware upgrade that renders the device unstartable, including the routine to load new firmware. In this case you often have to resort to replacing the chip(s), as there's no way to get a working firmware image on to the device.
- Non-removable non-volatile storage failure. If you have solid state storage soldered on to the motherboard that goes bad. There's no "supported" method for replaceingg the storage.
- Permanent battery damage. Operating a device's rechargeable cell outside it's parameters such that it no longer accepts a charge. This typically implies a cell/pack not designed for temporary use (i.e. an EV, not a flashlight).
- Damage to a device induced by external means rendering it permanently inoperable. A lighting strike can induce an EMP damaging electronics. (This happened to me where I lost a couple dozen Ethernet ports across a variety of devices in my house).
Now, things that aren't permanently damaged, or may require some specific restoration sequence, are typically not considered bricked. Such as:
- Needing to do a factory reset on a device because you entered some parameters incorrectly.
- A corrupted boot volume that can be corrected with a wipe/reload
- A frozen host/process/GUI/etc... that needs a reboot.
- A battery that's too low to power a device up, but that can be recharged.
So, while it may seem like folks are splitting hairs here, the truth is that until you know what the state of your car is, calling it bricked is a bit premature. And given the history with folsk jumping on that term with the Roadster, and the degree of anticipation regarding the Model 3, I think many, myself included, are hoping not to give the clown brigade any more fodder than necessary for their FUD campaign.
Unfortunately, as seen above, it may be too late for that.
