The absolutely "leetest" thing I have ever seen was a device where the firmware update was to be done by: 1. Hold a button while booting (pretty normal) 2. This reconfigures the circuit path of one of the LEDs so it is reverse-biased to VCC via its resistor and switches one of the microcontroller GPIOs to ADC input 3. You go to a website that plays a strobe pattern (encoding the firmware) 4. You hold that website in…

Another example of firmware update reusing something that is already there: some electric guitar effects from TC Electronics can be reprogrammed by bringing a phone close to the guitar pickups. The phone app encodes the data as sound that is picked up by the guitar pickups and sent down the chain to the effect.

Ahh good example I remember having done that myself before!

Sure it's clever. But it also means you can't repair the appliance without the manufacturer's server to decode it for you.

Owner of an LG washer that failed here. All the same diagnostics you can do at the machine, the phone home service allowed a remote engineer to diagnose as well. Things like drum rpm, tilt/knock sensors, uneven balance detection. Instead of paying a human $250 to come out and press buttons, they can do it remotely. I understand in the pessimistic age of John Deere, all remote diagnostics are bad, but that is not the…

How were you able to diagnose it yourself? Just through the error codes, or is there another interface available for non-technicians?

You enter diagnostic mode on the panel, there exists a service manual which describes the process
