I wonder if I could lick a 9 volt battery and play back some high frequency tones through my headphones to get a similar effect?

May have similar results as overwriting your bootloader binary with the same number of bytes from /dev/random.

Just make sure your batteries are at least 80% charged or you are plugged in. Power loss during a firmware update like that can be catastrophic.

Probably not. It's become apparant that the timing component is critical. The electric pulses have to have certain timing characteristics.
