If it is the result of the bad update, it's potentially still on, so you can either
a) fish around on the dark screen for the connect button (as some others on the Aura One thread did) after you plug it in to your computer
b) or power it off with a brief press and reboot into restore/factory reset, which is what I did.
The only thing I'm not sure of is whether the wifi update is still pushing the bad software for the Aura 2nd ed, which is why I rolled back. It was pushing the bad one on wifi update for quite awhile yesterday. Don't ask me how I know.
