$20 can't be that bad, right? and there's probably a serial port, and i can figure out the serial port and be the hero who figures out how this works.
Well, the spots on the board that looked like they might be surface mount pads for the serial ports that are there on later revisions? Those are just, pads. There's no serial port there. There's no voltage either. They may do something, but they don't appear to.
Eventually I got out a usb to ttl serial, taped the ground lead to a ground pad, and probed around the test points with the rx lead. I did find a test point that at 115200 is pulsing at a rate that looks like the number six over and over but it's probably just a clock, and just coincidence.
And then i turned it off by holding the slide switch until the screen went dark.
And then i held down the 'home' button and held the slide switch out.
And then it displayed the "restoring to factory defaults" screen.
And then it booted up and connected to usb on my laptop as a mass storage device.
It now appears to be a completely normal N905.
It's possible that my frustrated probing corrupted a flash image and triggered a reload. This is generally the most foolish way to restore firmware but people do it on routers and settop boxes and the like. It's a time-honored, really stupid way of reviving electronics.
Or maybe it turns out that these demo units will re-flash themselves if you hold down home and the slide switch while turning them on.

Sounds as if you triggered the factory restore process.
