My wife's PRS-300 is not booting currently, and won't get past the "Opening book..." splash screen.

I left it charging overnight (on a charger, not usb), but I'm still seeing the same behavior.

If I soft reset it with the reset pin, and power it back on:
The screen wipes and refreshes
The power light comes on solid, then starts flashing
Screen sticks at "Opening book..."

Up until a minute ago, hard resetting had the same result: just got stuck on "Opening book..." indefinitely, no prompts provided.

Now, suddenly, it's displaying "Firmware update did not complete successfully. Please try again" after a moment.

If connect it to my machine, it mounts a single, 44.0kB drive with containing a 0 byte "Protected !!" file.

Any suggestions?
