DxO One not focusing, keeps turning itself off... Anyone have the firmware .bin I could reinstall?

I have an iOS DxO One which has started to act up. When I press the shutter, the motor whirrs for 5 seconds, then the camera shuts down. Occasionally it will capture a photo, but will only focus within 1 meter of the lens. I would like to try reinstalling the latest firmware. Does anyone have it or know where I can find it? Alternatively, does anyone know how to dump it from another working camera?
Thanks for any help you can offer.
