I then tried pushing all three buttons once for a few seconds to see if that would force it into 'download mode' and might do any good. At which stage it stopped responding completely. For those that are interested, this is what it now looks like:

(If you look carefully, you can see elements from multiple screens.)

I have put in an inquiry with Onyx, and may have to do a warranty return.
Freaky screen...
Yes, I had come as far as figuring out the command for the update via adb when realizing that you would have to turn on usb debugging before and getting there would require at least as many blind taps as trying the update directly...
So did you not tap the correct positions or did the update run but not fix the problem?

As far as button combinations on boot go, I've found:
Holding the "next" button while booting gets you into fastboot mode (screen showing "Boox reader"). Nice if you want to flash custom recoveries but I'm afraid we're not that far on the Kepler - if anybody feels adventurous enough to try one of the rooting methods for other Onyx devices, I'd be extremely interested, but I won't do it
Holding the "previous" button and letting go at the right moment gets the Kepler into a state where neither adb nor fastboot works, again showing "Boox reader"; otherwise the device just boots normally.
Holding both buttons on boot, the device doesn't even start up
