Hi Booxtor,
Thanks for your suggestion. Unfortunately that didn't work out very well. After updating the firmware, the device no longer succesfully boots; it flashes half [only the right half of the screen] of a Boox startup-logo about a dozen times or so and then the whole screen flashes a few times in varying shades of grey, and at the end I am left with a completely white screen. The blue led is on.
I have tried inserting an sd card with older firmware (update-20120309.zip) that I read had previously resurrected another device (

Can you think of anything else I can do other than repackaging it and sending it back to the store?
