David kindly sent me a link to get the N647 firmware and instructions to load a new image to the internal microSD card. The reimaging went well, I did it on a 2Gb card and a new 8Gbcard, I could see the partitions created OK using MiniTools Partition Wizard.
But putting either of the cards into the Kobo WiFi doesn't seem to work. But maybe this is not a firmware issue. The display is frozen - showing kobo logo, eReading: anytime, anyplace and 5 blocks in the bottom right hand corner. The display doesn't change no matter what I do (even unplugging the battery).
I don't seem to be able to power cycle the Kobo - I have tried the long press on the power button until led goes off (display stays the same), press to power it on. I have tried the reset button (several times with light on and off) - nothing changes. If I plug the USB cable in the light changes to a purple colour, then straight red if I hold the power button for a long time.
At the moment I am trying to flatten the battery by leaving it on (blue light showing) but that could take a while.
Any suggestions from anyone as to what else I can try? Starting to think it is time to replace it with something else.
