Still no luck with the Kobo. The error that I referred to was once the download took place it said that the Kobo was disconnected and to telephone (big red circle warning from memory).
When I did speak to customer support they recommended that I leave it for 4 hours or so and then try again as the server might be busy.
When I went to try again then the Kobo was no longer in upgrade mode and I couldn't get it back to that. I did plug it in to charge as I thought it might then be a battery issue with it having been in that state for 4 hours.
Following that I couldn't get it back into upgrade mode.
Subsequently, I did get it back into upgrade mode by performing CTRL + CENTRE DPAD + PLUG IT IN. That did work but when I did the forced upgrade again it went to the reboot screen but did not progress (I left it plugged into the computer).
I then rang customer support again while it was in that state and they suggested that it could be a low battery problem and to leave it for a whole hour. I was then to unplug the Kobo and reset it with a paperclip.
I followed these instructions but I only got the Read anytime, anywhere screen with the 7 dashes at the bottom.
I rang customer support again who suggested that I uninstall the desktop application, reboot the computer, redownload and install the desktop application and try again.
I did all that, but when it came time to put the Kobo back into upgrade mode again it wouldn't do this. I tried MENU + CENTRE DPAD + POWER, also MENU + CENTRE DPAD + RESET and also MENU + CENTRE DPAD + PLUG IT IN, but none of them worked. (When I do the MENU + CENTRE DPAD + RESET the blue light flashes and it just goes back to the anywhere anytime 7 dashes screen).
Is there anything further you can suggest to raise Lazarus from the dead? I so love the Kobo and want to get it working again with the new software.
On a positive note, I am now so dexterous I could join the circus!
