Count me in on the morons side. I had to wait 30 minutes (
) for my Mini to factory restore, so I really thought it was bricked. In the end it did start anew on its own. BUT...
It is still giving me an "error communicating with device" in Calibre when connected, although no books are on it anymore. So obviously something went wrong in the fw, and no Peter, I did not load any "funny" file on it, I only loaded normal epubs. I always eject the Mini in Calibre, and verify that is indeed not found anymore on my explorer list before pulling the cord. I never updated it on my own but nicely waited for the on-air update, I did not change the internal sd card, and I did not drink the blood of my first born while attempting to cast a deadly spell on the kobo's dev, although believe me, I really feel like it right now.
I don't know what is to blame, and sincerely I don't care anymore, I just want it to work, and although your collective work for the connection between calibre and kobo devices has been indeed magnificent, it is a disgrace to imply that users that have problems with their devices have simply been looking for it to happen.
