My Kobo Aura HD started locking up and being glitchy after installing the new firmware a few days ago (thinking maybe the installation went wrong) and after a few attempts at fixing it I decided to do a factory reset. It worked!
However, I notice that even though the device has the same serial number, Calibre seems to consider it a new device. I had to re-add it to Reading List and Kobo Utilities. Why does this happen?
