Hmm, the update is failing for me... I just made a factory reset before to avoid possible problems. Now, when the Kobo Desktop trys to update the firmware, the usb connection suddenly drops and Kobo Desktop is complaining about the device being full (device information shows 1309mb free space before and after, btw).
Does anyone have an idea, what to do about this? :/
I already tried a different usb port, but that didn't change anything.
