I don't know what the problem could be, but maybe some more information will help work out what is wrong:

Is the time/date set correctly on the device?

After the factory reset, the device should have updated to the current firmware version automatically as part of the setup process. What did you do to get back to firmware version 4.4.9439?

After you loaded the books and ejected the device, did it display a black "Processing" screen (on recent firmware versions the screen says "Importing Content")

If you connect the device to the computer again, are the books still there according to Windows explorer?

Edit: Did you set up the device via wi-fi or by connecting to a computer and using the Kobo desktop application? (setting up via wi-fi is best, it avoids some potential complications.)


I'll add that the most common reason for books not showing up is that they were put in the .kobo directory or some other directory beginning with a dot. They should be put in the root directory, or in a top-level directory you create yourself. This doesn't seem to be your problem, but I note it here in case others with the problem read this thread later.
