If you are getting another error message, can you please take a copy and post it. Maybe PM it to me so I can tell.
The exact error message is:
Kobo database version unsupported:
Your Kobo is running an updated firmware/database version. As calibre does not know about this updated firmware, database editing is disabled, to prevent corruption. You can still send books to your Kobo with calibre, but deleting books and managing collections is disabled. If you are willing to experiment and know how to reset your Kobo to Factory defaults, you can override this check by right clicking the device icon in calibre and selecting "Configure this device" and then the "Attempt to support newer firmware" option. Doing so may require you to perform a factory reset of your Kobo.
Your suggestion seem to bypass this issue.
Though I wait for an update for calibre.
Looks like the metadata isn't working correctly.
I updated a book coverpage in cailbre, but this change is not reflected on the device.
