One question : is version 3.48.0 of Calibre compatible with Aura H2O firmware 4.20.14622 ?
If not, what would be the most recent Aura H2O firmware I should install on the Kobo device (assuming I would be able to do downgrade the Kobo firmware).
Are you still getting the same error message? If you are, then no version of calibre or the firmware will help. That error means that there is a problem with the database. Signing out of your Kobo account on the device should fix it as the removes the database and creates a new one. Occasionally, you need to do a full factory reset to fix the problem. And if that doesn't fix the problem, it could be a hardware issued. The internal SD cards (for the devices that have them) can fail and need to be replaced.

If you are getting a different error, what you do depends on what the error is. If it is the one about the version of the firmware or database, then you can safely follow the instructions in the message. These are the normal instructions for newer firmware until there is a calibre update to match.

I assume that you are running calibre 3.48 because the version of MAC OS that you are running cannot run the newer versions. The version/name rings a bell for that. But, there are occasional problems with MACs where they start mounting these devices as read-only. I don't think the error above would come from that, but, it is something to check.
