Well I spoke too soon, now when I plug in my kobo I get this: failed to backup device database

calibre, version 7.12.0 (win32, embedded-python: True)

Ok, solved this by creating a new backup destination folder, the previous one was somehow non-existent.

Plugins sometimes need to keep up with major Calibre changes.

FWIW it works on W10 Calibre 7.12

Works on Windows 12 with calibre 7.12 as well.

I can't seem to run any firmware newer than 4.35.20400 on my Forma. I have 2.16.13 of the plugin installed into Calibre 7.12 running on Windows 11. This has actually been a problem for me for more than a year. Any time I try to update my Forma, within 1 or 2 sync's my database is corrupted and I start getting errors backing up the database and the device stops "remembering" where I was in a book I was reading. I immediately downgrade to 4.35.20400, restore a backup of the database, and life goes on just fine until I try and update again. Once I left the WiFi on and my Forma updated itself to a newer version with the same result.

This problem has persisted with me since Calibre 6 and my old Windows 10 system.

Is there some good way for me to try and diagnose this?

Newer versions of the firmware have issues with database corruption. The general consensus is the best way to prevent it is to reboot the device before connecting.

Ahhhhh, this makes total sense. I have NickelMenu installed now with a reboot menu option and I have upgrade to the latest firmware. So far, so good. Let's see what it's like in the long run.

Thank you for the information.
