Exporting modified epub don't appeared all corrected in Kobo Glo

[jiembe]

Until some days I was overwriting kepub books into my Kobo Glo with a new updated version. It was needed to reboot the device to get the new version running without flaw. But now what I get is the previous version of the Table of Contents which is erroneous; sometime viewing the cover get an error, etc. But the change character fonts appeared ok ditto for the changing class, etc.

I don't understand.

The problem is that when the Kobo device first sees a book, it extracts the metadata and ToC from the book and loads it into the internal database. This is then used in the library and when reading the book.

If the book is replaced, the default behaviour of the device is to completely remove the details of the book from the database and import the book as a new book. This would get the new ToC. But, lose the reading status.

Because of this, the default behaviour of the KoboTouch driver when sending a replacement of a book to the device is to make changes in the database to make it look like the book hasn't changed. This works fine if the only changes are things like spelling and styles, but it doesn't work if the structure of the book or the ToC is change.

You can turn this behaviour off in the KoboTouch driver. I added an option for this to the driver earlier in the year. Just turn it off to revert to the Kobo default behaviour.

Alternatively, delete the book from the device before sending the replacement. It doesn't matter whether you use the device or calibre to do the delete.

I try this but I don't get the previous behaviour. What I get now is a wipe out of the old kepub book version (annotation, serial anything gone as a completely new book) instead of forcing kobo to only update it's internal database.

That is the expected behaviour when you turn that option off. If the device sees that the book has changed, it removes everything and adds it as a new book. That is why the other behaviour has been in the driver all this time. But, with this turned on, it doesn't rebuild the internal ToC. You need to remove the book for this to happen.
