Is there a way to rebuild the cover cache?

Hi, I'm having some issues with my PW2. I've removed (but I still have the backup) some of the covers from the thumbnails folder along with the linked books. Then through calibre I've added again the same books (this time with a different cover) but the cover won't show up in my kindle.

Is there a way to rebuilt the cover cache?
thanks.

@Belenos-
First, be sure to do a reconversion in Calibre after changing the cover of the book to make it 'stick'. After reloading the book, do a restart of your kindle. If that doesn't clear the cache, remove the book, do a restart of your kindle then re-add the book. Cheers!

If it is an official Amazon file, containing a mobi-asin and was never converted (it won't have the "personal" banner) the thumbnail MUST be sent to it! calibre will do this automatically.

I have noticed if this file is a .mobi, the Kindle won't recognize a change until you delete and re-add the book. I keep a rsync backup so it is easy to restore everything.

For anything that will have the personal banner, your Kindle will autogenerate a cover when it sees there isn't one already.

In my experience, this is only necessary for .mobi, with the proviso that restarts do nothing.

Although usually that is a great way to fix problems, not here.

Curious..I never had this issue with my K2, but have had it several times with my PW1...a persistant cover cache. The only way I was able to clear it so the new cover would show was by doing a restart. (Both with mobi and AZW3)

And mine is a Kindle Touch. It seems to cache the .mobi covers only. So who knows what the PW2 will do?

Whatever the PW2 does, I'm sure Amazon will call it a 'feature'!!

After changing the book cover, yes. (there are some newer features in Calibre like 'polish book' that allow you to change metadata without doing a reconversion, but I can't recall if book covers is included....I know that doing a reconversion mobi-to-mobi works)

"Polish" only works with ePub and AZW3, not Mobi.

Although metadata updating does work when sending/saving to disk. However, it cannot replace the cover image in a .mobi, only update the meta fields.

.azw3 supports polish AND update-on-send for everything.

When I was testing the thumbnails thingy, I found that removing a book *from the Kindle UI*, then triggering a catalog rescan (be it via a framework restart or a switch from USBMS to Framework) after re-adding the book usually did the job to get rid of the persnickety caching...

If the delete happens from an USBMS session, add another catalog scan. (delete, scan, re-add, scan).

EDIT: I'm clear as mud.

1/ Delete book from the Kindle UI.
2/ Switch to USBMS
3/ Add book
4/ Unplug

OR

1/ Switch to USBMS
2/ Delete
2/ Unplug
3/ Switch to USBMS
4/ Add book
5/ Unplug
