What surprised me was the old Android app can download the books published in 2023, which only Windows app versions released in 2023 are allowed to download. Then I was able to copy the books to my desktop and put them in Calibre. So I had to remove the SD card and plug it into my desktop's reader. But the tablet was still hiding the contents of that folder from Windows. To get the books off the tablet I have to use a file manager on the tablet to copy them from internal storage to the SD card (I just copied the folder where Kindle saves the books). It's the last one that allows doing an ADB backup of the Kindle app and data.ĭownload a few books, pull the backup, then use that file in the DeDRM plugin in Calibre to get the Kindle key from the old app. Those previously DRM-free books now have the new DRM, even when downloaded with the older version of the Kindle app for Windows I'd been using to ensure I was getting a format Calibre could work with.Ī workaround I found is to use an old Android tablet with version 5.1 or newer and install the last revision of Kindle 4.1.6.
Since I have them converted and backed up elsewhere, I deleted a few from my kindle content folder and re-downloaded.
I've bought some books by authors whose books published in 2022 and before do not have DRM, but the latest by them from Amazon has DRM.
