One more interesting note: The bibles can be downloaded directly, without dumping the content of the smartphone. It works like this:
- Go to bible.com and open a bible of your choice. The link in your browser's toolbar will be something like https://www.bible.com/de/bible/157/deu.32 (This is Schlachter 2000 in German)
- The number after */bible/ is the key, copy it
- Paste it into the following link, between */offline/ and -1.zip, e.g. http://d1ibykdbqak8v3.cloudfront.net...line/157-1.zip
- Download this zip file and unpack. The result is a folder containing 1 folder per book (e.g. Genesis, Deuteronomy, etc) with the *.yves files in them.
Using this, it should be possible to create a sophisticated Calibre addon that shows a list of bibles, and upon selection downloads imports and converts the chosen bible to epub.
