I purchased an ebook (two of them, actually) from some Japanese site called honto, but of course, stupid old me didn't realise that Digital Restrictions Management was going to make my life a living hell. Has anyone had any luck with cracking them, or did I just spend 730 Yen on a nothingburger?

Apparently, there are some local files on my phone from "doenloading" the ebook, but they won't load. In the browser I had a little more luck, but the images are scrambled when I attempt to "inspect element".

What do I do? I really want to get this to work...

What kind of file did it download?

[-] razrabotka@sh.itjust.works 4 points 1 year ago

There are a couple of files, actually.

This is the root directory.

Then, I go to the epub directory.

META-INF contains these files...

...and item has these files.

image and xhtml folders have the same amount of files (137), but the former has them in the jpg format, while the latter has them in the xhtml format.

Sorry for haphazardly explaining it like this, I'm on mobile.

I would try zipping up the epub dir and changing the extension to .epub

This should work, but this looks like an EPUB with DRM (since there's an encryption.xml file), so you might need to remove the DRM using something like Calibre.
