Same book, same settings & plugin, different download date, different result. [.azw file]

ahanqin commented 5 years ago

It seems that amazon has re-encrypted the .azw file on the server side.

For some reason, I have always converted the genuine e-books I purchased into epub format. Yesterday, I found that a few books I just purchased failed to convert. So I followed some friends' suggestions, uninstalled the latest 1.25 client, and installed the early 1.21 client. But it did not working. And I downloaded the same books that I had converted before, and the problem remains.

The following is a comparison of log files for reference.

Looks like it's not picking up the new key from version 1.21. And do you have it modified not to download KFX files? (Method 2 in this post.)

First, I'd try going into the Kindle for PC/Mac section of the plugin customization and deleting or renaming default_key. Then press the green plus sign. If that doesn't work, try completely uninstalling and reinstalling Kindle for Mac 1.21 following the instructions here:

Thanks a lot for your advice.

First, I had change the KFX method, with terminal command 'chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test' , and it does not work.

Then, I deregistered account, uninstall the app, remove all directories & files, reinstall and re-register the app, the green '+' button notified me: 'The default encryption key for Kindle for Mac/PC could not be found.' after a while.

In another case, the .azw file downloaded on 2019.01.25 cannot be converted again, because of all the k4i files were removed.

You are trying with a fresh download of the book from the current installation of Kindle for Mac? And Kindle for Mac is on the same machine and user as calibre with DeDRM?

Of course, more than once, whether it is version 1.21 or version 1.23, no matter how many books are downloaded, the green plus does not work at all.

I have already reiterated in the title, the same computer, the same user, I just converted a few books less than a month ago.

I have given up on this attempt, which wastes too much time. It is easier to copy it from kinlde and convert it.

Thank you again for your enthusiasm.

Yeah, I'm stumped why it's not working for you. Is it one particular book or all the ones downloaded with Kindle for Mac?
