I want to buy an ebook that's only available from Amazon, and I want to remove the DRM to side load it to my Kobo. I don't own a Kindle device. Back in 2020 I remember being able to do this by using the Windows Kindle app, Calibre, and Apprentice Harper's DeDRM tools. But that doesn't work any more. So I tried the following:
1. Downloaded the latest Kindle app (2.3.1 70682).
2. Downloaded the latest Calibre
3. Downloaded the latest DeDRM_Tools from
https://github.com/noDRM/DeDRM_tools/
And that didn't work either.
Is there a link documenting the steps I need to take? Do I need, perhaps, an older version of the Kindle app? I've kept version 1.26 but it didn't manage to login.
