That's the newer KFX format which cannot be decrypted. See this post for disabling KFX downloads: https://www.mobileread.com/forums/showthread.php?t=283371

archz2 commented 1 year ago

Thanks , I used the KFX_begone4.bat mentioned in the post you shared (original link was this post https://www.mobileread.com/forums/showpost.php?p=4021279&postcount=966).

Then while trying to download the book, I got this error. error1

I am on Kindle 1.33 right now.

I am on Kindle app v. 1.33.62002 right now.

j-howell commented 1 year ago

There are some books that Amazon will only deliver to customers in KFX format using the latest DRM that has not yet been broken. These are mostly expensive textbooks and a few other categories that are more likely to be pirated. If your book is one of these then there is no DRM removal solution at this time.

If you share the ASIN (ten character identifier of the book on Amazon) it should be possible to determine if it is one of those.

archz2 commented 1 year ago

There's no ASIN available for this book. https://www.amazon.in/Build-Dont-Talk-Things-Taught/dp/0143459686/ref=sr_1_2?crid=2YHESJSIKXATN&keywords=build+dont+talk+raj+shamani&qid=1670692606&sprefix=build+dont+%2Caps%2C453&sr=8-2

It's a very affordable book. It seems as if Amazon has beefed up its security for all the newly released books.

j-howell commented 1 year ago

The ASIN B0BLD6VK6B. Many book published in India use the stronger DRM that cannot be removed. This is one of them.

archz2 commented 1 year ago

Okay, is there any alpha-numeric pattern you see in the ASIN that gave you the clue of unbreakable DRM?

ElleKayEm commented 1 year ago

On the page for that specific ASIN, it says:

On Android and Fire tablets, the latest version of the Kindle app is required. This title is not available on Kindle Cloud Reader.

j-howell commented 1 year ago

The web page for that book on Amazon.com (https://www.amazon.com/Build-Dont-Talk-Things-Taught-ebook/dp/B0BLD6VK6B) is even more explicit. It adds:

On PC & Mac, the latest version of the Kindle app is required. On E-readers, this title is available on select devices, and latest software update is required.

These are indications that the book is only available on apps and devices with unbroken DRM. That is common for books published in India, expensive textbooks, and a few other categories where the publisher has opted for only the strongest DRM.

archz2 commented 1 year ago

Thanks a ton @ElleKayEm and @j-howell . Really appreciate this insight! I bought an Indian book today that got published this month which costs thrice as much. I was able to remove its DRM successfully, thanks to the info shared by you!

The DRM cannot be removed even if the book is downloaded on a Kindle paper e-reader device, then transferred via USB to Calibre on a PC for DRM removal?

ElleKayEm commented 1 year ago

No, that will still have the latest unbroken KFX DRM.

archz2 commented 1 year ago

How old is this latest KFX DRM system? I'm thinking that it's a cat and mouse play that happens between the updates of this plugin and Amazon Kindle amping up its DRM security.

ElleKayEm commented 1 year ago

Very much so. The last two updates to DeDRM which addressed this stopped working within a day. So Amazon is watching. They mearly flip a switch and all subsequent downloads are undecryptable by DeDRM but their own software can already handle the change.

archz2 commented 1 year ago

Okay.
