How to Downgrade Kindle for PC/Mac Manually or Automatically 2021

Posted by on .

Why downgrade kindle for pc/mac to older version? As amazon has released its new Kindle for PC/MAC version 1.25, its DRM scheme is much tougher than ever before. Kindle books downloaded via Kindle for PC/MAC 1.25 (or higher version) will be encrypted with the new kindle kfx DRM, namely Kindle KFX 2. Currently there is not any software around the world can remove DRM from Kindle books downloaded via Kindle for PC/MAC 1.25 or even higher version. As every software is not perfect, we believe that we can find the direct way to crack kindle new kfx DRM sooner or later. For readers who are reading this article, we have provided the temporary solution to bypass the kindle kfx 2 which is downgrading kindle for PC/Mac to older version. With this workaround, you'll download old kindle kfx format ebooks and find many tools on the market to decrypt and convert kindle books.

I've downloaded the free version but I cannot read my Kindle ebook it appears a message that only 20% has been uploaded. So I don't want to buy this software if I am not sure that it will be ok. What can I do
Thanks in advance for your reply
reply

Thank you for leaving the message.  Since you are using the trial version, you will only get 20% content of the original book. It means our software can handle kindle books. You can just go to purchase it to get the whole content of your Kindle books.

When I used kindle (version 1.24), there is a message that " Your kindle app requires an update to view this content. Click here to download and install the free update (support OS: Windows 10, Windows 8, Windows 7)."
So, I couldn't download a book on kindle (version 1.24), and couldn't use Epubor Ultimate.
But I can download the book on the newest kindle version.

How should I deal with the problem?

As you know the older version of the Kindle app will not work on 10.15 or higher. Using the KCR works but some books are not available for the cloud reader. Will you be updating the program to work with the newer versions of the Kindle app?

I downgraded Kindle to 1.24 and downloaded Epubor Ultimate. But Epubor Ultimate asks for a licence email to register. When I try to do that with my registered account for Epubor KCR I get the message 'You are recovering the wrong product'. Epubor tells me also that I'm still using Kindle 1.29 but I checked and it's 1.24 for sure. Do I need to buy Ultimate now to convert my Kindle books? The instruction doesn't mention paying, it says download Epubor Ultimate for free.

Hi. My version of Kindle I downloaded is version 17.7. I downloaded the plug in and use it on the caliber I download. It says syntax invalid. Please advice me.
reply
11/4/2020 09:05:41
Thank you for your comments. That's because the latest calibre is written by pathon 3 but the dedrm plugin is written by pathon2. That's why there is syntax error.
Two solution: 1. use epubor ultimate 2 revert to calibre 4.0 and then install the dedrm plugin again.

This doesn't work. When you try to install the old 1.23 Kindle version on macOS Catalina, you get this error message:
"The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information."

There is no way to bypass this.

Please check your network settings and proxy configuration. Network settings can be found under Tools>Options>Network."  I tried changing the proxy from auto-detect to No proxy.  Either setting leads to the same error.  I am connected to the internet and am using the same computer to send this message.  I've also tried uninstalling, rebooting, and reinstalling 3 times now.  I would appreciate your help.  Without being able to login to my kindle app (on windows 10), I can access any of my books.

Hello,
Thank you for the advice on how to convert files from azw to epub.
It used to work for me and I have used Calibre and Epubor for a while now but all of a sudden it doesn't work anymore.
I have the right version for Kindle (1.24.3 (51068))on my computer (Windows 10) but I get a message saying that the book I want to be converted is protected by DRM.
I tried to do it directly from Calibre but no joy there either.
Any idea?
Thanks for your help.

I have used the free trial version. I tried to remove the DRM to a Kindle rented book and it says that "We don't support rented books". It means that I have to buy the book to be able to download it into my PC? How can I be sure that Epubor software can download the book once purchased on Amazon?

reply
11/13/2021 11:58:19
I installed and downgraded to the old Kindle version, My book indicates it converted, however I only see your info page that says the file is only 20% converted, when in fact it is 0% converted.  I want to be assured that the book (s) will actually have DRM removed and convert to pdf.
