The kindle cloud reader has removed the cloud and download tabs. But when you open the book, a downloading progress will show at the bottom-right corner. Please just keep this book open until it has downloaded successfully. Then run Epubor kcr Converter to remove DRM and convert kindle books to drm free files.

While the automatic download with the new Kindle Cloud Reader worked yesterday as described, it does not today. Whatever I do and even with a long waiting time, the download does not start.
No message shown, just not starting the download. I'm using Macbook Catalina 10.15.6 with Chrome 84.0.4147.105 and Cloud Reader PlugIn.

reply
12/14/2020 08:58:22
No matter which way you are using, this is the right steps. Yes, the trial version only converts 20% content of each book. To obtain the whole content, please use the licensed version.
If you prefer something free, please try Calibre.

I've come across 2-3 books that need the latest version of Kindle to be read. If I keep Epubor running in the background then those books don't get downloaded. If I close Epubor, only then Books get downloaded, but then Epubor isn't able to remove DRM and asks me to delete the ebooks and re-download the book, while keeping epubor running in the background.

But running the Epubor in the background doesn't let me download the books... Are you getting me ?

reply
09/22/2021 09:41:00

Thank you for contacting us. Yes, I got you. That's because your kindle books can only be downloaded via the latest kindle app. And this is decided by the Publisher and cannot be changed. We are sincerely sorry to inform you that this kind of ebooks can not be decrypted because they are encrypted with tougher kindle drm.

We are sincerely sorry for the inconvenience caused.

02/27/2022 14:57:45
It can't work if your ebook has no "via USB" option.
reply
02/28/2022 10:05:50

To use download and transfer via usb method, you at least should have one kindle eink device registered with your account information.

If you cannot find via usb option, that's because you have no kindle eink device registered.

It seems the amazon kindle has changed something in the new published kindle books. It requires the latest kindle app to download it.

Now we are working on this issue. Once there is a solution, we will let you know. The older kindle books still can be cracked with Epubor Software.

There is still another way to remove drm from this kind of kindle books if you have any kindle eink device registered with your amazon account.

Tried method 3 - download and xfer via USB and it's not working.  I have an old Fire tablet which I am using and which is registered to my Amazon account

Here is what I did.
1 Went to content and devices and selected the download & transfer via USB
2. Plugged my fire into the computer I was using
3. Dragged and dropped the transferred file to EPU

Got the cant convert message

Then I tried:
1. Take the serial number of the FIre tablet and plugged it into EPUB
2. Dragged and dropped the transferred file onto EPUB

Got the cant convert message

Am I missing something or their other options

Kindle fire is not the kindle eink device. You need kindle paparwhite or kindle oasis or any older kindle eink devices, even the old kindle keyboard is ok.

I have the same problem. I can still open all the old books. Only the new ones I bought in 2023 no longer work.

That also does not work:
"There is still another way to remove drm from this kind of kindle books if you have any kindle eink device registered with your amazon account."

Can you please fix the problem, thanks

Also, as of a couple of days ago, content and devices no longer shows transfer via USB.  Your program and guides are not up to date with Amazon practices, as it won't convert these new books from 2023.  Calibre dedrm mentioned in your article won't convert or clean these new files either

Which method are we talking about here? How did you download your kindle books?
reply
02/11/2023 04:13:16
PC Kindle App Version 1.33.0 (62002) no longer allows for downloading of newly added content to the Kindle Unlimited platform. When I click the "Read for Free" button in Amazon, it gets added, but when I go into the PC Kindle App to download, an "Item not available for this device type" pop-up appears and says, "Your Kindle app requires an update to view this content. Click here to download and install the free update (supported OS: Windows 10, Windows 8)."  I am not sure where to go from here because I feel as though the your documentation doesn't help with this. Is there a workaround/fix for this?

"Download and Transfer by USB" works if you download the title and then drag that file into Epubor Ultimate. Don't try and access the file in "My Kindle Books." Worked for three titles  that I needed to add to my Calibre Library.

This is so frustrating and unfair to those of us who purchased a lifetime license and who were satisfied customers up until the converter no longer works for books after 2023.

As a longtime customer for several of your products I’ll be considering purchasing one of your competitor’s software if at least a refund isn’t offered soon.

I'm looking at the reply from: mikebrown that reads:  "Download and Transfer by USB" works if you download the title and then drag that file into Epubor Ultimate. Don't try and access the file in "My Kindle Books." Worked for three titles  that I needed to add to my Calibre Library.

That seems helpful but you would think someone from ePubor would publish a tutorial on how this is done. This tells you WHAT to do but doesn't show HOW to do it. You've got people (myself included) frustrated by not being able to get these newer ebook formats converted and it seems like you're recommending a method that no longer works.

Can someone from ePUBOR Ultimate show a step-by-step tutorial on how to do what mikebrown shares on this thread? You've got long-time customers who can't get this to work. Such negative feedback with likely deteriorate user confidence and reviews for a program that has always worked so well. I loved ePUBOR Ultimate until this happened.

I have Epubor Ultimate and as you are aware have the problem with removing DRM from Kindle KDX downloads.  I have been very happy with your software but now that it no longer works as it once did I am looking for a work around.
I believe that I read that the KDX DRM could be bypassed by downloading to a registered Kindle Paperwhite and then transferred(?) Is this a viable option now? I do not care to buy a Kindle device however if it will allow me to bypass the KDX DRM I would be willing to do so. I especially do not want to buy one if it will not work.
Also If it does work, what is the oldest generation Kindle that has the capability?
Thank you

NOPE.  I have tried all 4 methods you suggested and none have worked.  Why don't you just say you can't do it, instead of making us waste more money on the Kindle converter software that still doesn't work?

I followed your instructions to the letter and the kindle books I downloaded to the android APK app wouldn't even show up on the left side.  I followed all instructions on what to do when the books won't load.  Still won't.

Just stop wasting our time, and tell us to just download via USB in AZW3 format, and get a reader for AZW3 format to read the books on.  Just tell us you can't deliver the product you charged us for.

Hello, thanks for your comment.

Do you update your Epubor Ultimate to the latest version?

The lates V3.0.15.192 Epubor Ultimate allows you to decrypt and convert your new Kindle books downloaded by the latest V2.0 Kindle for PC. Please download the latest version of Epubor Ultimate and try again, thank you!

If there is still the same problem, please feel free to contact us via support@epubor.com.

reply
10/2/2023 04:19:44

I have even worse news.  So the AZW3 files you download via USB transfer, you can't even read with an AZW3 reader anymore.  This is a new update.  DRM won't let you read it, unless it's on a Kindle e-reader, cloud reader, or kindle app.  

Even with the latest update, Epubor cannot convert books using the latest version of Kindle.  

The only thing Epubor is good for now, is to use the old version of Kindle for PC and convert books published before 2023.  And if that book is a Kindle Unlimited book, you have to buy it.

Just tell us the truth, your software is useless now.  Stop having us jump through hoops and spend more money only to be back on square one.

I don't understand the good reviews here.
Epubor's conversion has failed on every single .kfx file, always with the same error message:
delete file, redownload, and start Epubor conversion.
I have firmware 5.16.2.1.1 on my Kindle Paperwhite.

What is also fake, is that the rating is automatically 5 stars. We cannot change it.

I tested Method 1 on the comic books I bought from Amazon Japan, and alas, this worked like a charm! I even tried it to decrypt the books published in 2024 (which my DeDRM plugin for Calibre could not handle), and it worked perfectly.

Just to make sure, I can't say for other file formats and/or methods that some users are not happy about. I only tested it on AZW files I downloaded via the latest Amazon Kindle software for Windows.

reply
03/18/2024 01:35:14
Just write KCR part at the top because all the kindle book is now KCR.
I spent 2 hours to find the solution.
