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 ?
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.
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.
Method 3. Download &Transfer Kindle Books via USB

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
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
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.
Hello, thanks for your feedback.
We'll update our tutorial and add the steps you mentioned. Thank you so much!
best regards,

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
