Error removing DRM from Kindle books

[gianfri54]

Hello,

I am trying to remove DRM from some Kindle books using a PC with Windows 10. I have installed the DRM plugins and entered the serial number of my kindle. I have downloaded the book from Amazon using the Transfer to USB option, then imported them to Calibre. When I try to convert the books I get the error that the book is DRM protected and cannot be converted. Below is the log. I hope someone can help me. Thank you!!!

Is it an E-ink Kindle, not a Fire? If so, are you sure you chose the correct device when you downloaded the book? And double-check that you've entered the serial number correctly into the E-ink Kindle books section of the DeDRM plugin customization. Easiest way to make sure is to copy and paste from the website removing any spaces.

[gianfri54]

Yes, this is for a Kindle Oasis, I also have a Kindle Paperwhite. I copied the SN for both devices from the Amazon web site and pasted them (after removing blank spaces) into the plugin. I then downloaded a book for each of the two devices and tried to remove DRM but neither worked. I was hoping the log would point to some possible ideas (I am not tech savvy enough to make sense of it).

[ElleKayEm]

The log tells me that DeDRM tried the keys it had and they didn't work for this book. It then looked for Kindle for PC keys which, of course, weren't right for this book either. Did you restart calibre between entering the serial numbers and adding the books?

[gianfri54]

Well, problem (partially) solved. One of the two SN I entered had a mistake. After correcting it, books downloaded for that Kindle (Paperwhite) are converted by Caliber. However, books downloaded for the other Kindle (Oasis) are not, even though the SN in the plugin is correct. Thank you for your help!

[ElleKayEm]

Can you sideload the book downloaded for the Oasis to the Oasis and read it?

[gianfri54]

I deleted and re-entered the SN for the Oasis and that fixed the problem.

Thank you very much for your help and support!
