Night-Light21 commented 9 months ago

I also tried removing the converter plugin based on the ticket https://github.com/noDRM/DeDRM_tools/discussions/451. Calibre did not allow me to convert due to the file remaining as a KFX.

ElleKayEm commented 9 months ago

You need DeDRM 10.0.9 and the KFX Input plugin.

https://github.com/noDRM/DeDRM_tools/releases/tag/v10.0.9

RationalHuman commented 9 months ago

ElleKayEm-

Apologies if this not the appropriate place or method for posting a response - I literally just joined GitHub after reading the various forums, FAQs and posts in an attempt to de-bug an issue that suddenly cropped up two days ago in my use of Calibre and the de-DRM (now NoDRM) plugin. I've been using both successfully for years by downloading books from my amazon account for my linked Kindle Paperwhite, then storing the files in Calibre where I also removed the DRM so that I could read library books when I got around to it, rather than in the 2-3 weeks allowed by DRM. This was still working as of 2/5/24, but when I downloaded some library books on 2/20/24 I got an error message that they were locked by DRM and could not be opened. So I upgraded Calibre to 7.5.1 and installed both the NoDRM (first 10.0.3 then 10.0.9) and then, when it still didn't work, also added the KFX input plugin (2.8.1) and re-installed NoDRM 10.0.9, but still no joy. Any advice as to next steps?

Best, RH

ElleKayEm commented 9 months ago

You're downloading them directly to your Paperwhite? Are you leaving the files in their original folder structure?

RationalHuman commented 9 months ago

No, I download them to my PC (Windows 11), then load them into Calibre, then load them to the Kindle from Calibre. I assume Calibre is putting them in the appropriate folder on the kindle as they show up there and are readable on the kindle (at least for now)

ElleKayEm commented 9 months ago

Downloading them from the website with the "transfer via usb" option? Then you don't have to worry about folder structure because there's only the one file. Just make sure you pick your Paperwhite as the device and make sure its serial number is correctly entered into DeDRM's customization.

RationalHuman commented 9 months ago

Have done both of those (serial number, device) and it's still not working, despite having worked hundreds of times in the past with no change on my end - that's why I'm posting here

ElleKayEm commented 9 months ago

The log shows DeDRM doesn't like the keys you have in there for that copy of the book. Humor me and try this even if you're 100% sure it won't help:

Download a fresh copy of a book making sure you're choosing your Paperwhite (if you have more than one device). Copy and paste the Paperwhite's serial number from the website into DeDRM's customization. Click save or ok as needed on the way out of the dialog boxes. Restart calibre. Add the fresh copy of the book to calibre. If it still doesn't work, then I'd guess that Amazon has changed something about the way library books are encrypted. Or are you having the same issue with purchased books?

RationalHuman commented 9 months ago

So I deleted my old kindle serial # (which I had left in Calibre) and re-added the current one, as you directed, but got the same result. My wife, who has an older version of Calibre and DeDRM and her own kindle and Amazon account experienced the exact same thing when I asked her to try downloading and loading a library book, so I’m afraid it does seem likely that Amazon has changed how they handle library books. I haven’t tried a purchased book, as all the one I already own are already in Calibre with their DRM removed, but I suppose I could try deleting and re-adding one if you think it wb helpful

Thanks for all your help with this, BTW

Alright, I just tried myself. No issues. Try my instructions exactly as written.

RationalHuman commented 9 months ago

I must admit I was a bit annoyed by this advice, but I did repeat the steps, exactly and in order, and found that the old serial number I thought I had deleted was still there – I missed the ‘Apply’ button in the sequence. Repeated it all correctly, confirmed that the only serial number shown was the correct one, quite and re-started and re-loaded and…. It worked!

Thanks, again, for your help!

No need to delete serial numbers. As long as one of them is the correct one for that copy of the book, all should be good.
