DRM workaround: Kindle for Android

[bizzybody]

I got the alpha release of DeDRM, updated Calibre and plugins. Installed the latest K4PC and re-downloaded my whole library.

Calibre didn't complain about any of them. Very nice. I can stop using the very slow old tablet to download books for backing up from then running through Calibre.

Did you have any extra steps you did to be able to read your books? I've installed DeDRM 10.0.9 and KFX Import and while Calibre can add the book to the library and pull its metadata, it can't open it or convert it to a PDF and the error calls out that it's because of the DRM on the file.

I've followed the steps that lkmiller and David outlined as close as I could, my only real concern on that front is that I for sure downloaded the 10.0.9 release candidate for DeDRM but Calibre lists the version number as 10.0.3 when I install it.

This method was what I came to after the one OP described with Bluestacks Nougat stalled because the backup step wasn't displaying a confirmation in the emulator--a few people ran into that and no one really provided a fix, I couldn't even find one elsewhere on the web.

10.0.3 won't remove the DRM. And the latest Kindle for PC (2.4.1) no longer works either - you need the version 2.4.0.

[lkmiller]

If it is still showing 10.0.3, then you reinstalled 10.0.3. Make sure you are navigating to the 10.0.9 folder when loading into calibre. Then restart calibre. And as Sirtel said, it will need to be no later then Kindle for PC 2.4.0.

The old Android app method may be done anyway. The last time I tried to download with 4.16.0.75, it said something about that version not being supported. It wasn't the ebook either because I was able to download it for an E-ink Kindle, and I got an AZW3 which decrypted without issue.

Thank you both; looks like I missed both that a new revision of K4P dropped since then, and the step to restart Calibre when removing 10.0.3 before adding 10.0.9 (I know it literally tells me to, I was rushing and frustrated...)

I've got everything working now, glad this is way easier now than all the other stuff that people had said to do before I found this last little set of developments!

Do not install 10.0.9. Install the latest version which is the auto-generated alpha release. at https://github.com/noDRM/DeDRM_tools...947bf338d3ffda

If your KindleforPC is 3.4.1, you'll need to roll back to 2.4.0 or you won't be able to remove DRM.

My Windows Kindle app (on Mac using parallels) just updated to 2.4.1 even though I had the install updates automatically turned off. What's going on and how do I stop it?

1. Install 2.4.0 over 2.4.1.
2. Go to this post and download the bat file for Windows https://www.mobileread.com/forums/sh...71#post4444671
3. Run the bat run for Windows

Done!

You could try installing 8.51.1.0 (1.3.272119.0) over 4.16.0.75. See the quote from @DuckieTigger in the first post in this thread for more information. The APK is still available from APKMirror

If you're on a Mac you can abandon Parallels and use Kindle for Mac 1.40.1. You can find it on third-party sites with Google.

I managed to create an Android backup of my tablet, but when I try to add the backup.ab file (size ~55MB) to the DeDRM tool, I get this error message:

Any ideas on this? BTW, apologies if this topic has been covered before. I tried the search function without success

@Memowho

You will need the alpha auto-release of DeDRM which has a fix for that.

To download your books, you also may need to follow DuckieTigger's instructions in the first post for updating to 8.51.1.0 of the Android app. The older version is needed to get the backup to extract the key, but it wouldn't download a book last time I tried.
