2. The v10.0.0 versions of this plugin should both piece of work with Calibre 5.x (Python 3) besides as Calibre 4.x and lower (Python 2).
3. Users with calibre 5.x or later can use the latest version of plugins at present. Users with calibe iv.x or earlier should apply release 6.8.x of the tools.

Office iii. DRM removal plugin failed to install Bug
Have followed the to a higher place steps but the calibre dedrm plugin is non working?
SyntaxeError: invalid syntax

As of calibre 5, calibre has moved from Python ii to Python 3, because Python 2 has been end-of-lifed.
To resolve this bug, you lot simply need to update your Calibre to the latest version, and and then add the DeDRM plugin v7.1.0 to calibre. If you've added the older version of drm plugins, delete it from calibre start and and so re-import.
Unhandled exception: does not contain a summit-level init.py file
calibre, version iv.23.0 ERROR: Unhandled exception: InvalidPlugin:The plugin in u'/Users/bradcrandell/Downloads/DeDRM_tools_6.8.0.zip' is invalid.

It does not contain a top-level init.py file 
You see this error may be because y'all added the whole archive file into calibre. Unzip the DeDRM_tools_6.8.1 archive, and look in the DeDRM_tools_6.eight.one folder for the zero file(named DeDRM_Plugin.zip and Obok_plugin.zip) to load into calibre.
Another reason is the downloaded drm plugin file is not the latest version. If then, you lot should remove the older version plugin first, and then download the latest one and import them again to calibre.
Function four. How to unlock DRM from Kindle KFX eBooks with Calibre plugin?
Since Amazon started using new KFX format to Kindle eBooks, calibre plugin no longer works for unlocking DRM from KFX format. The DeDRM plugin here works with not-KFX Amazon books only, and the solutions introduced here are walkaround solutions, not the direct (quick) one.
Note that Amazon changes the DRM for KFX files often. What works for KFX today might not piece of work tomorrow.
1. The plugin doesn't work on books downloaded from Kindle Burn(HD) tablets, Kindle for Android/IOS applications.
2. The tools do not work with the Windows 8 AppStore Kindle app.
3. To convert KFX to ePub/PDF with Calibre, the KFX Input Plugin (version 1.36.0 at the time of writing) must be installed likewise.
iv. If yous take a Kindle e-ink device, don't directly download and import books to calibre as information technology doesn't work on these files. Simply you tin can download and transfer via USB to your device, then the downloaded file will be .azw3 format. Import azw3 to Calibre and configure the DeDRM plugin by inputting KSN, then you can besides remove drm.
Walkaround 1. (For Windows) Install an outdated Kindle (such as version one.17)
If you have downloaded the latest Kindle for PC, deregister the Kindle PC app outset, and and so uninstall it from your windows computer.
Install, launch, and annals this Kindle installation with your own amazon account.
Don't forget to uncheck the auto-update from Kindle's settings. Otherwise, when you launch it next time, it will update to the latest version automatically, which does non work with DeDRM.
If asked if you desire to update to the newest version, ever select "Skip this version" delight.
Now you can select books from your Kindle library and download them to your local Windows.
Important:
Yous tin can find(and even alter) the kindle for pc books location by clicking on "Tools" > "Options" > "Content" > "Change Binder".
Import Kindle books to Calibre library, and the DRM will exist removed.
As the above image shows, the drm removed KFX books will exist turned to KFX(non-DRM). Afterwards you installed the kfx input plugin to calibre, you can continue to convert kfx eBooks to other formats.
Walkaround two. (For Mac) Avoid KFX downloads by renaming renderer-test on Kindle for Mac
Important:
For mac calculator users, we tin likewise use an older version kindle for mac（such as v1.17) to get around the new kfx format. Just in fact, considering that the older version kindle app can't run on catalina and big sur, while more users have updated (or will update presently) their mac system to the newest one, so here I write down this solution in detail for Mac users, salve your time to understand and test.
The central to avoiding KFX downloading from K4Mac 1.25+ is to block KFX with chmod -x, then download books using correct-click on mouse and selecting "Download".
Install the latest version of Kindle for Mac or update to the latest one, v1.30.
If there are kindle books already in the "Downloaded" tab, remove them offset(Remove from device).
Then, run Terminal app, copy and paste following command in terminal, if needed input countersign to execute command.
sudo chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test 
If you don't accept a password, and so run this command.
chmod -10 /Applications/Kindle.app/Contents/MacOS/renderer-exam After patching the Kindle app, run the Kindle app and select ane book, right-click and "Download".
The downloaded books are saved under "My Kindle Content" folder. By clicking Kindle > Preferences > Content > Modify Binder, you can observe and modify the location.
At present you tin can import the downloaded kindle books from "My Kindle Content" folder to Calibre, then as what yous see, the drm is removed automatically and calibre turns these books to AZW3 format.
Note:
Right-click to download is key important. If you double click to download the book, you will get the new kfx or kcr format.
After the downloading is completed, DON'T double click to open it, otherwise it will cause the Kindle app crashes unexpectedly. The downloaded onetime format is incompatible with the newest kindle app. After all, amazon prefers us to download and utilize the new KFX format.
Kindle KFX DeDRM Failed and Solutions
01. The Kindle DRM has been removed, but all the pictures are gone
Nigh likely, this is an AZW6 format book that the tools don't back up. But as the azw6 is only downloaded direct via Kindle e-Ink device, so the solution is downloading your book by "Download & Transfer via USB".
02. The Kindle volume (AZW4) conversions takes a long time
The AZW4 is a Impress Replica Kindle ebook. This is a PDF in a Kindle wrapper. After you adding it to Calibre, the azw4 DRM will be removed successfully. Now all you lot should practice is using the KindleUnpack plugin.
03. AZW/KCR/KFX-ZIP in Calibre
In fact, if Calibre shows the volume in "AZW", "KCR", "KFX-Nada" format after you add together one book to the calibre library, information technology's probable that Calibre failed to remove its DRM.
Run across, after I click on "Convert books" and select "epub" to convert, calibre shows the in a higher place fault message.
To avoid this, I would say delight follow all the details step by step equally what I write at the in a higher place.
Y'all can also click on the "Jobs: 0" label in the lower correct corner of the calibre window to activate the Jobs dialog.
Select the failed conversion job from the list (the most recent will be first) and click the "Testify job details" push. Copy the log to the clipboard then paste information technology to Github or Mobileread for help.

Role 5. How to disable DRM from Adobe Digital Editions (ACSM)?
The installed DeDRM plugin besides works on Adobe ACSM files, such as the downloaded books from Google Play.
You lot will find that the downloaded file is in acsm format. ACSM is associated with Adobe Digital Editions. Information technology means we must apply the ADE to open this type of files.
The first time running ADE, you lot should qualify an Adobe ID, and so open your acsm with information technology. When the acsm is opened via ADE, the acsm is turned to ePub or PDF (depends on ebooks vendors), only with DRM. And they are stored nether "My Digital Editions" folder.
At present you can import them from the digital editions folder to Calibre. Then, the Adobe DRM is removed by the dedrm plugin in Calibre.
Annotation:
Non all the acsm files that y'all downloaded from an online eBook store volition be supported by the dedrm plugin, though you tin open them via ADE.
You may meet problems when authorizing an Adobe ID or opening acsm file via ADE.
Delight ensure that you are using the same electronic mail address as your ebookstore account'south, this is important. Another reason is you used an incorrect Adobe ID, if so you should switch your adobe account to login.

Part 6. How to Apply Calibre kepub plugin?
The Obok_plugin.nix you added to Calibre is used for removing DRM from Kobobooks. By default, Calibre will show this plugin at the top carte bar.
Firstly, you should apply Kobo for PC/Mac to help download your books.
Where to discover them? Books downloaded via Kobo PC are saved here:
…\AppData\Local\Kobo\Kobo Desktop Edition\kepub And Kobo for Mac books are saved in this location:
.../Library/Application Support/Kobo/Kobo Desktop Edition/kepub Launch Calibre and click on the "Obok" plugin. If you lot don't see it, click on the three dots icon at the top menu bar.
Then from the popup window you will find that it automatically detects all of your downloaded Kobo EPUB books.
The red lock icon ways that book is drm protected, and the dark-green lock icon means that book is drm gratuitous. To crack those drm protected books, you tin click "All with DRM" and and then touch "OK". Await for the job to consummate.
Now the drm limitation is removed from your Kobo books, and they are in EPUB format (the original is kepub, with drm). If you lot want to transfer Kobo books to Kindle, you lot can continue to convert them to Mobi format in Calibre.
Tips that work:
1. If you already downloaded Kobo books on Kobo eReader, you can also connect information technology to the figurer and so import that book to calibre and so that you tin remove DRM directly from them.
2. If you employ the Kobo desktop app to help download files, download and install the app from Kobo official site please. DON'T install the app from any app stores. Otherwise, you may neglect to remove DRM from kepub.
iii. Couldn't find the kepub binder on Mac? Use Terminal and running following command: write com.apple.finder AppleShowAllFiles yep
then Enter.
