As we all know, the accounts of Central Asia and America Asia are not interoperable. That is to say, if we buy a genuine Kindle book from Amazon China and Amazon America at the same time, we cannot read it on the same Kindle device (Kindle mobile app as well).

There are two ways to solve this problem.

One is the way we can switch the account to achieve the purpose of sharing books, but there are a lot of problems with this approach, the kindle mobile applications can’t directly choose login area, must by switching system language to the corresponding central Asia or login account, the united when switching accounts at the same time, the previous account books will be erase. While switching accounts on the Kindle saves books from the previous account, switching accounts frequently with the Kindle’s response speed can be costly and time-consuming.

The second method is to download or export purchased Kindle books and then send them to a designated account by email. This method is relatively convenient. We can download purchased e-books directly from Amazon, or export them directly from the device. However, it’s not that simple. All e-books on the Kindle are drM-protected and cannot be opened when transferred directly to the Kindle.

At this point, we are required to crack the DRM, which is the subject of this article.

This method is only used for legitimate books purchased by yourself and for personal reading only. Do not use it for pirated e-books.

Get e-books

First of all, we get the e-books in AZW or AZW3 format that we need to crack. There are three ways in total.

Download it from Amazon

Go to Amazon and select Manage My Content and Devices from my Account in the upper right corner.

Then, select the book you want to download and click “… “in” Operation “. Button and select Download USB transfer from computer.

Then, in the pop-up window, select and click “Download”, you can save the ebook to the local.

Download using Kindle desktop

First, download the Kindle desktop software from the official website and install it.

Once installed, log in to your Amazon account, download the books you want to decrypt, find them in their location, and copy them to your desktop (or whatever directory you want).

Kindle for Windows: C:\Users\ Your usernames \Documents\My Kindle Content.

Kindle for Mac: /Users/ your username /Library/Application Support/Kindle/My Kindle Content

In this way, the name of the ebook is generated by the app itself, similarly
B00FF3JVAC_EBOK.azw, it is difficult to identify.

Copy directly from the Kindle device

Connect your Kindle to your computer using a USB cable, find the Kindle directory, and copy the azW or AZW3 files in the Documents folder under it.

Remove DRM from Kindle books

Cracking DRM is as simple as using the DeDRM_tools tool, which is open source and can be downloaded directly from GitHub.

The tool provides two ways to crack DRM, either directly using its Supplied Mac or Windows applications, or using the Calibre plug-in in conjunction with Calibre.

The second method is recommended here, because the first method also needs Kindle device serial number, which is quite troublesome.

Install the Calibre application

Calibre is an open source ebook management app. Details can be found on its website. The installation method is also very simple, directly download the installation file from the official website, and install.

Install the plug-in to remove DRM protection

Calibre supports plug-ins, and it also has a plug-in repository for easy installation of various plug-ins. Calibre itself does not support DRM removal, and the official plugin repository does not provide it.

Go to releases of DeDRM_tools to download the latest ZIP package, unpack it, and find a readme file in the DeDRM_tools_6.5.4/DeDRM_calibre_plugin directory. There is also a Calibre plug-in package, dedrm_plugin.zip.

Start Calibre, click preferences (Mac shortcut, CMD +,), and click Plug-ins in Advanced Options. Next, click “Load plug-in from file” and select the newly extracted dedrm_plugin.zip to install. Calibre has some safety warnings that you can simply ignore and proceed to the next step.

After installing calibre, restart it

The use of plug-in

Once the plug-in is installed, you can simply add the AZW or AZW3 files you want to crack to Calibre. The plug-in automatically converts drM-protected files to their original format.

With raw files, you should be able to push them to your Kindle device or convert them to EPUB or TXT using Calibre.

The other way

In addition to Calibre, DeDRM also provides Mac and Windows applications that can be used to hack DRM.

However, both apps require the Kindle device serial number, which can be found directly in the device’s system information. The location of the Kindle varies from version to version, but you can basically view the device information in Settings.

After you have the serial number, you can open the application and configure it. The process is relatively simple and I won’t go into details here.

Once again, this article is only for personal purchase of legitimate books for reference. Please do not use it to spread pirated books. It is everyone’s responsibility to support legal copies.
