PRC DRM Removal for Kindle Android Books

Posted by on .

AZW is the format of Kindle eBooks purchased from Amazon store. Usually, if a Kindle Android App users sync the purchased books into their Android phones, those books will be PRC format.

But if you can't directly use Kindle DRM Removal to decrypt them, and you cannot even remove DRM from them with serial number because the Kindle DRM Removal has no clue for decrypting your PRC books exported from Kindle Android app.

This article is going to tell you the two correct ways to remove DRM from PRC files which exported from Kindle Android app.

Update on 2015/3/27: All the content in this article has been covered in another post about DRM removing for Kindle, which contains removing DRM from Kindle PC/Mac, Kindle eReader, and Kindle Android app. You can read that post to get more information on this topic.

Method1: Remove PRC DRM with Kindle DRM Removal

1Get the tool ready

To remove AZW3 files DRM, you only need two programs:

1. Kindle DRM Removal

Click the buttons below to directly download the tool then install it.


2. Patched Kindle Android app

Click the link above to download it and please use this patched app to replace the official version on your Android Phone.

Only with this patched Kindle Android app we can get the clue for removing DRM from PRC files.

2Find the PIDs of your Kindle Android books

Run the patched Kindle Android App and ignore any warning from some cellphone security apps, this patched version changed some codes upon the original official version, but it definitely won't harm your cellphone.

Login your Amazon ID and sync purchased Kindle books to local, randomly open some of them to generate the PIDs which would help us decrypt PRC files.

Enter "Info --- About --- PID List" to check the PIDs.

Click "Use Kindle Serial Number (or PIDs)" and input the PIDs in the blank, we've already got the number in step 2.

If you don't know where you can find the Kindle Serial Number, you can read the full guide on How to Easily Find the Kindle Serial Number.

Note: There might be several PID digits displayed in your Kindle Android app, please input all of them into the blank (one by one) and pay attention to the case shifts.

Click "OK" to confirm the setting and here comes the last step, "Remove DRM".

Method2: Remove PRC DRM with Android DeDRM

In addition to method1, there is an easier way to help you remove PRC DRM. It's a tool called Android DeDRM. Compared with the method 1, it has following advantages:

1. No need to install patched Kindle for Android APK.

2. It can deal with all versions of Android.

3. No need to add books by yourself, it will find PRC DRM files automatically and remove DRM quickly.

1. Make sure your Android devices(cellphone or tablet) have been rooted before removing PRC DRM.
2. Your Android devices' operating system is preferably native Android OS. If it's customized Android OS, such as Kindle fire OS, we can't guarantee the tool will work on it.

Now, let's remove PRC DRM with Android DeDRM.

First, download and launch the tool. Then connect your Android device to computer with USB. When you see "Your device has connected" , just press "Y" on your keyboard.

Press "Enter" to continue removing DRM. Then your PRC DRM protected books will be copied to the local devices soon, just wait a moment until you see "xx books' DRM have been removed". Finally, press any key to exit.

Now all your DRM PRC files are decrypted successfully. With this method, you can remove DRM from PRC files without having a Kindle device or Kindle for desktop applications. In another words, you can remove Kindle DRM from Android tablets and phones.

First and foremost, thank you for the guide!

The app seems to just crash on start up on Android 4.4 and above, is that correct?

05/29/2014 04:28:45
Does not work at all for me. I have followed all the steps, located the PIDs, entered them, and get the message "Can't find correct PIDs".
06/5/2014 01:20:33
The app crashes for me as well. :/

08/1/2014 11:27:18
Same for me with Android 4.4.2 KitKat! The app crashes. Does somebody released a patched version of the latest Kindle app?
08/10/2014 20:43:28
I'm keeping for an updated solution for Android 4.4. If there is any progress I will update this post.

01/23/2015 00:31:32
Got it !!! just get a full fonctionnal version with PIDs listing !!!
05/29/2015 11:39:29
Could you upload your patched kindle to share it with US?
02/15/2015 23:42:57
Who originally developed this method? Why are they not keeping it updated?? Amazon now blocks downloading to K4PC for a lot of books, so we need an Android based DeDRM tool now.
02/16/2015 02:40:28
The original scripts is developed by Alf Apprentice, and the problem is, you need combine this script with Kindle for Android APK file.
03/1/2015 06:54:29
over Aptoid XOMMIT-Store Kindle is funktionary (PID is added) and without an virus.
but please scan every time from unknown sources.
PID can u see after open the book on menu-info-info-PID List.

That Epubdor Removal thing isn't free. Would have been nice to disclose that.

I have the EPUBOR for removing DRM, and everything works fine on my Kindle Fire--older version 1.
However, I have several books showing PRC format only, and they won't decrypt.  All were purchased directly from Amazon, and sent directly to my KF.

I've read the guide for removing DRM via android devices, but these books were never on an android.

Hi, the patched kindle app doesnt work on android lollipop and would not logged in on my ICS either. Any update?


09/20/2017 15:16:48
We do not suggest you remove the DRM from the Kindle for Android device. If you have the computer, please try to download the Kindle for pc/mac. Then run Epubor software to remove the DRM. You can read this guide: https://www.epubor.com/prc-drm-removal-for-kindle-android-books.html
