As its known to everyone few months back Amazon discovered a vulnerability on its kindle devices known as k-drip(KindleDrip).

If you’d like to Jailbreak your kindle please read instructions here.

Long story short it wasn’t a major issue as people try barely connecting to internet as to save battery and only uses to download books or updates. The patch also closed this way one of the most easily available Jailbreak method. Jailbreak capability was identified long time ago which was a diagnostic tool was slipped through the cracks of factory firmware will also allowed to downgrade. It’s sad that they fixed it as of what they claims it to be but the fact still remains at large how will they be able to protect all the devices already being affected as they cannot remove the person having root access unless the send remote reset command.

Kindle Hacks

In case you want to convert an unsupported file format to kindle supported formats without going to manually convert these files:

This hack is essentially helpful when you switch from different device like the ones which uses epub or other formats.

  1. Try renaming your file by changing it’s extension like filename.*** to .png format
  2. Now I want you to understand you have to send file via mail to your kindle address

While you sit back waiting for your files to appear the AMAZON SERVER will simply convert your file to .mobi or .awz format.

Moving onto Jailbreak which is almost impossible to work on 5.13.4 or higher try newest Jailbreak method

Try latest Jailbreak for devices<=5.14.2

Run a custom Configuration:

Click Jailbreak Method (don’t work anymore)

  • Jailbreak ?(getting unlocked ! & installing custom hacks

The official guide on how to jailbreak your kindle here is as good starting point. The mobileread forums have the definitive guides (Password is ilovejedd). Also see this FAQ on the mobileread wiki.

(Most of these only cover modern paperwhite kindles)

Sometimes, Kindle firmware updates will break the Jailbreak(use emergency.sh to restore JailBreak).Search for your firmware on mobileread forums. See this link.

Do at your own risk as said earlier if you have a newly bought device or you don’t like updating your device then You might be lucky.

  1. Backup Documents folder(simply make a copy of that folder) + Don’t copy folder back to Kindle unless you are back to same firmware version with which you backup was created
  2. Now reset your Kindle then start again
  3. Check here your device version here & if on factory FW version

Know your serial

Jailbreak Devices
PW4 2018/2019/Kindle Kids(When on factory firmware)

Drag/Copy the .bin file to your kindle root directory and trigger a manual firmware downgrade update(UYK).Go to the Kindle Menu and click “Update”. If it is greyed out, check if the file was copied correctly, and try rebooting.

*If it fails then it is due to latest firmware patch*

Send Serial Number to mobileread
kindle-jb-factory-1.3-r16160.tar.xz (extract using RAR 5 OR 7ZIP)

Copy main-htmlviewer.tar.gz to the Kindle root directory. (i.e., /mnt/us)
In the search bar, type ;installHtml and press return.
If the screen flashes and the device reboots, the developer key file is now
stored in /etc/uks.
A “You are Jailbroken” document is also created on success

Yes, one very important thing is to install hotfix so your Jailbreak is does not broken on updating software (bridge).

Applications

After jailbreak soon you’ll need other applications to move forward and utilise the ultimate benifits of jailbreak

And that would be KO READER which will be possible only after MRPI & KAUL applications only.

Talking about Nodrm

There are much better websites that explain the issues with DRM, so go visit: fckdrm.com, DefectiveByDesign.org, or EFF/drm.

The primary tool for stripping DRM from Kindle books is apprenticeharper’s DeDRM Repo which works as a Calibre Plugin.

Stripping DRM (AMAZON)

Install Kindle for PC (v1.17 or v1.26) launch it, and download the book.
Go to ~/Documents/My Kindle Content

Add books to calibre after installing kfx.input and drm plugin v6.8

Run calibredb add book.azw. If all goes well, the book should show up in your library, and you should be able to convert it.

Or you can just try Epubor Ultimate

If it doesn’t work, just letting me know, it’s not you. It’s how I confuse with my writing, as the publication is my first.

Thanks for reading
