Kindle Hacks
Won’t Work on 5.13.4 or higher
you should try serial jailbreak
Run a custom Configuration:
Click Jailbreak Method (don’t work anymore)
- Jailbreak ?(getting unlocked ! & installing custom hacks
Jailbreak
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.
- 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
- Now reset your Kindle then start again
Check here your device version here & if on factory FW version
PW4 2018/2019 (When on factory firmware)
It seems like there might be an issue with the latest firmware patch causing the failure, or there could be something that was not done properly. Let’s try to troubleshoot to identify the specific cause of the issue.
Send Serial Number
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)
latest JB available at Snapshot mobilereads all Universal Kindles
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
YOU SEE THIS THEN YOU ARE SUCCESSFULLY
Applications
Once you have a jailbreak, the rest is mostly installing packages via MRPI
Latest builds of Hotfix comes with MRPI too so no need to install MRPI again. (Make sure to stick with latest builds)
I keep a ready directory of packages I can use most of it just being koreader.AsDefault
KO reader is a FOSS document viewer for E Ink devices that supports Kindle, Kobo, PocketBook, Ubuntu Touch and Android devices.(Specially for KOBO reader)
The primary 2 packages are:
Update_KUAL-f54e864-.bin
update_kpvbooklet_0.6.6_install.bin
Run ;log mrpi via search after copying them to re-install them if needed.
koreader(installation)
Download the latest release from GitHub.
Modern Paperwhites = kindlepw2 package
Unzip it to the copy files to root directory
& Voila
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.
HIGHLY RECOMMENDED
If not familiar with plugins and Calibre don’t worry you can use Epubor Ultimate without hassle (same for mac)
