Installation Guide

Before Jailbreaking...

Warning!
Jailbreaking often involves connecting to the Internet. Before beginning any jailbreaking process, please remember to fill up your Kindle as to avoid ruining the jailbreak mid-process. Additionally, please ensure you have read this before you start.

If you have done the above, please commence to the next step.

Download

Download Ads

Leave your kindle for a while, connected to the internet, so it can download advertisements.

If you press the lock button, an advertisement should be displayed.

If advertisements aren't being downloaded after a while, a factory reset may help.

Aeroplane Mode

Once you have verified ads are displayed on the lockscreen, enable airplane mode.

View all ads

Click on the top right menu and select "View all ads", which should display multiple "special offers".

Copy .assets

Plug in the Kindle, open the system folder and copy the ".assets" folder to your computer.

Unzip AdBreak

Unzip the previously downloaded AdBreak, and place the extracted contents within the ".assets" folder located on your computer.

Run The Replace Script

Windows:

Double-click on "replace.bat" to run it.

MacOS/Linux:

Run find . -name 'details.html' -exec cp adbreak.html {} \; using a terminal.

Replace Kindle .assets

Delete the original kindle .assets and replace it with your on-PC modified copy.

Jailbreak!

Unplug, click on an ad and go through the popups, once you click Close on "Bang!", the jailbreak script should run.

You can safely ignore any "application error" popups, they are irrelevant.

Troubleshooting

Common Issues

  • Can’t find the system folder:
    • On mass storage kindles, if you cannot see the system folder, you will have to navigate to the path manually, or follow this guide to see protected system folders.
  • “Bang!” shows but the jailbreak doesn’t run:
    • Check the .assets folder on the Kindle. “jb.sh” and “patchedUks.sqsh” must be in there.

  • Switch account region
    • Go to Manage Your Content and Devices → Preferences → Country/Region Settings → Change.
    • Select one of: US, UK, DE, FR, IT, ES, JP, CN, AU
