Official release & resources

Release at a glance

Release date: 24 Sep 2025
Maintainer: @hhhhhhhhh
Exploit base: CVE-2012-3748
Supported firmware: 5.18.1 – 5.18.5 (some micro-patches may block the exploit)
Requires: Special Offers (ads) active on the lockscreen

Prerequisites

PC + USB cable (you will copy/replace the device .assets folder)
Kindle must be registered and not blacklisted
Kindle must display Special Offers (ads) on the lockscreen
Device firmware must be in the supported range (see above). If ≤ 5.18.0.2, use WinterBreak instead.

Do not proceed without verifying the above—especially the presence of ads and correct firmware.

Quick install checklist

Download the latest AdBreak package from the official release page.
Confirm ads: keep the Kindle online until ads appear on the lockscreen. If no ads appear, a factory reset can sometimes help (see Troubleshooting).
Enable airplane mode after ads are visible.
Open lockscreen menu → View all ads to confirm multiple Special Offers are listed.
Copy .assets – connect Kindle to PC and copy the device's .assets folder (backup the original).
Unpack AdBreak and merge its files into the copied .assets folder on your PC.
Run replace helper:
- Windows – run replace.bat
- macOS / Linux – run the provided terminal command to place the exploit HTML into matching ad folders (example in the release)
Replace device assets: delete the original .assets on the Kindle and copy the modified folder back.
Trigger exploit: unplug the Kindle, tap the modified ad, follow prompts; the jailbreak script should run at the final popup.

Backup your original .assets folder and any data before modifying anything.

Enable Special Offers (if needed)

If your device shipped without ads you can often re-enable them via your Amazon account:

Amazon → Manage Your Content and Devices → Preferences → Country/Region: select a supported region (US, UK, DE, FR, IT, ES, JP, CN).
Add a matching billing address and a payment method (card required; usually no charge).
Enable Special Offers for your device and sync – ads should populate the lockscreen after some time.

Important: Kindle Scribe and Colorsoft cannot be made ad-enabled and are not compatible with AdBreak.

Troubleshooting & key cautions

Ad removal: AdBreak does not remove Special Offers. Use separate scripts if you want ads removed after jailbreaking.
Unsupported models: Scribe & Colorsoft cannot be jailbroken with AdBreak.
Firmware issues: some 5.18.5 micro-builds (e.g., 5.18.5.0.1) may block the exploit – check community threads for workarounds.
Hidden system folders: mass-storage Kindles may hide the system folder—follow a device-specific guide to reveal it before replacing .assets.
Factory reset: can force ad downloads but will erase personal data—only use if you understand the consequences.
Always keep backups: preserve the original .assets so you can restore the device if needed.
