WinterBreak2

Any sufficiently advanced technology is indistinguishable from magic.
- Arthur C. Clarke

WinterBreak2 is a browser-based jailbreak created by Scam.Net and Penguins184. It was made as an alternative to WinterBreak / Mesquito for situations where those methods are problematic.

Unlike WinterBreak, WinterBreak2 uses the Kindle’s built-in Experimental Browser instead of the Kindle Store, which means:

  • Your Kindle does NOT need to be registered with Amazon
  • It works on blastlisted devices (devices where the Kindle Store exploit has been blocked)

WinterBreak2 only works on firmware versions below 5.16.4.
If your firmware is 5.16.4 or above, you will need to use a different jailbreak method.

Prerequisites

  • You will need a PC
  • Your Kindle must be on firmware below 5.16.4
  • Your Kindle must have a valid, internet-connected Wi-Fi network saved
  • Your Kindle’s storage must be almost full, with only 50-90 MB of free space remaining to avoid automatic updates
  • File archiver software to unzip files (7-zip or WinRar for Windows)

If you face any issues, please check the troubleshooting section

To prevent your Kindle from automatically updating during the jailbreak process, it is critical you follow this guide before continuing

WinterBreak2 only works on firmware versions below 5.16.4
For firmware 5.16.4 – 5.18.0.2, use WinterBreak
For firmware 5.18.1+, use AdBreak

Extract WinterBreak2 to your Kindle

Plug your Kindle into your computer

Extract the contents of wb2.zip to the root of your Kindle's storage

You should see the files jb.sh, patchedUks.sqsh, and a winterbreak2 folder on the Kindle's root

Eject & Connect to Wi-Fi

Safely eject the Kindle from your computer

Make sure your Kindle is connected to a Wi-Fi network

Open the Experimental Browser

On your Kindle, open the Experimental Browser

You can find it under: Menu → Experimental Browser (or Settings → Device Options → Advanced → Experimental Browser depending on your firmware)

Navigate to the following URL:

https://winterbreak2.now.sh/

Run the Jailbreak

Press the Jailbreak button on the page

A dialog will open and the jailbreak process will begin

Wait for the process to complete

Done

Once the jailbreak has completed, turn Airplane mode on and continue to the post-jailbreak stage

If present, delete the update.bin.tmp.partial file from your device to prevent an automatic update

Troubleshooting

The Experimental Browser won’t load the page

  • Make sure your Kindle is connected to Wi-Fi and has internet access
  • Try typing the URL carefully: https://winterbreak2.now.sh/
  • Reboot your Kindle and try again

The jailbreak button does nothing

  • Ensure you have correctly extracted the wb2.zip contents to the root of your Kindle
  • Verify the files jb.sh, patchedUks.sqsh, and the winterbreak2 folder are on the Kindle’s root directory
  • Reboot and try again

Still having issues?

If WinterBreak2 is not working for you, and your firmware is below 5.16.4, try the original WinterBreak method instead (requires Amazon registration).
