Tools Sanctuary - Jailbreak for ANY Kindle model, FW 5.16.4 - 5.18.3 (inclusive)

[sparklerfish]

Sanctuary is a new browser-based jailbreak by Ava, Alysa, and me (sparklerfish).

KindleModding step-by-step guide with screenshots can be found here.


REQUIREMENTS:

• A Kindle (any model) on firmware version 5.16.4 - 5.18.3 inclusive (5.16.5 may specifically be an exception due to a WebKit browser experiment; if you are on this version and the website/id doesn't load properly, please update to the next jailbreakable firmware to ensure you are on a Chromium browser)
• A wifi connection
• Patience :)

NOTES:

• Registration is not required; this works on blacklisted kindles.
• The entire jailbreak process is on-device, no computer required.
• The entire process DOES require wifi, so ensure your storage is filled to prevent updates!

GUIDE:

1. Open the Kindle web browser and navigate to http://sanctuary.skyvincent.com (ensure you have typed "http"; "https" will not work).
2. Wait for port scanning to conclude (maybe grab a coffee or a snack; if you're unlucky with your randomly-assigned port and on an older Kindle this could take 15+ minutes).
3. When the id appears, copy it exactly into the text box below. Any 0's you see are zeroes (it is hex). You do not need to manually capitalize letters; they will be automatically capitalized for you. And yes, this is the only way to do this. Blame CORS.
4. Click "Connect". If nothing happens, verify that you have typed the id exactly correctly.
5. Wait as the webpage performs some operations and downloads some files. You will see several popups informing you that files were downloaded. Just click ok on these and keep chillin' until the downloads complete and the page changes to the "Downloads done!" message.
6. Close the browser, open the Kindle 3-dots menu and go to Settings -> Help -> Get Started
7. You'll see some text/logs onscreen as the script runs and probably an "Application Error" popup. This is fine, just click ok.
8. Go back to your homescreen and you should see a "JAILBROKEN" document in your library verifying that everything succeeded!

This jailbreak leverages the latest jb.sh from KindleModding, so you do not need to manually install the hotfix or rename OTA binaries after jailbreaking; it is all handled for you along with the jailbreak script.

Happy jailbreaking!
