Thanks. Managed to do it for my Kindle Scribe (1st generation) on 5.18.5.0.1

The steps I did were:

1. Registered for a temporary Amazon.fr account
2. Set Amazon.fr's account address and payment details to be some FR address
3. Deregister my Kindle Scribe from my Amazon.com account
4. Register the Kindle Scribe to Amazon.fr account
5. Turn on ads for Kindle Scribe in Amazon.fr account
6. Send a book to the Kindle Scribe to trigger Ad
7. There will be a single sponsor Ad on the home page
8. Put Kindle Scribe into airplane mode and start jailbreaking
9. For Adbreak package, I downloaded the latest (v1.1) from https://github.com/KindleModding/AdBreak/releases
10. Triggered the sponsor ad in main page and it should ask for WiFi followed by the start of jailbreaking
11. Installed Hotfix
12. On the Kindle Scribe, deregistered the device and re-registered it to my Amazon.com account
13. Continue with KUAL onwards
