Firmware Update Kindle 5.19.2 software is available

Firmware 5.19.2 Update (11th Gen and Newer)

Initial concerns were that 5.19.2 might carry over hardened security changes seen on KS3/KSC in 5.19.1, which could have broken hotfix preservation behavior and delayed future jailbreak progress.

Follow-up testing later found impacts were limited: hotfix still technically worked in testing, and the specific hardened security concern did not appear to be copied to other models.

Recommendation is still to avoid updating when possible, fill storage if not jailbroken, and verify OTA binaries are renamed correctly if already jailbroken.

January 2026 - Ladies and Gentlemen, we got em.

5.19.1 for the Kindle Scribe Colorsoft and Kindle Scribe 3rd Generation was exploited by scam.net, approximately one month after these models released.
Huge shoutouts go to:

@hhhhhhhhh for discovering one small part that ended up being the key to this exploit being possible
@kluyg for testing the code on their personal Kindle Scribe 3rd Generation, and being willing to help me test the updated version a week after my first attempt failed spectacularly.

Please do not bother any of the above people, or scam.net, for access to the exploit. You will not get it early.

Much work has to be done to turn this into a functional jailbreak, as many things have been changed by amazon so much existing code no longer works, but a jailbreak will probably be made from this at some point.

Amazon themselves only initially claimed "next year" and now "later this year" for UK and Germany. Any other timeline claims I've seen were from unreliable outlets.

they fixed yellow color thing in color kindle after users reported it.
some features are slowly released to the world over time.

None of that alters the facts that Amazon won’t release the Scribe Colorsoft outside the USA.

So we can expect the Scribe Coloursoft around Christmas then

For what it may be worth, I'm still waiting for Audible to support audiobooks on a Kindle in Canada. It's been six years since I first queried Audible Canada about support for Kindles. I've quoted 2 of the responses.

I would like to let you know that at this time, Kindle devices are not supported in Audible.ca though they are supported in Audible.com (US). Hence audiobooks can't be accessed on Kindle, Fire tablets in CA marketplace.

We are always looking to expand our compatible devices catalog but since an extensive technical testing is required to perfect the final platform it may take a bit longer than expected to release a supported platform but we really do appreciate your feedback in this regard.

At this time, "Kindle" is not compatible with our Audible.ca software.

We are always looking to expand our compatible devices catalog but since an extensive technical testing is required to perfect the final platform it may take a bit longer then expected to release a supported platform.

Although Audible Canada does not currently support all of the same site features or offers you were familiar with on Audible.com, we are working hard to create a customized, unique Canadian experience. Many of your favourite features are in development and we hope you'll stay tuned!

One has to feel some pity for the American and other customers forced to accept software that has not undergone extensive technical testing to perfect the product.

It does appear that Amazon make some very strange business decisions

Agree. Implication is that it will take time for the device to be available outside USA. And by the time it is available, we would be running behind their next device they announced

Were they ever broken at some point?

There have been some issues with side-loaded fixed layout KF8, and even with same downloaded from Amazon.

But I do not know if that is what JSWolf is asking about.

Really! Do you have a source/more details about this anywhere? A small number of Kindle Comic Converter users have been reporting issues recently too which outputs fixed layout KF8 from kindlegen. the problem is that enormous margins are added to fixed layout content top to bottom when it was previously fullscreen top to bottom.

Yes, I saw this with one of my fixed layout Amazon books, but I don't remember which one now and that was before the latest update so I don't know how to reproduce it.
