Announcements & Updates

A new jailbreak by hhhhhhhhh has just been released! It targets Kindle firmware 5.16.4 to 5.18.6 and works on blacklisted and registered mass-storage Kindles.

It has been confirmed to work on 5.18.6 with PW5(SE) and KT5. KOA3 was listed as untested in the guide, but community reports indicate it can trigger on KOA3 running 5.18.2.

Unfortunately this will not work on any MTP devices, such as PW6/KT6. Amazon is already patching the exploit via firmware updates, so enable Airplane Mode immediately to avoid silent OTA updates closing the window.

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.

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.
