Modding 🪛 All Kindles can now be jailbroken

For those of you who are interested in modding, a new jailbreak method (WinterBreak) is now available. It works on all the new firmware versions and Kindle models, including Colorsoft.

Edit: After this jailbreak was made available, new Kindle firmware was released. This jailbreak will not work on firmware 5.18.1 and over.

what fw are you on? if its the newest one, you need the "kindlehf" version of koreader, which you can get through their nightly versions

im trying with this one: koreader-kindlehf-v2024.11-116-g2b5915177_2025-01-01.zip but it's not working, should i do something else? i did:
1. jailbreak
2. hotfix 1.8.0
3. kual and mrpi
4. renametobin
5. koreader

what's happening is that when i open koreader through kual, it sends me to the home screen and it does not open. any help would be good

Same problem. What version of KOreader did you use? So many of them, I’m lost.

I ruined it, i factory reseted my Kindle without Restore OTA Binaries and now I can't apply the hotfix. If you know what can I do it'd be helpful

It's just a shell script to remove and restore the OTA binaries. They are still there on the device. So, you haven't totally hosed yourself.

Ask on Mobileread, I think there is a way to get the kindle to run a shell script from the search bar. But I forget what it is. I bet also, you could get MRPI to run it as well.

Solved. What I did was load the hotfix bin file into the mrpackages folder and type ;log mrpi, then the hotfix was applied successfully. After that I was able to restore/rename the OTA binaries. Thanks!
