Thank you very much for your help. But I'm pretty sure it won't work for me. My PW2 can't be registered (it's a prerequisite for winterbreak, as I see). I think its because its a demo version (I bought from 2nd hand store....).
Thank you anyway.

Maybe.... I may try updating (or downgrading....) to other firmware version (less than 5.18) by hand. But I think I need to disable OTA update hotfix first. I have basic linux skills, maybe modifying some config file or something like that.... and then putting the update....bin file in the root folder.... so it will be detected and then I will can restart the jailbreak with the classic method, wich worked fine.

I'm a literal complete beginner to jailbreaking, and I've been trying for a few days to be able to open KUAL on my old K2i, but every time it gives me the "title isn't signed by a registered developer".
I've successfully jailbroken the Kindle with Niluje's jailbreak and used downloaded launchpad and the custom screensavers, so I think the jailbreak has worked.

I've also tried to download the updated MKK from here, using MRPI and in the Root directory: https://www.mobileread.com/forums/sh...postcount=1295

The way I downloaded KUAL doesn't appear (?) to give me an easy way to update the developer key manually, and I've tried all of the tricks on this forum and others that I can find,

Any help from someone who knows what they're doing better than me would be amazing!

Also my K2i is still on 2.5.8 Kindle version, which I think is it's "firmware". I don't know if that may cause problems.

MRPI isn't used and isn't needed on a K2 (or K3 and K4 either). Custom bin installer on that device are all installed by simply copying bin file into "root" of Kindle removable drive and then after ejecting from computer and using "Update Your Kindle" option.

You don't need KUAL to install new, updated DevCert/MKK. Just copy "Update-mkk-20250419-k2i-B003_keystore-install.bin" and install it using "Update Your Kindle" UI option.

If KUAL doesn't even show in your list of book then you used wrong file or copied in into wrong folder.
(you new to use "KDK 1.0" azw2 KUAL file and place in into "documents").

I got KUAL installed with the documents folder, and have tried putting the DevCert update from here: https://www.mobileread.com/forums/sh...postcount=1295 In my Kindle, but in the 5-something times I've tried it hasn't changed the situation.

Well if you can't get KUAL to work I guess you're gonna need to adapt and run those scripts KUAL extension would run using alternative methods. Like defining a shortcut hardware keys combo in launchpad (or if Kindle 2 firmware had search bar commands maybe defining a custom command to run your script).

What do you use KUAL for? Starting KOReader?

[Wilbot3000]

I'm planning on installing KOReader with KUAL, yeah

Is there a forum that explains how to utilize Launchpad for that?
