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!
