Hi
I know this will have been answered already but navigating the forums is literally like learning another language for me! I am gutted that the kindle I love has got the boot from darth bezos and I can no longer download millions of books to read over the holidays.
I have successfully jailbroken by device (or at least that's what it told me) I downloaded the kidlet kit and then the KUAL but when I try to launch the KUAL i get an error message I know will have been seen before.
I can't work out what i did wrong. I have checked my nickname, unintalled and reinstalled the K4 kidlet from the dev certs file and then tried to launch the KUAL again. No joy.

Is there anyone that can help and explain it to me as if to a very small child. Think of it as community service - helping your elders!
