I have followed the jailbreaking tutorial for my kindle 4 NT on the kindle modding wiki, all the wa through and when I try to open KUAL, I get the error "Mobileread Kindlet Kit is not installed". I have then tried to install MKK, but everytime I try to install, using the K4 ALL bin, I get a U007 code error when tring to update. I've tried starting the jailbreak from scratch but still had the same issue. My kindle is registered and I've been doing this with airplane mode on.
Any help will be greatly appreciated!
