Device: Kindle gen 4
I factory reset my 4th gen (4.1.4) - Successfully jail broke it, then followed the guide from the start once more and when I tried opening KUAL get the "this item is not signed by an authorised developer " message that has been detailed over the past 5 or 6 pages.

So I downloaded the DevCert bin file (K4-ALL) dumped that in the root of the kindle and updated the device - No change.

Part of the problem, for me at least, was it's easy to get lost when the guide links to other threads on the forum to download files. Whet would be nice would be a single zip file that contains just the files needed for that one model / firmware, with detailed install notes for dummies... It's so easy to miss a step, or copy the wrong file to the wrong folder and screw things up. Whilst some of you guys are very savvy with this sort of thing, with lots of youtube videos mentioning the way to brake free from Amazon, a lot of people with little or no experience of unlocking their kindles struggle.

Anyway... any pointers on how to get passed this message and get KUAL working would be appreciated
