Having the same problem as a lot of other people on this thread.

I had the "KUAL permissions have expired" problem, which I understand to be due to expired certificates.

I updated the DevCerts from the binary in https://www.mobileread.com/forums/sh...postcount=1295, which I now understand will not work properly on my Kindle DX Graphite. I now get the error "The title is not signed by a registered developer."

If I understand correctly, the only answer to the original problem is to reset the clock to a time before the certs expired. I'm not sure I want to do that, it's going to play havoc with the "most recent" dates in my documents.

But first, how do I undo the DevCerts update to get back to where I was at the beginning?
