I know what I do, be shure ... and my Kindles are all modified. But I also know, where they end up with their questions and cry for help.

And you have already seen how quick some advice is done, being shure yourself, you have done well. No offense against anyone trying to to his best here. But going back to an older firmware is not as easy as you are giving the impression. I had Kindles to "resque" where people promised having done nothing else than following instructions.
