@Vlad1101,
There is a way to downgrade a PS4 Console by using the official JigKick, but since no one has access to the tools. It wouldn't have a chance to be leaked or shown.
In addition, Sony has added more protection to Private Keys so now you can't use the ghetto cheap dongles. You need the official dongles to break their security.
Hope that answers your real question sir. Please respond back to me if that has answered your question. If not, I'll close it myself in two days.
Cheers, Hydrogen
