PS4 jailbreak / CFW?

There's a PS4 jailbreak ver. 7:00?

I'm new, and only find fakes and scams. I know there's a WebKit exploit for 5.06 (version should have been something with 5.) but otherwise I'm pretty unsure.

Does someone have one or doesn't there?

Many thanks

PS.: No, I don't want to download games for free or anything like that. I saw a lecture that got Linux up and running and I think it would be pretty cool to have it 😅

Having linux is always pretty cool
