For what I have seen there are no progresses whatsoever in the jailbreaking scene for the PS4. Possible Sony won the final battle ? Not even one year before the release of the PS5 and still the PS4 is a massive stronghold nobody really managed to breach completely and ultimately. I am impressed frankly as someone that works in Internet security how well protected a videogaming console is. On the Internet there are thousands of network services and operating systems with a ton of exploitable bugs while the PS4 stands over all of them tenths of times better protected. Incredible imho. We are talking about a gaming console not a web server or db server that serves million of requests a day ! Either hackers are not really wasting their time in even trying to make a progress with the jb of the PS4 or Sony really made something remarkable protecting their device.
