A few hours ago, Sony released firmware 6.00 for the PS4. As for any major release, PS4 owners were expecting an update with lots of new features, but it appears this new update only “improves software performance”.
It almost feels like a mistake happened, or Sony are planning something massive that for some reason couldn’t be pushed as part of this update. Many PS4 owners were expecting features such as the possibility to change one’s PSN name, among others. By comparison, firmware 5.0, released last year, had a significant number of new features.
The update is allegedly compulsory if you want to use Sony’s online services.
Implications of PS4 Firmware 6.00 for hacks and PS4 Jailbreaks
As always, if you have a hacked PS4, or a PS4 you hope to hack in the future, do not update it. The lower the firmware, the higher your chances of getting a hack. It is not publicly known at this point what potential exploits this firmware patches.
With that being said, there is to my knowledge no hacker who publicly announced they would release any new hack anytime soon, including on lower firmwares such as 5.55. The latest PS4 Jailbreak works on firmware 5.07 and below (5.05 being more common).
Anyone running on firmware 5.5x, or, now, on 6.00, are currently out of luck, and their best bet is to get a console running 5.05.
