By sandeep koyya on Sep 17, 2016: #1 Hi Team, I've found a notification in my ps4. It says ps4 update 4.0 downloaded ready to be installed. My current firmware says it is at 2.56. I have made relevant settings like turned off auto download. I have never updated i.e pressed update later when it asked for update. Does it mean that my chances of having future jailbreak is over?
