I just bought a PS4 Pro running System Software 5.01 with the intention of jailbreaking it. I am a complete PS4 hacking newbie. I am seeking some advice before I start the hack. Is there any advantage to be staying on a low firmware such as 5.01. Is there another higher up firmware version that is better for jailbreaking? What is the "Golden" firmware version for the PS4? For example, a few years ago the Golden firmware version for the PS Vita was 3.60. I heard of the recent jailbreaking method for firmware 9.0. Should I update to firmware 9.0 and apply the jailbreak?
