New to all this and I promise I've done some hunting around for a sensible answer, but there are many different opinions. I've just scored a PS4 slim on firmware 4.5 and am not sure which firmware to jump to in order to jailbreak it. I'm thinking maybe 7.00 after watching Modded Warfare's latest how to video which means I can do the modern Goldhen with just a USB stick but still have room for maneouver as far as further updates go if required.
