you can add to that list FW 6.72, where all except that new about permanent hen, is the 100%. And it is the only one.
Anyways i wonder about that 'permanent hen'. How it can be possible ?
the fw updates payload is not reverting on each boot like someone said before. That only happen when a KP happened and the system file checking is performed.
^ tracing the 9.00 exploit, i have found that is very dirty. Once you control it to avoid OOMs, you will find that userland will also fail a lot. And even from that, sometimes more OOMs will happen out of control.
But certain stability can be achieved with some work on it.
I have pending to...
^if the FW 7.55 is added, the benefit can be brutal. Just remember guys, in PS4 the lower FW, the best
When the exploits on that FW are loaded, with blood, the behaviour is exactly the same as 6.72, solid rock.
