Tutorial for backport ??? Yeah sure!
Update your PS4 on the firmware 9.00 and you never need
a backported file or wait after it or inherit of the problems you can
have with it.
It's the best tuto i can do for you and all the others
who stay in 5.05.
I never liked the method.
It is useful only for backported a file higher than the current hack available like
an update needed the v9.03 (Exemple) and backported to be able to use it on firmware 9.00.
There, it's useful!
(But at the final, it's your personnal choice but i not impose to me to work more for this(Tutos, pkgs or whatever), sorry.)
