Hi guys! I have an idea to downgrade ps4 system 6.00+ to 5.05. so we need a 6.00+ update and 5.05. i think it would be possible to exchange the values of the two version that the system would accept the update as a "newer" update. And instead you would get the update 5.05. Im not so smart to do this, but i believe that someone is smart enough to do this kind of stuff.
