It asks for my USB with update 4.73 or higher and then won t accept the data on it, even though it s up to date, then the system shuts off. I tried booting it into safe mode and downloading the update via Internet and tried going onto the system but I got the same thing again checking system storage insert USB etc... I tried to initialize the PS4 with safe mode which worked but then the PS4 froze and shut down and when I turned it on again I got the system storage error. Any help would be great this happens Everytime I try to use it. How do I Fix This?
