I went to the shops earlier today to only come back to find my brother playing with the power cord of my PS4 while it was turned on. I have no idea what he has done but whenever I turn it on it comes up with the following message
Connect a USB storage device that contains an update file for reinstallation for version 4.06 or later.
You can download the update file for reinstallation from playstation.com
I have done this with a blank USB that contains only that file. I NEED it fixed in 10 hours and I have no idea on what is even causing this. If anybody has even the slightest clue on what is happening and what has happened please tell me.
