Looks like your PS4 is looking for the initialisation software. There are two options for downloading firmware from the PlayStation support website. One is a firmware update and the other is the full firmware package, both are called PS4UPDATE.PUP. You need the full firmware file which is a much larger file than the update, around 2GB I think. Beware though as this firmware performs a full reset of the PS4 which means it will wipe everything off the hard drive.
