You can download the latest firmware here: https://www.playstation.com/en-us/support/system-updates/ps4/
Stick it on a usb stick, so if the game requires you to have latest firmware installed (as some do), you can just install off the usb.
I'm just saying that, because if my experience is anything to go by, it'll be a Christmas miracle if you manage to get everything back in that box again.
