What's going on at my ps4?

I played my round nicely, when suddenly my ps4 went off. Then they started up and it worked. However, she has gone out completely again as if you had pulled the plug. Can also be that vielelicht the current had short-term problems.

Anyway, now comes the reboot the message that booting is not possible and that I need to connect a USB storage device to install an update.

Does anyone know what I should do exactly?

Get a usb and plug it in and do the update file

maybe that will help

You need a USB stick because you load the file down on the PC and then you stick the stick in the ps4 and reinstall the system.

Has the following for my hard drive or other?

There must have been some serious mistake. Apart from the fact that also a hardware defect can be present, I would follow the instructions.

When reinstalling the system software, you usually lose all data.

So I loaded it on a usb stick but it is not recognized somehow

Is it a problem if on the usb stick other data on it are. So I have to have the folder PS4 completely alone on the USB?

First, you have to stick to the given folder structure. If there's any data on it, it should not matter. On the other hand, you have to make sure that you have downloaded the complete software, not just the update.
