Ways to update your PS4:
1. Connect ethernet cable to the PS4 and download directly. The system will automatically restart and install the file.
2. Connect a USB Flash drive with at least 460 mb of free space. 16+gb drives are very cheap now, so you might consider buying those.
Note: doing a clean install from a complete system file will erase your Playstation. Only do this if you have everything backed up to an external drive and you are ready to continue. I do this when I swap out hard drives for a faster solid state drive.
