PS4 firmware update 2.04 is now live but there is a problem with it and many users are unable to download the update as it ends in an error or keeps randomly stopping.
It is advisable to not download the update as something seems to be wrong. If you manually go to settings and click on system software update you may get an SU-30709-9 error. If you do manage to start the download it may fail and give you CE-32937-4 error.
You can try to disable “connect to network” option in the settings and then try the download again, or just wait a few hours.
The firmware update doesn’t seem to add any new features and just seems like a stability update according to the changelog.
We will keep you updated once we hear more on this.
Update: The issue seems to be have been resolved for many and Sony has commented as well.
Update: Some players are reporting PSN issues — our engineers are on the case and investigating.
