About five or so months ago, you might remember that the PlayStation 4’s internal CMOS battery was a bit of a fuss and how it should die alongside Sony’s ultimate drag. PS Shop support on the console, would effectively render the system useless. The small component in question is used to unlock date and time Trophies on PS4 to prevent any cancellation, but while the battery will be easily replaced, you can’t access the battery unless you can connect with PSN after installing a new one. your games more – physical or digital. That’s because PS4 titles have to connect to the network at least once before they can run.
This has created a bit of concern among the Playstation hardcore community, with some worrying about what would happen to current PS4 titles if PSN support and the CMOS battery in question were to die. Well, the good news is that this concern is not a problem at all as Sony has fixed the issue with the recent 9.00 firmware update.
YouTuber Modern Vintage Gamer investigated the claims after tweets were sent out by members of the public and the video embedded above was released. MVG removed the CMOS battery below PS4 and downloaded the 9.00 firmware update, then disconnected the system from the internet when it was successfully installed. Whereas before the game would immediately display error CE-30391-6 and refuse to run any PS4 titles, the console now successfully hits the game and enables playback. Note that the PS4 Trophy did not deserve to be shown, however.
To double check, MVG then inserted a PS4 disc and downloaded and installed Shadow of the Colossus from scratch with the CMOS battery removed and the console disconnected from PSN. It still worked, which means the problem is completely solved. “We are 100 percent certified that it works,” MVG concludes.
