The CBOMB has been defused

Sony Has Finally Fixed The PS4 CMOS Battery Issue

Sony has released a firmware update which seems to have fixed the so-called ‘CBOMB’ flaw with CMOS battery issues in the PS4.

The fatal CMOS battery issue was identified by a Twitter user earlier this year. The so-called ‘CBOMB’ issue was created when Sony introduced new measures to stop people manipulating the time and date settings around trophies. 

If your CMOS battery (a small device which keeps track of time in some devices) died and you could not sync with the PSN store, games would be unable to load. As VG247 noted – this issue would apply to both physical and digital games. This effectively put a ticking clock on all PS4s. Every console would eventually become unusable whenever Sony decided to retire the PSN store.

Install the update ASAP

Now PS4 players are reporting that the 9.0 firmware update has fixed the CBOMB issue. When Modern Vintage Gamer tested this, he was able to play games again once he’d installed the firmware update. 

This is a welcome move by Sony – extending the life of the platforms and fixing a feature which would have forced obsolescence for millions of consoles around the world. Hopefully this sets the tone for all console makers.
