PSA: Do Not Update Your PS3!
Don’t update your PS3! The newest firmware update seems to be causing mass bricking of consoles. Disable your internet functionality and stay safe.
It’s not universal by any means, but the reports of bricking are widespread enough to cause worry.
The timing of a bad firmware update is a bit auspicious, though, after Sony came out of E3 on a tidal wave of positive success. Just goes to show Sony can still screw up.
