This got me scared that it could happen to me, since I also share sometimes my PS3 with familly, so I wonder, is there away to deactivate such notifications or change them?
Edit the PARAM.SFO for every game above your CFW version , to at least FW version 03.40 or less on new games .
Never run game from disc ,it has a update PUP AKA - official Firmware on the game disc.
Disconnect from the internet.
Install a Spoof if i 355 ,find a spoof as high as 431 or 999 spoof.
Those are a few things . Running from DISC can get anyone easy if they do not know what they are doing .From a game DISC is the most simple way for someone to updated the PS3 . Simple as starting the game & pressing
& it is over ,if the game is above your CFW = firmware..
Disable automatic updates in system settings is it is enabled which i am sure it is not by default, etc
I do not think there is any way to disable it & you should not, cause then it may do a silent update when the time comes for a prompt..
