My PS3 is in working condition: both downloaded and on-disc games work. However, ever since Borderlands 2 crashed on me once, it sometimes randomly crashes. I can reboot it no problem, it goes through a filesystem check in a couple minutes and then either everything works again (and I can play for hours with games without problems) or it crashes again and I have to repeat this -- but in general, after at most two cycles, it starts working.
Now, I've tried replacing the hard disk and restoring from a backup, but that doesn't seem to make the problem go away. However, I've found very promising mentions of a so-called "safe mode" of the PS3 which allows you to reset all kinds of internal databases.
My problem is that if I try to follow the instructions, nothing really happens. Keeping my finger on the 'on' button doesn't do anything, it just boots up the console in normal mode. I don't hear any extra beeps apart from the initial one as it turns on.
So how do I get into recovery mode on a fat PS3 running 4.53 if it otherwise boots into normal mode just OK?
