I too had this… Froze at around 30% on an update once. I tried a few times, update downloaded perfectly fine, just wouldn’t apply. I reformatted the HDD, no change, tried a USB memory stick by downloading the update on my PC, nothing worked.
Sony swapped my PS3 out for a new one, or at least this is what I was told. It wasn’t new, it was a refurb unit.
6 months after, refurb unit died. Blu Ray player wouldn’t read any discs. Sony swapped it again, about 4 months after that the replacement developed a fault where all I got was a yellow light… Sony charged me this time, £90 I think to get a 40GB PS3 replaced..
To be honest, after that I kind of lost interest in the console, and sometimes resort to calling the thing the most un-reliable Gorge Forman grill I’ve ever owned. I haven’t even turned my PS3 on in nearly 6 months now…
After the Playstation and Playstion 2, I have to say the Playstation 3 really has ruined the brand for me... I used to rate Sony and its consoles really high... not any more.
