One need only look at the XP SP3 fiasco involving Symantec for a good example.
Reports have surfaced at the Playstation forums of issues while downloading the firmware, console freezes, and reboot issues. One user, noting the number of issues posted on the forum, decided to post the tongue-in-cheek thread, "Is there anyone who downloaded 2.40 update and had no problems?"
Naturally, there are plenty. There are also, it appears, plenty who did have problems. The first post on the thread reporting issues said:
Well, I downloaded version 2.40 put in metal gear solid 4 and i get a black screen forever..i cant even get demos to start..I got my Ps3 on Launch day..So my warrenty is out now..Any advice? I can take a vid if anyone wants.
Not necessary as someone confirmed the report. No word from Sony yet.
