Okay so I have this problem on my PS3 starting today. I turned it on today, and got greeted with a message that said "Your system cannot be run correctly" it tells me to insert my controller to the PS3 via USB, and then press the PS button. Then it told me that I needed to update it with firmware 4.11 or later, to make it work. I downloaded v4.20 and inserted it into my external USB following all the directions on the Sony website(like the folders and stuff), and then once I pressed "Start" and "select" at the same time it told me checking for update, and then there was a progress bar. After 100% nothing happened, and I restarted my PS3 and had the same message. I tried to do the update 3 times, until finally now when I try to do it, it doesn't even let me and says "Your system is in a serious error" or something like that. Help? PS3 is not under warranty. By the way my PS3 was never hacked, and it worked perfectly yesterday. I was on v4.11.
