Alright, I was playing Uncharted 3 (goty edition) online, the game froze on the loading screen only after 1 hour of gameplay. I properly shut down the system...but the whole thing froze after that. I hold the power button to forcibly shut it down. While doing that, I stupidly pushed the eject button.
After turning it on, the PS3 doesn't read any disc (CD, DVD or BD). It makes the ejecting sound 5 seconds later after putting the disc in.
I always keep the PS3 clean and my discs are super clean.
I did the Restore File System thing but no luck.
Should I use the known lens cleaner?
Factory rest will help (aka delete everything)?
PS3 Slim 250GB. Got it in Jan 2010.
