delete update and re install it if not work i am sorry but delete your all files about mgs4 saves

That makes sense... 

Seeing as after the update you lose that data anyway.

i have a ps3 150 g and does not read my MGS4 as well, I dont know what happened

My bluray drive went out and I replaced it. Single layer games played fine but MGS4 would not play and if I recall correctly it would show a symbol of a disc with a question mark on it. The people I bought my replacement drive from sent me another and that fixed the problem. It may be that your drive just wont play dual layer discs.
