Hey guys. I haven't touched my PS3 in ages, pretty much after I installed the kmeaw 3.55 CFW last year. I found a cheap copy of Uncharted 3 the other day and decided to pick it up. But when I popped it into the console, it wouldn't let me play it until I upgraded to 3.7+. Is there a way to play the disc without upgrading my CFW? Thanks in advance!
