I've been away for a while and need some help. I have a molded ps3 system on Rogero 4.55 fw. I haven't used my system in close to a year. I wanted to see Capt America civil war in 3D. I got a copy and found out that I can't play it cause the firmware isn't up to date. If I update the firmware will I be able to watch blu rays as well as play the games I have on the hard drive. I have an older fat ps3 model machine If doing so can fix my problem, which of the newest version of firmwares should I use.
