Sorry for being rude, but it's just your paranoia
Go for what we have!
You beg us to don't say "upgrade your CFW", this applies vica-versa. I beg you, don't say you're still on 3.55. 3.55 people just gives more work for the scene. Anyway, you still can't use it. You need to upgrade to a higher CFW. (I'm on 4.30 rebug CFW, and if DLC doesn't work, I happily go to 4.46.1 REX rebug CFW)
