I have a PS3 with 3.55 Kmeaw installed. I want to upgrade to the latest cfw. I really haven't used my PS3 much but think it's time to upgrade. The guide I followed to softmod didn't have me make a NAND backup, so I probably want to do that but I looked in multiMAN and cannot find the option to make a NAND backup. And, I'm thinking there is something else I should have done but cannot remember what it is called, it has to do with being able to downgrade cfw without bricking, if that's even an issue anymore I don't know. What I want to do is just reinstall the 3.55 ofw and then install the newest cfw, is this the correct way to do it?
