I believe this is a simple enough question, with just as simple an answer. I think I already know how, but I want to double check, because obviously I don't want to brick my console. I jailbroke using PS3Xploits (so I don't have or need an E3 Flasher) and am running 4.81 Rebug (if it makes a difference) My guess: You downgrade to 3.55 and then just do a normal system update via internet? I want to unjailbreak my console to safely play Destiny. I miss the game, and don't want to risk the ban, simple as that.
