I'm saying this because Nintendo completely rewrote the process9 code for the anti downgrade check. There's no reason to do this besides fixing a security flaw, and I'm not the only one who sees it this way. It's likely we'll have free software downgrading from 11.0 and 11.1 soon.
only ps5 updated to latest firmware can go on psn, jailbroken ones just don't use psn or they risk getting flagged or banned, altho spouting profanity in online play alredy does that
