3.11
Would be best to play with. Since most people are on it
Also their a 3.15 update now.
But ps3 all the keys was the same up to 3.55
Ps3 I'm sure all key are the same. After 1.76 or whatever since that Linux exploits.
So if you had the keys for 3.11 you would have keys for all FW I'd hope.
Go big start on the new it's
Fw
"3.15"
