You may want to Revisit the PS3DevWiki my friend, The Menu is pretty much the same, lvl2 Has most of the keys but is not for PKG's It is mainly to get ISO's running or to get homebrew that needs lvl1-2 Calls working (Such as otherOS or something that dumps stuff) We would need to Exploit lvl0 to get CFW working properly on 3.6x+ Because the change in Boot Order We could also Exploit Bootldr To get All the keys
