I just found out that installing the cfw with peek and poke causes problems with ps1 games disc or bought games, ps2 games, and psn store bought games it casuses an error when starting them. it also casues ps3 activation error 80029519 the only fix is to do a quick format of your ps3 im trying a quick format on my ps3 and if i still get the error i'm going to go back to 3.55 ofw then do another quick format and see if that fixes.
Worked fine on my CECHG04 3.41-> 3.55 (through recovery menu) 3.55 kmeaw. You have to install the 3.55 versions of your backup manager and games with modified eboots will not work. If the game has an update you can find it in pkg form and it will replace the modified eboot and fix your game.
