CFW update

I'm using a psp 3000 with http://pspslimhacks.com/custom-firmware-enabler-3-50-released/ this and I'm tyring to play Gods Eater Burst and it keeps telling me the game won't run. I'm thinking I need to update but I don't know how.

update your psp to firmware 6.60 either through the update function on the psp or from http://us.playstation.com/support/systemupdates/psp/pc/index.htm and then download the latest pro cfw from http://code.google.com/p/procfw/
