To be honest with you Ive never seen a psp say "you must activate the system to play"....
Anyway, to play homebrew, isos, etc youre going to have to downgrade your psp to a 1.5 and then upgrade to the custom 3.03 firmware.
To do this you will first have to upgrade to the regular "official" 3.03 firmware since you have a 3.02 right now. After that you will need to download the downgrader and have a copy of GTA:LCS to get the downgrader to run. The game has to be the original unpatched version. After that youre golden. If you dont have GTA then youll either have to buy it or wait until another exploit is found so you can downgrade.
Sorry My psp says to use this content you must activate the system, please I know nothing abvout these things.
