In order to hack your psp, you'll need 2 items. First, a pandora battery and second a magic memory stick with all the neccessary files. As of right now, you're missing the magic memory stick. The pandora battery's function is that it will allow you to downgrade the firmware and the memory stick will then install the custom firmware, bringing it up to date. Both items are important in order to work. One item will not work without the other. You can create your own magic memory stick by taking a 1gb memory stick and down load the needed files. Ask any acid modder to assist you with making a magic memory stick and its files. Good luck....
