How do I install Dark Alex's 3.03b on my PSP? I currently have a 1.50 version PSP, running Devhook 0.46. I don't have any custom firmware installed. How do I easily get 3.03b working? Is there a chance of bricking my PSP? Do I really need 3.03b if I have Devhook 0.46? I would like to play PSX games, PSP ISOs, PSP CSOs. I'm not clued up with doing anything too complicated like messing with PRXs etc. Just need an easy guide. Can anyone help? Are there any pitfalls in installing 3.03b - eg. what won't I be able to do? Will I be able to revert back to my original 1.5 version if I need to?
