I've been searching for answers for a long time. I hope I get precise guides here! I have a 3.02 PSP. I'll get an unpatched copy of GTA: LCS soon. The first step is to upgrade to 3.03, then downgrade using noobz team downgrader, right? I'll then have a 1.5 PSP. Next step is upgrade to Dark_Alex's custom firmware. I wonder 3.03OE or 3.10OE? and how is that done? Third, I need to be able to play ISOs. What do I need to install and how? That's it. I'd appreciate your help and preferably direct links to guides/downloads. Thanks!
