Just dug out my old PSP. Trying to figure things out, but it seems that any support for us old timers is now just gone. How do I get myself up to 5.50 from 1.5? I'm on 3.10 OE-A right now, and can downgrade to 1.5.
Where do I go? I looked at the tutorials here.
But I'm confused about the "you need at least a PSP running firmware 3.52 M33-3". How do I get to there to begin with? There's nothing in the tutorial on how to do this. Any help is much appreciated.
