So I pulled out my psp from years back for my kid to play with but I'm on 2.71 se-c and need to update it to make some new games work. I've tried recovering to 1.5 using recovery but I can't get it to run/return to 1.5. I've read that it might work with the 2.0 eboot but can't find that online. Does anybody have any ideas on how to update this to the latest firmware?
