So it's been a long, long time since I downgraded my PSP Classic to 2.71 SE-C. Now I want to "upgrade" it to the lastest custom firmware. What does everyone suggest is the best way to go about that. I've looked in the tutorials section and I see that there seems to be multiple methods now, including using a Pandora Battery or Pandora Memorystick or Despertar del Cementerio v7?
What do you guys and/or gals suggest as the easiest/safest route to take to upgrade my custom firmware from 2.71 SE-C to the most current one, which I assume is the 4.01 M33. Thanks for your advice and help in advance.
