I recently bought a PSP from a buddy of mine and I have been for the last week trying to figure out the best way to mod it. The problem is I don't really want to purchase or create a pandora battery but I think I don't really need it either (right?). The question I have is what is the best route to go and how to get there?

From what I can tell is the first thing I should do is upgrade to OFW 6.20 (right?) because then I can go back to any version or go with 6.20 CFW (not sure which). Then I need to which Tutorial to follow. Any help would be greatly appreciated.

Thank You Very Much

P.S. If some of this is totally off I apologize.
