We recently purchased a PSP 3000 that is running on firmware 6.31. I've been following the guide and it seems that I need to either be on 6.20 or 6.60 to be able to hack the PSP. Do I downgrade to 6.20 or do I upgrade to 6.60 before doing anything? Sorry if it's a stupid question, I'm very new to this and can't seem to get myself on the right path. If you would help me out I would be very grateful.
