So I got a PSP Go (which I'm enjoying) and now I've decided that I have no real need for my 3000. As such I've decided to sell it, but I'm wondering what I should do to prepare it for sale. It's currently at 6.35 pro and I'm thinking I should try and return it to a non pro form, so the next person to own it won't freak out that it's been hacked. That seems unlikely but you never know, some people are squeamish about that sort of thing. I could just upgrade to the latest firmware and I assume that would totally undo any hacks, but for some reason I'd rather not do that. Just in case the next owner is PSP savvy and wants to hack it, I'd rather they have the opportunity to do so.

So my question is: is there anyway to take my PSP back to plain old 6.35? A legit firmware that would pass inspection to those unfamiliar with hacking, but still low enough so that a potential hacker could still pull it off?

If anyone has any thoughts on what I should do here, I'd great appreciate hearing them.
