I currently have a 2.60 version PSP, and I have received/downloaded most of the EBOOT updates with all the necessary update versions. I am planning to get the PSP Slim, so I am thinking of downgrading my 2.60 PSP Phat (after buying the PSP slim coming in September, with the new features), since the phat PSP will no longer be any use of me. So, now I am wondering...... What is the best downgrade method to get back my 1.50 firmware? Should I upgrade to another PSP version, then use some downgrade method? Guess what I'm asking is, what's the best, easiest, and/or latest downgrade method?
BTW, I refuse to use any downgrade method in which I have to buy another game (like GTA Liberty Stories) just to do this. :Argh:
