I think making a downgrader is easy but I suck at lua coding but learning it step by step so I think if you get the 5.03 flash 0 and 1 files and have the program detect psp 3000, 2000, 1000 (and psp go) then we can have it flash install the 5.03 files for the psp 3000 through the hbl exploit.
It seems fairly easy to say but much harder to work with...
I'll see if my buddy -Val- (a lua coding geek) will help me into the thought and process for this downgrader.
I was thinking the same but, isn't there other things involved? I mean, if it was that easy, there would be a 5.03 for 5.50, 6.10 or even 6.20 already. Anyway, if you need a hack'd PSP, I'm here to help (decrypting stuff, I mean).

Good idea but I'm pretty sure downgrading requires kernel access, and if you have that then why downgrade?
