PSP V2.0 to v1.5 Downgrade guide

[Ellises]

I found one USA game that has the 1.5 update on it, Death Jr.

[Accordion]

it should be a usa update on it then, use that to downgrade.
i think that certain games are pressed before the final specs for that region psp are released so an update may appear that shouldn't really

yes you can use a mac to downgrade a psp, all you do is transfer the files over, no programs are used, easiest way is to use PSPSetX through the eboot loader and then run a 1.5 update

[grin.ch]

worked like a champ all 3 times I used it!

THIS WORKS FOR ALL PSP'S Downgrader download at bottom of post.

When you say "ALL", do you mean a 2.60?
'Cause, the overflow thing isn't working

[Cooe14]

He means "ALL" as in all regions i.e.-1001,1002. He does not mean firmwares.
THIS ONLY WORKS FOR 2.00 NOTHING ELSE.

[Rokka]

So there is nothing i can do if i have 2.7?

[Cooe14]

With 2.7 your completly screwed. There is NO way to run homebrew like there was with 2.6 and the GTA exploit, and there is NO downgrader.

I'm currently downgrading my psp, I just started this whole "hacking" scene last night around midnight. It actually was kind of like a kid saying "you can't put sonic on a psp" because he had a palm pilot and thinks it's just awesome where as the psp is 1000x greater than a palm pilot. Anyway I'm at about the last step, just waiting for my psp to reset automatically I installed v1.5 but it still hasn't reset, might just do a hard reset because it's been sitting here like this for ohhhhhhhhh 4 minutes now. But yeah, I'm excited finally I can play other stuff besides Quake, and I shouldn't need gta anymore if I'm thinking correctly which means, I can trade that in, and another psp game and a movie, and get a 1gig (i'm on the 32 still) and just use for emulaters and stuff, that should be enough room for homebrew stuff right? Anyway, I love the site or site that linked me to here, but yeah. Thanks again for the help with downgrading, it went very nice.
