Overflow flash in 2.71

[PSPHax0r9]

Wait, if we found a way to run homebrew on 2.7+, wouldn't we have a downgrader, since the overflow bug that allowed us to downgrade a 2.6 is still in 2.7+?

Hmm...maybe you're right. But first we need an exploit that can run homebrew.

[Realn0whereman]

do we know the 2.7 syscalls?

[Steverocks]

i dont think so.

Hmm, I wish I knew spanish, then I'd know what the thread starter was saying, Im gonna try this right now! It's not none of that edited LocoRoco crap, so I beleive this may come to an eLoader eventually!

Just read the last few pages and you'll find some crude google translations. Google sucks at that. Pretty much all services do.

Right, A chess game causes an overflow.. Yeah. :Argh:

You guys that are saying this will be an exploit are stupid.

All it did was crash. There are lots of ways of crashing a psp but non are exploitable including this one.

[metanoli]

overflow's based in a game of chess. I'm work in this, because the game I erase the flash1 of my PSP. I'm interesting in this work, because I think that it can have something



My english is sad XP

[TeamOverload]

Doesnt seem to be exploitable. Not surprisingly...

[jen_1982]

I have to agree this won't open an exploit.

It's a Chess Game with a tons of the code missing due to this the PSP crashes and shuts down. I think it is save to say that this is another speculation that can be rejected.

I'm Spanish, I can't speak in english

1- Copiar la carpeta rar en la raíz de psp
2- Abrir el navegador y poner "file:/index.html"
3- Se os abrira una página, picar a START, y la PSP se colgará

it isn't fake.

Yo te puedo ayudar con eso si quieres amigo.


I think that this cant be xploitable
