Sony PSP with 2.6 Bios

[P00t]

So what can I do guys?

Is there a working downgrader that I can use without having GTA?

So many fakes out there, don't fancy bricking the PSP.

Anything I can do without downgrading if I can't?

There have been many success story in regards to downgrading 2.6, why not give it a go?

I've personally seen two PSPs downgraded successfully from 2.6. Mine was 2.5 before it was downgraded. From what I understand, the only risk of bricking your PSP comes from the power being cut while it is downgrading.
