(adsbygoogle = window.adsbygoogle || []).push({}); I have a updated ps3.
I want to do some hacks on it like emulators.

How do I do this this without downgrading my ps3?

You must login or register to view this content.

Theres the list of all the tutorials. Hope this helps.

You can't. And in order to downgrade you have to have infectus chip. Or one of the test PUPS.

What can an emulator do for your ps3?

Ye only the infectious chip can flash and download the nand . But it looks awfully messy to do.
