I just bought a Sata-II 60 GB HDD in the hope I would be able to 'reset' my PS3 in a way so that the 3.55 FW which is currently on it would be gone...but sadly I forgot that the FW isn't kept on the HDD...
So I'm gonna have a shot at this

I'm downloading PS3HDD studio and already have a USB transfer cable for the HDD...
I'll tell ya how this works out >.>
