(adsbygoogle = window.adsbygoogle || []).push({}); I just started using my old ps3 again, yeah its been a while :p . I just wanted to know if it was possible to downgrade 3.60 to 3.55 WITHOUT AN E3 FLASHER so I can upgrade the hard drive from an 80gb to a 320gb. Thanks in advance!

Anything after 3.56 needs E3/Proskeet.

So if is 3.56 what i can do without E3/Proskeet?
