(adsbygoogle = window.adsbygoogle || []).push({}); the usb thingy if i was to buy that would i be able to go back to 3.55 im on 3.56 ? just a question dont flame me O_o

Nope the things on the usb are not signed for 3.56 but if your still on 3.55 then yes it will work

Nope, would not work for 3.56 If your talking about a normal USB... And a firmloader wouldn't work because Sony removed boot code (required for Linux enablement) with the 3.42 OFW!! Plus you posted in the questions section So no need to flame lol :p
