(adsbygoogle = window.adsbygoogle || []).push({}); Hey guys, is it possible to download 3.55 files onto a USB, then update via media storage on PS3? Will that jailbreak it to 3.55?

If you mean from OFW 4.31 to CFW 3.55 then no. Downgrading on OFW >3.55 requires a hardware flasher such as E3.

Sweet thanks for the help. Are they those little dongle things that you can buy for like $25? By the way, can you online if it's jailbroken? Some say yes, some say no. What's the deal?
