(adsbygoogle = window.adsbygoogle || []).push({}); I was on 4.21.1 cfw and was updating to rogero 2.03 but I forgot to take my mw3 disc out and my ps3 has gone to ofw 3.70 is there any way to get back to 3.55 or any cfw?

I did a little searching and the only way looks like downgrading via Progskeet or E3.

Ok thanks I think I'll have to sell it
