I've been trying to install CFW on my 3.55 demo ps3. i've heard of people stating that they have installed cfw on the same set up that i have. how ever i have tried to install every cfw available so far and can not from either the xmb or from maintenance mode. maintenance mode always tells me that my file is corrupt. xmb method won't find an update being as i'm already on 3.55. if anyone has any insight i'd love to hear it. thanks.
