Downgrading phat PS3 with Progskeet?

[NonaSuomi]

So I've made a few posts here before, I got myself a display model PS3 which is a CECHA series phat, meaning it's as old as they come. After suggestions here and a bit of my own research I have found that I'm going to need a Crystal Blue Progskeet v1.1 to get it done, since it was already up on 4.0 OFW when I got it, and I need to downgrade the FW to an earlier version. My problem is that I don't know how, and not having my finger on the pulse of the PS3 scene means I'm not sure who or what to trust, so I turn to you: could somebody please give me some guidance (tutorials would be great too) on how to install the chip on my system, and then how to use it, what can be done with it, etc? Thanks!
