that part of the wiki page was a reference for the devs.
the progskeet was being developed and they needed to see what it could do and couldn't.
it was posted incomplete but it is useful.
the 1.00 f/w was never extracted fully. but the ps3 can be downgraded (not from 1.00 though )
if you have one on 1.00f/w and you can extract a dump then post it over there i am sure the devs will appreciate being able to look at a full dump
