Progskeet PS3 questions help?

[v1p]

Hello, I am wondering if the progskeet can downgrade my firmware 4.23 (store) which is a demonstration model CECH01.. I know so far its a nand, if so where are the diagrams to solder or better method of installing, i'm look at Progskeet V1.1 Crystal Blue Limited Edition and a solderless clip... just want to know all i need and like i said a diagram for nand.. thanks in advance

forgot to mention that date it was manufactured november 2008.. so i think its good.

the Progskeet v1.1 is still a problem for PS3 FW. 4.23 downgrade, but you can try it for Progskeet v1.2.
