ProgSkeet v1.1 - Crystal Blue Edition

Hi all, I need some helps(newbie here). My goal is downgrading my ps3 with ofw 3.70 to 3.55, then install cfw to play backup games. Im setting up the hardware, soldering ProgSkeet v1.1 - Crystal Blue Edition to ps3 board. I have the diagram from Progskeet website, but its the older version progskeet 1.0 (white board). So what i do with R7 (remove it and replace with switch?), and what about R9, R10, R11, R12? :questionmark:I know that R8 = remove.

I have:
ps3 CECH-3001A 160gb
ProgSkeet v1.1 - Crystal Blue Edition
30awg hook-up wire ok?
