Just want to let you know guys that the project was not a succesful one. I formatted the system, I upgraded the firmware also. But still the Wifi is not working. I'll try to open the system again and see what's really wrong about it. I probably missed something or I need other parts or maybe the WiFi that I Installed is'nt working at all. But for now the WiFi upgrade project will be put on hold. I need to find someone who's selling PS3 parts and it's a pain in the ass because nobody's selling any dismanted PS3 anywhere.
