My friend got used slim 120GB PS3.It worked fine a day then it started to recognized controller lately. Then only with USB cable. I thought it maybe SW releated. I tried to DG with toggle qa then tried to install 3.55 OFW then CFW but it never worked on anystep. I installed FW via FSM but it same too. I tried bluetooth headset it find but cant register although I input registering key correct. Then I though we never tried wifi but green light never lit cant find any network it gaves 80130128 error. I know now it caused by HW malfunction. So is there anyone fixed wifi BT board on PS3? Is there a way to fix it. I never tried to fixing coz may harm PS3 more.
