ok I got a PS3 with three blinking red light error and I had read that its pretty much the same as RROD so I took it apart and did a heatgun reflow and put it back together, but it won't pick up the signal from my wireless controller. I took it apart and I didn't see any connections not put back together. So what did I do wrong?

Did you connect the Wireless board correctly? See the pic following. Also be sure you plugged the wire of the small daughter board, properly.
