Soldering a proximity sensor back onto a flex is certainly possible. Ideally you need a hot air station and some practice (or experience). Use a lower temperature setting so you do not melt the plastic "box" of the sensor. However, looking at your picture, I fear that the metal pads (that are normally) on the bottom of the sensor are still on the flex itself. If that's the case, then there isn't much you can do other than order a new FCAM/Sensor flex.
