Flashing using only a USB to serial converter will not work as the unit draws too much current as can be observed by a flashing blue led on the PCA and a lot of serial gibberish. As AC is not connected to Gnd I used the available power supply of the unit and connecting the USB to serial converter to J3 pins Gnd, Tx and Rx.

The button is not connected to GPIO00 so flashing the unit requires some extra work. I managed to flash the iFan02 by soldering a wire to TP16 (GPIO00) on the bottom of the PCA. While connecting this wire to Gnd and also keeping the button pressed when applying power to the unit will be in firmware upgrade mode.
