+Rotate the cover counterclockwise to remove the cover. Unscrew the 220VAC L and N Wires. Remove three screws on the transparent diffusor.
+Now the PCB is completely exposed and unmounted from the base. 
+3.3V, GND, TXD, RXD and IO0 Pads are clearly visible on the main PCB near ESP32 board.
+To flash ESP32 you need to solder the wires onto that test points.
