I had some trouble trying to flash this device. After a lot of tinkering and resoldering I finally got it to work by also connecting RST to 3V3 and skip the cross connect on RX/TX. I used a CH340G USB-Serial adapter when flashing.

Board    USB Adapter
3V3 ---- 3V3
GND ---- GND
RX ----- RX *
TX ----- TX *
RES ---- 3V3

* No cross connection!

These sources were very helpful when trying to figure out how to open, solder and flash these smart plugs:

I flashed like any other device. I connected GND-GND, VCC-VCC, TX-RX, RX-TX. I then pressed the button and then released, while turning on to enter the flash mode.
