    This is the "repaired" version:

    I received some of these "HW-628 V1.1" boards myself. They are not the same as the baord shown in your last picture.

    There are two mistakes on my HW-628 V1.1 board:
    -the pin label between SD0 and SD2 is incorrect, "GND", it should be labeled "CMD" (your board has the same problem)
    -the antenna is connected to the ground plane and does not work (your antenna does not have this problem).

    By making a few cuts in the ground plane I could restore the wire from the inductor (connected to ESP8266 pin 2) to the antenna and further to the ground via, and then WiFi works again.
