    What is the exact damage done to the board? I am not sure that I
    understood what is fixing your method. Initially I thought that you
    had an overvoltage and damaged the micro and the only way is to replace
    it :)

    The clone arduino uno (R3) does not work when you set the Arduino IDE board as Arduino Uno. This is the correct board.
