What is not working? This code might successfully modify the pixels you downloaded from the graphics card, but it won't upload them back (unless you did it later in your code?)

so if you could me tell how can i upload my received pixel back?

If your sprite has initially a StreamTexture on it, you will have to create another one of type ImageTexture.

var tex = new ImageTexture()
tex.CreateFromImage(image, map.GetTexture().Flags)

Note: in your code you are filling the whole texture with the same color, you could use Fill instead.
