2.4" TFT LCD Shield isn't working on Arduino Mega

Even on ebay's website it is mentioned that I can't use 2.4" TFT LCD Shield display on attach to Arduino Mega. The problem is that I bought this shield by mistake. I want to put this shield onto Arduino Mega 2560. Is there a way to combine Mega and 2.4" Display Shield?

note: I tried on my friend's Arduino Uno. Shield is working very good.

note: The photo below is determining my question. The display not runs my Arduino's code. It only runs its LED.
