My 360 has done this for the past few years now. What works for me is I take the front plate off and there are these two small holes right below the disk tray. I take the end of a paper clip (since it fits pretty much perfectly in) and if you poke around while pressing the button the tray usually opens. Sometimes it takes a while, but its always worked for me.
