if you could, get a sharp object such as a knife, and ever so carefully try to go around the edges of the button to get any gunk out then if you take of the beck you will see 2 screws at the top and 2 on the bottom they should be at the corners, unscrew and you should have access to the power button from the inside you will then notice that you can scrape anything off. Well, that fixed my phone im not so shure that it will work for yours. thanks, Jessica
