I think that remove the microphone, speakers and cameras are unnecessary. I had change the digiter and don't remove anything just the screws and be careful with the speaker and unlock the digiter cable in the left upper side and that's the parts that I had removed then the parts that you need remove is the battery and the 3 screws and unlock all the cables and the parts attached to the screen and that's it....
