Hello, I have just received a mi4c and when i tryed to connect it to my pc it didnt go in mtp mode. I can only get in via ptp mode. After that i installed the image cd that keeps popping up while in mtp mode. But its still doesnt let me go in mtp mode. The computer is a windows 7 and it keeps saying driver not found and only shows the image of xiaomi cd that i already installed in chinees and english couple of times. Can some one explain me how to fix this.
