I'm trying to connect my Note 2 to my Windows 7 computer via usb but can't get it to connect. This used to work for me but since one of the recent updates, it will no longer work. When I plug it in, it says connected as installer on my phone. I click that, go to the MTP and PTP options, hit MTP and nothing. As soon as the box is checked, it unchecks itself. I've tried this multiple times, booting the phone and computer and installing the drivers from the phone. Im trying to access files on the phone, so I cannot simply remove the SD card and use a reader. How can I get this to work?
