Problems Getting MTP Working
I've had the Nexus 7 2013 for a few weeks now and I'd like to root it. I have the Nexus Root Toolkit NRT v1.8.3, and want to do the Backup procedure before rooting. But it won't reboot my device. So I clicked the "Full Driver Installtion Guide" button and can't get beyond Step 2, Configuring MTP Drivers.
Coincidentally, I can mount the device on my PC in PTP mode, but not MTP, which is more useful to me anyway.
My PC is running Windows 8.1 Pro Update 1.
