I have windows 8.1 so maybe that's the reason. I just cannot for the life of me get this Microsoft computer to recognize the nexus 7. I have tried everything. Debugged both ways (MTP and P2P) and device manager is not showing Other Devices like the instructions tell you. Also, not showing Android ADB anything in the device manager. I have the drivers downloaded but cannot update a device that's not showing. Can anyone help here?
