My problem is that when I connect my N4 via USB the phone says "Connected as a media device" but it fails to appear as a drive that I can explore in 'my computer'. It also fails to appear in device manager so I cannot update drivers using that method.
I managed to upgrade to JR9 by transferring it via Bluetooth (took a while), this installed fine.
I also have a Galaxy Note 10.1 tablet. This appears without any problem. So why doesn't the Nexus? The last Nexus did.
I've tried connecting in USB debugging or MTP modes, neither works.
My PC is Win 8 pro 64bit. I've tried using USB 2 and 3 connections and alternative USB leads.
As I said, the phone sees the PC, it charges and says it's connected but the pc doesn't see it.
'ADB Device' sees the Galaxy Note but not the Nexus.
I've tried everything I can think of without the Note connected in case it was interfering, but to no avail.
And I've done some Googling, it seems there are other people with invisible Nexus', lots of suggestions, but none that work.
But with the knowledge in here, I'm hopeful.
Any ideas / suggestions would be greatly appreciated.
