Hi there.
I recently updated my Nokia Lumia 920 to the Black Update - before this it was fine and most things worked okay.
But now I cannot connect it via USB to my PC which is running Windows 8.1 - it charges and has recognized it once which it said the device had malfunctioned previously - but now it won't even show up with that. There's nothing under Devices and Printers and also nothing under Device Manager.
It is the Nokia USB cable that came with it and also I have tried plugging it in and doing a soft reset - still no joy.
Uninstalled all Nokia related content from my PC to try and start afresh but nothing. The phone itself is working but recently it won't let me upload images to Facebook and also the Facebook app is being weird and won't connect - not sure these are linked but thought I'd mention anyway.
Has anyone got any suggestions at all because it's doing my head in a bit now and I have tried most of the suggestions that I have found through searching this site and others.
Thank you.
