I've had this problem for a day or so now. I connect my lumia 920 to my PC (Windows 7 ultimate x64) the phone makes a connection sound and it shows up under My Computer. However when I go to browse the files on the 920 it is just empty. Also when I try and use the WindowsPhone app it boots up on the welcome screen as if it's the first time I'm connecting it and does nothing when I press the continue button...
This hasn't always been the case as I was able to browse the files and use the WindowsPhone app for over a week without trouble previously.
What I have tried so far:
>Restarting my phone.
>Reinstalling the WindowsPhone app.
>Repairing and reinstalling .NET 4.5 and updating it.
>Turning my firewall off
>Connecting it to another USB port.
>Connecting it to my other computer.
>Hard resting my phone. (This left me stuck on the cog wheels for hours and I had to flash my phone to fix this)
>And maybe more things that I can't remember at the moment.
Interestingly when I had to hard reset it and wipe everything off the phone it worked fine, the app let the phone sync my music etc, I thought it had been fixed. BUT the second time I went to sync my phone the same problem happened! WindowsPhone app thinks its the first time and wont let me press continue and the device is just empty under My Computer.
The phone works fine otherwise, all my music and stuff is on it from the first sync and I have 0 problems besides this! Any help would be appreciated and sorry for the huge post :/
I doubt it has anything to do with the phone. It's more likely something changed on your PC.
What you can do is connect the phone then go to device manager in Windows and remove the drivers by right clicking the phone in Device manager and selecting Uninstall.
Now remove and re-attach the phone to another USB port which should reinstall drivers.
Click on the Star Icon below if my advice has helped you or press the 'Accept As Solution' link if I solved your problem..
This is a slightly different problem than I am having, My phone is recognized and shows up as it is suppose to, it is just empty when I go to browse it.
I've also bought a new cable and tried it with completely different computers and the same problem happens on them. It has to be something to do with the phone.
SAME HERE ! is this problem fixed???
Connect the Phone to PC..Open Device Manager on the PC and Right Click on the Windows Phone under 'Portable Devices' .. Select 'Uninstall' ..and once it is done disconnect the phone and re-connect. Wait for the drivers to get re-installed . See if its fine now ..
Its not fixed yet.. i can't sync my files to my phone.. it says my phone is locked, but my phone is unlocked!
