    I had this problem but cannot be solved by following your method.
    After searching the web for an answer finally I managed to solve the problem.
    First close iTune and disconnect your idevice.
    Then go to start and type in %ProgramData%
    Go to the Apple folder and then go to the Lockdown folder.
    Delete all the files in the Lockdown folder except the system configuration file.
    Restart iTune and connect your idevice .
    Your should be able to back up your idevice.
    Let me know if this work for you.
