    Hello! I downloaded Windows 10 Tech Preview yesterday on my Lumia 1520 and its not working properly. Wants to revert back to previous settings (i.e 8.1). I downloaded Windows Phone Recovery Tool but it is not updating stating that one file/directory is corrupt. What to do to go backwards to Windows 8.1?

    Some possible fixes
    Uninstall and reinstall.
    Try LSRT.
    Check if your firewall or virus scanner causes this issue
    Try on another computer (at home or at a different place).

    Good luck.
