    Probably the contact between your phone and your PC is not perfect.
    Try to use a different USB cable or a different USB ports.

    With the Lumia recovery tool, choose my phone won't turn turn on then plug in the USB cable. If the firmware is already on the pc and the phone is switched on, it will be set to flash mode before downgrading begins.

    Even though it shows the Technical Preview, if you go ahead with it, you'll have Windows Phone 8.1 after it is done.

    I can verify this, since I downgraded my device from an earlier TP build to 8.1 on Friday, prior to installing TP 1036 build.
