mangOH Red Getting Started failed in checking modem mode


#1

I am new to IoT and I am trying to set up my mangOH red with WP7702. I’m following the getting started guide:
http://mangoh.io/uploaded-documents/Reference/mangOH%20Red/Discover/Getting%20Started/mangOH%20Red%20GSG%20-%20Windows%20R2/#t=41112261_mangOH_Red_GSG_-_HTML5%2F41112261_PrepMangoh%2F41112261_PrepMangoh.htm%23TOC_5_2_Build_Install_mangOHbc-2&rhtocid=_4_1

Everything has gone as the guide says. The board is connected via USB cable. When I try to flash the generic firmware from the Sierra website I get the following error:

Firmware download failed.
Primary error code: 82 - Failed in checking modem mode.
Secondary error code: 0 - Not applicable.
Device error code: 0x0 - Unknown device error code.
