Hi,
where did you find these instructions?
I don’t think we have such factory reset other than re-flash.
For devices using SD cards as the booting media, we provide images that can be easily flashed into SD cards, which can be done on Windows, Mac, and Linux.
But for devices using other storage devices, this may be done only with SDK Manager or flashing scripts in our BSP, and one will need a Linux PC to do so.
