How to flash OpenWRT router

Have a look at this screenshot. It’s my experience when installed OpenWRT system image via command line. I did that way because it’s almost broken and I thought it bricked. But fortunately, it could be connected via SSH, and I reflashed the image with mtd command, after I scp-ed the binary image.
