Flash OpenWRT from OpenWRT (!)

Copy the firmware in router's /tmp. Why /tmp? Your router has more volatile storage than persistent one, moreover you will overwrite the persistent storage. So, copy the firmware in /tmp! Next, we will use the sysupgrade command. -v is verbose, -n ask openwrt to erase configuration files (ie. ask for a factory reset).

sysupgrade -v -n /tmp/openwrt-ipq40xx-generic-compex_wpj428-squashfs-sysupgrade.bin
