So, I did a rather stupid thing....Hope someone can help me with this?
I wanted to update the OpenWrt firmware on this router, and I chose the wrong firmware file.
I was supposed to use this firmware http://downloads.openwrt.org/releases/18.06.2/targets/ar71xx/mikrotik/openwrt-18.06.2-ar71xx-mikrotik-rb-nor-flash-16M-squashfs-sysupgrade.bin
but I made a mistake and selected this http://downloads.openwrt.org/releases/18.06.2/targets/ar71xx/mikrotik/openwrt-18.06.2-ar71xx-mikrotik-nand-large-squashfs-sysupgrade.bin
The router already had a previous version of OpenWrt on it, and was working.
I did the update through Luci.
Now there's no connectivity on the ports.
Is it bricked or is there way to recover it?
