I tried to upgrade my TL-WR941NDv5.1 and bricked, now I tried to find serial connection but could not success, I haven't seen as my board. can any one help me recover my router back. LAN port 4 keeps blinking on startup and not working. I attached board Picture.
And the v6 is "Atheros", Qualcomm is Atheros. Also, if you look at the yellow of the LAN ports housing, it says v5.1
yes exactly v5.1
JP1 is the serial header, pins need to be installed or you need to figure out how to jam the wires in the holes to make connection. That setup looks similar to the v6 serial header picture on the OpenWRT TOH.
but I can't find the same with my device's board to understand how connection will be.
