Hello all,
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
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. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

You probably just fried your router. You do not use a serial RS-232 cable, the shifting voltage is 12v on a PC com port, not 3.3v; you need a USB-UART-TTL adapter cable. There is also the possibility that there are spots where there are missing components where the solder pads need to be bridged somehow or you have to manually short them to make connection. Also, you do *not* connect Vcc; TX, RX, GND only. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"
