You are bricked...and I am not sure if there is a way to recover it. RealTek processors are NOT supported by dd-wrt.

looks like your baud rate is wrong....try 115200 8-1-n.

try all the various baud rates....not being a compatible device...you will have to try them all until you find the one that is correct.

What are you using for a cable? Try reversing rx and tx. RX of your cable sometimes needs to be connected to tx of your router and vice versa. (Router is txing and cable is rxing)

You router does need to be plugged in. You might need vcc+ on that cable. Read the serial wiki. Make sure you have a proper level shifting ttl usb cable.
