I am sorry to ask you this, I don't know where else to ask this because no one else know about this serial things but openwrt community. So I got mr50g, it's bricked, I tried recover it via web recovery. It seems to accept and write it to it's flash, but not really. It goes back to web recovery.

The image is like this, green is TX, white is RX, not sure which is GND(black one). Most likely it's the hole near the green. Not sure though.
