hope you guys could help me out on unbricking TP Link Archer C20 v1
I installed OpenWRT from https://openwrt.org/toh/tp-link/tp-link_archer_c20_v1, however something went wrong.
Currently when i turn it on - only USB LED lights up and nothing else, USB LED shines for a couple of seconds and turns off.
So i bought CP2102 chip to connect to the router via serial, however was not receiving anything in Putty console - decided to check the voltages on the TX and RX pins and they are both 0. Do i need to do any additional steps to be able to connect to the router via serial?
