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?
Hello @bss007, I was wondering if you managed to revive your router. Unfortunately I find myself in the same predicament; not even TFTP is working. Some information online leads me to conclude the bootloader may have been overwritten, so I'm wondering whether I should pay somebody to enable the serial port or buy a SOIC8 clip and flash the ROM.
Have you managed to find a solution? I flashed the wrong image and got a non funciotional device. USB led turns on for about two seconds and then turns off. Serial port is non functional. Not sure if soldering/unsoldering is needed. @Murchic and @root, could you be more specific? I got a SOIC8 clip and wrote a c20v1 flash dump (EU version) I got somewhere here on this forum. However, nothing changed.
I bought a SOIC8 clip and used my Raspberry PI to recover my router using, if I recall correctly, the instructions under Recovering from a bad flash / Unbrick your router: https://pwassi.privatedns.org/lede/archerc20i/.
I did the same procedure as you and the device still bricked
I've tried with the same "full dump" for c20v1(EU version) that you used and I tried with another dump generate by myself from another identical router that I have(a working device). The result was the same
If anyone has another tip to try, please tell us.
For now, I´ll put this on hold because this procedure writing the image directly was my last hope
