I am not sure if I used the right firmware in the first place, now no lights turn on in the router except when a lan/wan connection is present, and even then my computer does not detect the router gateway. Now its stuck and I can't even get it to recovery mode.
The same happened to me, make a tftp image using https://github.com/ashegoulding/tp-link_c20-v5.dev#how-to-make-tftp-images-w-mktftpimg and flash it using tftp
