Ayuda Brick RT-AC68U

#1
Buenas.
Si algún alma caritativa me pudiera echar una mano se lo agradecería muchísimo.

Tras estar funcionando perfectamente con Merlín se me ocurrió la desafortunada idea de instalarle LEDE y ya no arrancó mas. Después de mucho buscar no consigo encontrar nada para recuperar el router.

Se queda con el led de power encendido fijo y la WAN parpadea si se le conecta un puerto ethernet pero no funciona en ninguna dirección de las que he probado (192.168.1.1 192.168.0.1).

No puedo acceder al cfe miniweb server ni dejando apretado el reset ni el WPS.
¿Alguna idea?
Saludos

tienes que hacer un reset de fabrica con el metodo 30+30+30, buscalo asi, reset asus 30+30+30, borras la nvram y te bajas el ultimo firmware y lo instalas.

Lo he intentado varias veces con el boton de reset pero no pasa a modo rescate( led power parpadeando). Tampoco va con el de WPS.

Buscando por internet he visto comentarios de que se pueden recuperar conectándose por el puerto serie, pero no me queda claro el tema.
Parece que tendría que comprar un interfaz USB-TTL para poder conectarme directamente por el bus serie.
Lo que no tengo muy claro es el procedimiento. El ingles no es mi fuerte y avanzo muy despacio.

Hola que tal , yo tengo este https://www.amazon.es/Cable-Conversor-Serie-SERIAL-PL2303TA/dp/B072LH1K4Q y con algunos cablemodem me ha ido bien , el router lo tienes medio muerto , casi seguro el boot te lo has cargado por eso no arranca , desconozco el procedimiento para cargar toda la flash por puerto serie ,e usado el busybox y por ahi si podrias hacer algo pero el router tiene que arrancar . Yo uso un programador usb jtag nt para programar cablemodem puma 5 que llevan un chip de 16 pines muy facil de programar con un test clip sin soldar . El cable es barato compralo e intenta recuperarlo enredando es como se aprende , un saludo

Hola
Ya he conseguido conectarme al router por el puerto seriepero lo unico que consiguo es el volcado del CFE.
Por mas que intento el ctrl-c no funciona.
Alguna idea.
