 Posted: Fri Aug 18, 2023 2:21 Post subject: Flash Serial Linksys e900 |
 |
Hola, este es mi primer post en el foro y la verdad es que necesito ayuda, hace un tiempo tenia un linksys e900 funcionando normal, necesitaba configurarlo como repetidor por lo que busqué en la web y me aparecia dd-wrt como solución, resulta que en esa instancia alfo falló en la actualización del firmware, no sé si fue el firmware incorrecto o un fallo con el proceso del reset 30/30/30, por lo que me di cuenta de que lo había brickeado y que necesitaria un usb-ttl para poder hacer el flasheo vía serial, hoy en día tengo el usb-ttl pero me surgen algunos problemas, intentaba flashear con la rom stock, primero tuve problemas con el ttftp y no se conectaba al servidor, supongo que será problemas con la configuración, vi muchos videos y aunque el prompt es CFE los comandos no son similares o no me funcionan, si alguien pudiese ayudarme, u orientarme, he leido casi todos los casos en el foro, adjuntaré algunas pantallazos de la consola
Esto es lo que muestra al encender el router
