Livebox 6+ Arcadyan ERV33AX349B-LT ¿Es posible el acceso root del router?

¡Hola a todos!

Necesito vuestra ayuda. Como muchos sabréis, el router Livebox 6+ de Orange creado por Arcadyan en concreto el modelo es el ERV33AX349B-LT es uno de los más limitados de la historia. Incluso los registros están capados, lo que es una violación de la privacidad del usuario. La empresa Orange, que distribuye el dispositivo, no me ha proporcionado ningún dato para acceder a mi dispositivo. He intentado todas las vías que he encontrado en línea, pero me faltan conocimientos para recuperar los registros de mi router y por eso acudo a los grandes hackers que tenemos aquí y espero que me ayudeis a recuperar lo que es mio y de privacidad...

He probado a soldar los pines UART en la placa para conectar el dispositivo a través de un USB-TTL y comprobando los voltajes para saber cual pin era el TX, RX Y GND finalmente conseguí ver en consola el puerto serial COMX, sin embargo, resultó ser el inicio de algún tipo memoria RAM o similar del sistema embebido, lo que me impide conseguir una shell por conexión serial y tira al traste esa vía o almenos esos pines por los que intenté acceder. Al final del post os pegare todo lo que consigo ver en el inicio del router a través de esta consola junto con los datos técnicos que he conseguido obtener del router.

Mis preguntas son, dadas las circunstancias, las siguientes:

¿Existe alguna manera más simple de conseguir los registros o el volcado de memoria?
¿Es posible conseguir una shell y entrar al sistema para recuperar los registros mediante la consola serial?
¿Es posible analizar las memorias sin extraerlas o crear algún tipo de puente que me permita entrar al sistema Linux que posee?
¿Cuáles pueden ser los puertos JTAG y las frecuencias que debo comprobar para conectarme al router mediante JTAG, y cuál es la diferencia entre JTAG y UART en términos de tipos de pines?
¿Pueden recomendarme algún software o herramienta para activar el acceso SSH o similar para poder conseguir mis registros?
¿Alguien conoce algún exploit infalible para la explotación local?
¿Teniendo USB 3.0 es posible crearle la shell a traves de este mediante código autoejecutable?

Agradezco cualquier ayuda que podáis proporcionar. ¡Gracias de antemano!
