Cuando se reinicia nunca entra en el sistema operativo. Así que me toca wipear y reiniciar. No se rootea y no creo hacer algo mal. Activo depuración, orígenes desconocidos y 10 mins de espera en pantalla. Gracias por leer esto.

P.D:

Con la 1.1.7 si se me rootea, con la 1.1.8 no. Y claro, si rooteo con la 1.1.7 y después actualizo, pierdo el root.
