I have an RB711 5HN
To be updating the firmware, there was a power outage.
Now the RB will not start.
Can anyone tell me to do to recover it.
Thank you all.

Tengo un RB711 5hn
Al estar actualizando el firmware, se produjo un corte de luz.
Ahora el RB no arranca.
Alguien puede decirme que hacer para recuperarlo.
Gracias a todos.

according to manual:

S301 – Holding this button during boot time will make RB711 look for Netinstall servers. Release the button after
the LED light goes out
