Exclamation LG L3 II E-425g Emergency Mode

I can't get the Emergency Mode in my phone (LG L3 II E-425g). I want to put another firmware but I can't because the kdz updater shows an error at the final of the process and I don't know why. I guess that it's because the phone isn't in emergency mode. Answers?

No puedo poner en Modo Emergencia mi LG L3 II E-425g. Quiero ponerle otro firmware pero no es posible ya que el kdz updater lanza un error al final y supongo que es porque el terminal no esta en modo emergencia.

Thanks
