Thanks to everyone who cntributed to the success of this post. Great thanks to eryen, mexus and ah_es_2000 for their continuous support.
CUIDADO! Uno de los pasos es formatear todo, con lo que se pierde el IMEI, para eso hacemos el backup de la nvram. Este metodo es bastante peligroso, usar bajo propio riesgo!
