Gracias por el tuto, muy "explicito" jejejeje. Tengo un problema, estoy liberando un k790 y tengo 2 chips, uno de prepago (el cual ya solo me sirve para hacer pruebas) y el otro postpago. En uno, porque no le he puesto saldo y ya se perdió la linea, sale SIM Inactiva (bueno, eso lo deduzco), y con el otro Solo Emergencias. Cuando entré en el menú oculto <**< con el chip 1 salíeron los 2 candados abiertos, y luego, con el chip 2 ya salía el de red cerrado. Pego el log del proceso y otro de un Identify que le hice cuando había probado ya los 2 chips.
