He seguido los pasos para flashear el Z750i, que no encendía, solo vibraba. Ahora ya enciende pero sin importar cuales files emplee el resultado es el mismo: al encender el celular me pide un "Cod bloq teléfono:". le doy 0000, 1234 y no lo acepta, da Código incorrecto. Que estoy haciendo mal?
Agradeceré mucho su ayuda.
