  1. mi teléfono esta sin señal (teléfono no conectado )
    puedo utilizar el mismo método? solo que en lugar dela actualización, seria un parche para ser root y poder modificar el imei,

    1. Hi Jeff,

      Get into the recovery mode and perform a factory reset. This should probably solve the problem and in case it doesn’t just flash stock firmware on your.
