At least in Europe the updates comes in weird manner. Guy next to me can get it but not me. When asked Huawei they said they release updates in stages. Whatever that even means.
Research dload method to update your firmware manually. Make sure you know what Cust codes are before doing this however, as if you mix different Cust codes to what your device is ,it'll soft brick your phone.
