Hi @Leemallin. As your phone is from a different region, the only way you'd be able to receive updates through the conventional method (i.e. Settings > Software update > Download and install) is if your phone is connected to a network in Nigeria.
However, it is possible to download phone updates manually by using our Smart Switch service. To do this, you will need to download this service onto a computer. You can find the relevant links for doing this by clicking here and selecting the section titled "Download now".
Once you have downloaded Smart Switch to a computer, please follow the steps below:
> Connect your phone to your computer using a USB cable, and then open Smart Switch on your computer.
> If a software update is available, Smart Switch will automatically prompt you to download this.
> Click "Update", and use the on-screen prompts to download the necessary files.
> Click "OK" to proceed. Your phone may turn off and on a few times during the update process.
