Wrap Up
If you are in Stock firmware, Use a Simple method. It is comfortable and safe; You can update like a Regular OTA Update. But if you were already using Custom OS or Rooted devices, You can try TWRP Method. If you moved to another region, and can’t get the update, You can try VPN and change it to your Purchased Region and try to get the update in settings. Most of the time, this method will work. There are plenty of free VPNs for Android are available. Don’t download any third-party apps; sometimes, it may trigger the updates process. In my opinion, Color OS is better to compare with some other Custom Skin OS like MIUI. So try to use this OS instead of a Custom OS. But the decision is your choice…:)
