If you are in Stock firmware, Use the Internal memory or Stock recovery-based method. It is comfortable and safe; You can update it like a Regular OTA Update. But if you were already using Rooted devices, You can try TWRP based method. Don’t download any third-party apps; sometimes, it may trigger the updates process. There are a lot of new Gestures available in this update; try them also. In my opinion, When you hate MIUI, You can try to root your Xiaomi Redmi K40 and install custom ROMs. They are better compared with some other Custom Skin OS. But the new MIUI is better. So try to use this OS instead of a Custom OS. But the decision is your choice…:)
