There are different ways to update MIUI OS. You can download the patch/ROM and apply it manually but the easiest way is to use the Updater application. Most of the time, the OS looks for updates and throws a notification when there is an update. We have compiled a few guides for Xiaomi Redmi Note 4. Head to this page to see the full list of guides. Also, do not miss our “Recommended Smartphones” list that contains best smartphones for every budget.
Open Updater application.
Click on ‘Check for updates’. If there is an update available, you will be prompted to download and apply. If you have downloaded a patch/update without using Updater, have to place that in downloaded_rom’ and then click on ‘check for update’.
Another option is to click on ‘hamburger menu’ on top right corner, click on ‘choose update package’.
Now, select the patch file that you want to apply and click on ‘ok’.
If you want to disable automatic updates or if you want to disable checking for updates when connected to mobile data, click on settings from ham menu. You can also reboot into recovery mode from the settings menu.
