Many Xiaomi and Redmi smartphone users face a situation where automatic MIUI upgrades bring more problems than benefits, the device starts to run slower, battery power goes out or critical interface errors occur, and at such moments there is an urgent need to return the previous, more stable version of the operating system.
The rollback process is not always obvious, as the manufacturer does not provide one Cancel Update button in the standard menu, but there are proven methods to clear the bootloader cache, delete installation packages and even reflash the device to an earlier version. It is important to understand that each action requires care to avoid losing personal data.
In this guide, we will look at all the available solutions, from simple data cleaning of the system application to complete flashing through the computer, you will learn how to prevent the automatic installation of unwanted software and the risks associated with the forced downgrade of the Android version.
Why you should roll back the MIUI version
Often new firmware versions contain bugs that developers didn’t detect during the testing phase, and users are the first to notice that system optimization has deteriorated and background processes have begun to consume more resources, in which case going back to the previous build is the only reasonable solution for comfortable use of the gadget.
Another reason may be loss of functionality: sometimes newer versions of MIUI remove useful features or change the interface logic to which the user is already accustomed, for example, changing the notification system or removing the ability to adjust the lock screen can become critical.
⚠️ Warning: Before any manipulation of system files, be sure to back up important data. System rollback can result in complete removal of information from the internal drive.
App compatibility is also worth considering. Some programs may not work properly on the new version of Android that is embedded in the update. If you are an old application that has stopped running, removing the update will be a necessary step to restore the functionality of the software.
Cleaning the data of the application "System Update"
The easiest and safest way to try to get rid of an intrusive update is to clean up the data of the system component responsible for loading the packets. This method does not remove the firmware itself, but resets the bootloader state if the update has not yet been installed definitively.
To start, you need to go to the application management menu. Go to Settings → Applications → All applications. In the list, find System Update (or System Updater). If the item is hidden, click on three dots in the corner of the screen and select Show System Processes.
Inside the app menu, find the Clean button and select Clear All or Delete Data. This action will reset the update check and may remove the already downloaded but not installed firmware package.
☑️ Cleaning algorithm updater
It is worth noting that this method is only effective at the stage when the update is downloaded, but not applied. If the system is already updated, a simple data cleanup will not return the old version, but can stop cycling and installing new patches.
Removing the installation APK update file
Often downloaded service pack takes up a significant space in memory and lies in hidden folders of the system. Deleting this file can free up space and prevent the installation from accidentally starting at the wrong time.
Update files are usually stored in the directory. /data/lineage_updates/ or in a folder /downloaded_rom/ To access these hidden system folders, you'll need a file manager with root permissions or a connection through a root. ADB.
If you have superuser rights, use a file manager such as Root Explorer or MT Manager. Find a file with the.zip extension whose name contains the firmware version number and delete it. Once the file is deleted, clear the System Update app cache in the manner described above.
| Location of the file | Type of access | Necessary rights | Risk of removal |
|---|---|---|---|
| /data/lineage_updates/ | Systemic | Root | Low. |
| /downloaded_rom/ | Customized | Normal. | Minimum |
| /cache/ota_package/ | System cache | Root/Recovery | Medium. |
| /MIUI/ | Customized | Normal. | Low. |
Be careful when working with system partitions. Deleting the wrong file can cause system services to fail. Always check the size and date of creation of the file before it is eliminated.
Recovery Mode (Local Update)
A more radical method involves using Recovery Recovery mode, which allows you to install an earlier version of the firmware on top of the current one, but requires prior preparation and the necessary image file.
You need to download the archive from the previous stable version of MIUI for your particular model. The file should have the.zip extension and be called, for example, update.zip. Put this file in the root of the device's internal memory.
Then you need to switch to Recovery mode. To do this, turn off your phone and press the Volume Up + Power key combination. In the menu that appears, select the language (if available) and click on Install update.zip or Select the Service Pack.
What if Recovery says “Can’t verify update”?
The system will check the integrity of the file and begin installing it, which can take 5 to 15 minutes, and when it's done, the phone will automatically restart with the cleaned, older version of the system.
⚠️ Note: When you install an older version of the firmware through Recovery, all data on the device will be deleted. This method involves a complete reset (Wipe Data).
Complete reset and flashing through Mi Flash
If software methods do not help, the only reliable option is to completely reflash the device using the computer and the Mi Flash Tool utility, which allows you to install any version of the software available for your model.
To start, unlock the bootloader through Mi Unlock, without which it will be impossible to install global or older firmware versions. Unlocking can take 3 to 7 days.
Download the Fastboot ROM for your model. Unpack the archive to the root of the C disk so that the path doesn't contain Cyrillic. Launch the Mi Flash Tool, connect the phone to Fastboot mode (clutch Volume Down + Power), and select the path to the firmware folder.
1.Run Mi Flash Tool
2. Connect the device to Fastboot mode
3. Select a path to a folder with unpacked firmware
4.Push the "Flash" button.
5. Wait for the green streak of successIn firmware mode, select the Clean All option to delete all user data and the old system completely. This ensures clean installation without file conflicts.

Use the original. USB-cable USB 2.0 on the computer motherboard for maximum connection stability during firmware.
How to disable automatic updates
After a successful system rollback, it is critical to prevent the automatic updates from being re-installed, otherwise the device will download the unwanted package in the background again.
In System Update, click on the three dots in the top right corner and select Settings. Turn off Auto Update and Notify Updates. It is also useful to turn off Internet access for the Updater system app through the traffic management menu.
You can also use the Developer Mode, turn it on by quickly clicking 7 times on the build number in the About Phone section. Then, in the Developer Menu, look for Automatic System and turn it off if it is present in your Android version.
💡
Complete disabling of updates requires a comprehensive approach: settings within the application, banning access to the network and controlling the rights of the developer.
Be sure to check system status periodically, as major security updates may ignore some settings and force you to install critical patches.
