Modern Xiaomi smartphones running MIUI shells or the new HyperOS often receive automatic updates that are designed to improve the functionality of the device. However, in practice, users often face a situation when after installing a new version of the firmware, the gadget begins to work unstable, discharges faster or loses familiar functions.
The process of uninstallation of the system update is a complex procedure that requires care and strict follow-up to the instructions, since the Android operating system does not have a standard βdeleteβ button for already installed patches. Restore the previous version is possible through special download modes, using computer utilities or reflashing through Recovery. It is important to understand that any manipulation of system files carries risks, so before starting any actions you need to carefully weigh the pros and cons.
In this article, we will take a closer look at all the available methods of rollback, explain the difference between resetting and full flashing, and provide tools to minimize risks. You will learn how to prepare the device, what files will be needed and how to perform the procedure correctly so that your smartphone will work again like a clock. Xiaomi provides several ways to solve the problem, but the choice of the specific method depends on the current version of the software and the state of the bootloader blocker.
Analysis of the situation: when you really need a rollback of the system
Before taking drastic measures, you need to make sure that the problem lies in the update, not in hardware failure or application conflict. Often users rush to conclusions, although the situation can be corrected with milder methods.
β οΈ Warning: If your smartphone just started to run slower, try clearing the cache first or resetting to factory settings without reinstalling the system.
There are several scenarios where software interference is inevitable, such as a new version of Android that may not work properly with installed apps, or a developer has made a mistake in the camera drivers, in which case returning to the previous build is the only working solution.
- π A sharp drop in autonomy: the battery is discharged in a few hours instead of a day.
- π‘ Communication problems: network goes missing, Wi-Fi or Bluetooth is down after update.
- π± Instability of the interface: constant launcher flights, touch screen hovers.
- πΈ Camera errors: Camera app closes or takes blurry pictures.
Also, some updates change the structure of file partitions, making direct rollback impossible without a complete data cleanup. The Anti-rollback version plays a key role here: if it was upgraded in a new update, you will not officially install the old firmware. Always check the forums and specifications of a particular model before starting work.
Device preparation and data backup
Any operation to change the system software requires a mandatory backup. The process of removing the update often involves completely cleaning the memory of the smartphone, so saving contacts, photos and documents is the number one priority.
To create a backup, you can use built-in MIUI tools, Google cloud services or third-party programs for the PC. The most reliable way is considered a combined approach: important documents are saved to the computer, and system settings and application list are synchronized with the Mi Account account, which will quickly restore the functionality of the gadget after the procedure.
βοΈ Checklist for rollback preparations
Make sure the USB cable you use to connect to your computer is healthy and supports data transfer, not just charging.A damaged wire can interrupt the firmware process at the most critical moment, with serious consequences.It is also recommended to free up space on the internal drive if you plan to download the firmware file directly to the device.
- πΎ Copy photos and videos on PC or in the cloud (Google Photos, Mi Cloud).
- π Export contacts to.vcf and save the file separately.
- π Remember or write down passwords from Google and Mi accounts, they will be needed for authorization.
- π Charge your smartphone to a level of at least 60-70% avoidance.
Pay special attention to two-factor authentication. If you reset settings, you may need a confirmation code that will come to the SIM card or the authenticator application. Make sure that the SIM card is active and installed in the phone, or the access codes are stored in a safe place.
Recovery Mode (Wipe Data) Reset Method
The easiest and most affordable way to try to fix bugs that have occurred after an update is to reset the data via the Recovery Mode menu, which does not remove the update itself completely, but clears all user data and cache that may have conflicted with the new version of the system, often helping to restore stability to the device without complex flashing.
To enter recovery mode, you need to turn off your smartphone and pinch a certain combination of buttons. On most Xiaomi models, this is the simultaneous pressing of the volume and power button. Hold them until the Mi logo or menu appears in English/Chinese. Navigation is done with volume buttons, and the choice is with the power button.
| Action. | Button combination | The result |
|---|---|---|
| Entrance to Recovery | Volume + and Nutrition | Recovery menu |
| Entrance to Fastboot | Loudness - and Nutrition | Loader mode |
| Data resetting | Choice of Wipe Data | Delete all files |
| Reboot. | Reboot's pick | Starting the system |
In the Recovery menu, select Wipe Data and then Wipe All Data. The system will ask you to confirm the action, after which the cleanup process will begin. Important: this step will delete all personal files, so having a backup is critical. Once the process is complete, select Reboot to reboot.
What to do if you recover in Chinese?
Once reset, the phone will start as new, and you'll need to go through the initial setup, and if the problem was caused by accumulated debris or a setting conflict, the device should work stably, and if the errors persist, deeper intervention will be required.
Reverse the firmware version via Fastboot and Mi Flash
If a standard reset didnβt work, the only option is to completely reflash the device to an earlier version of the software using the Mi Flash Tool.This method allows you to βremoveβ the current update by replacing it with an old, stable build. To do this, you will need a Windows computer and a firmware file in.tgz format (Fastboot ROM), which you need to download from the official website or trusted sources.
The first step is to put the smartphone in Fastboot mode. To do this, turn off the device, press the volume button and connect the device. USB-The screen will show a picture of a hare in a hat-eared, indicating a successful entry into bootloader mode. ADB Fastboot is installed on PC correctly.
fastboot devicesThis command in the command line will check if your computer sees your device. If the serial number is displayed, you can run the Mi Flash Tool. Download the archive with the firmware, unpack it to the root of the disk (the path should not contain Cyrillic alphabets) and select in the program. It is critical to choose the "Clean All" mode to avoid partition compatibility errors.
β οΈ Note: When the Downgrade version is rolled back, the bootloader blocker must be unlocked. On the blocked bootloader, installing an older version of the software is impossible due to the Anti-rollback policy.
After you select the file and mode, press the Flash button. The process will take 5 to 15 minutes. Don't turn off the cable or interrupt the program. Upon completion, the phone will automatically restart with a cleaner, older version of the system. This is the most reliable way to remove a problematic update.
- π₯ Download Fastboot ROM It is for your model (code name should be the same).
- π» Install Xiaomi drivers and ADB computer.
- π Make sure the bootloader is unlocked (otherwise the rollback will not pass).
- π« Do not interrupt the firmware process and do not touch the cable.
Disabling Automatic OTA Updates
Once you've successfully returned to a stable version, the main challenge is to prevent the problem update from being re-installed automatically. MIUI and HyperOS insist on upgrading, and to "remove" this feature, you need to block the update services, by disabling system applications and cleaning their data.
Go to your smartphone settings, select the Apps section and click All Apps. In the upper right corner of the menu, select Show System Processes. Find the Updater or MIUI Update app in the list. Log in and click Stop and then Clear.
π‘
You can use updates to securely block ADB-Command: pm disable-user --user 0 com.android.updater.This will disable the system update module until the next flashing.
Next, go to the Permissions menu and deny the application access to the network (Wi-Fi and Mobile Data). This will prevent the update bootloader from contacting the server. Also in the update menu itself (Settings β About Phone β MIUI version), you can click on the menu icon (three dots) and select Settings where to disable Auto Update and Notifications.
Some users prefer more radical methods, such as renaming the apk update file through root rights, but this can disrupt the integrity of the system. Just restrict access rights and clear the data so that the system forgets that there is a new version. Periodically check this section, as after major security updates, the settings may reset.
Possible risks and problems solving in the rollback
The procedure for removing the update and rollback of the system is not without risks. The most common problem is the version verification error (Anti-rollback protection). If the new firmware has upgraded the bootloader version (ARB), the security system will block the installation of the old version to prevent vulnerabilities, in which case the error message will appear on the screen and the process will be interrupted.
Another risk is the loss of warranty if you unlock the bootloader for the procedure. Xiaomi official service centers can refuse free repairs if they find traces of software interference. However, in most cases, flashing to the official global or Chinese version is not a reason for refusal, unless the system partitions have been changed by non-standard methods.
- β Anti-rollback error: Trying to install firmware with lower security index.
- π Account Lock: If you do not log out of Mi Account before resetting, protection will work.
- πΎ Data loss: when you select the "Clean All" mode, all information will be destroyed.
- π Battery discharge: interruption of the process due to a dead battery can "brick" the phone.
If there is an error in the firmware process, try changing it. USB-A port, cable, or version of the Mi Flash Tool. Sometimes it helps to run the utility on behalf of the administrator. In case the phone stops turning on (bootloop), you will need to log in to Recovery mode to reset or re-rout the firmware through Fastboot.

The main risk of rollback is blocking the Anti-rollback. Always check the bootloader version before installing the old firmware, otherwise the phone may turn into a brick.
In conclusion, removing the update on Xiaomi is an effective way to regain comfort if the new version turns out to be buggy. By following the instructions for backing up, using Fastboot and blocking OTA, you can secure your device. Remember, stability is more important than having the newest but raw features.
