The situation when after a planned upgrade of the system the smartphone begins to work unstable, familiar to many owners of equipment Xiaomi. Instead of promised improvements in performance and security, users often face increased battery consumption, interface lags or the disappearance of familiar functions.
The operating system rollback process is not a standard function that can be performed with a single click in the settings menu. It is a complex procedure that requires understanding the file structure of MIUI or HyperOS, as well as being prepared for possible risks. It is important to realize that trying to downgrade the software version (downgrade) always involves completely cleaning user data.
In this article, we will analyze proven methods of returning to the old firmware, explain the technical nuances of the bootloader and answer the question whether you can only delete the service pack while saving personal files. Full rollback of the Android version without data loss is technically impossible on modern Xiaomi devices without using specialized TWRP backups. Be careful when reading instructions, as an error at any stage can lead to locking the device.
Why you should remove the update and what are the risks
The decision to roll back the system is often dictated by critical bugs that developers do not have time to fix in patches, for example, after switching to a new version of Android, banking applications or banking applications may stop working correctly. NFC-Users are also often annoyed by the change in the logic of the interface or the appearance of intrusive advertising in the system components.
However, before starting the procedure, you need to weigh the pros and cons. The main obstacle is the anti-Rollback protection mechanism, which is implemented by Xiaomi in most modern models, and it prevents installing an older version of the firmware if the version counter is already updated in the bootloader.
⚠️ Warning: Trying to firmware a device with Anti-Rollback enabled on an older version can lead to the "fixing" of the smartphone. The device will stop turning on, and you will only recover it in the service center through the programmer.
In addition, removing the update implies a complete reset (Wipe Data), all photos, contacts, correspondence and installed applications will be permanently deleted, so pre-backup is a mandatory step, which is unacceptable to ignore.
Also, consider that older versions of firmware may contain security vulnerabilities, and going back, you potentially open the door to malware that has already learned to bypass the new version of security, especially for devices that conduct financial transactions.
Checking the rollback capability and the status of the loader
The first step before any manipulation is to make a detailed diagnosis of the current state of the device, you need to know exactly which version of MIUI or HyperOS is installed now and which version you plan to upgrade to. Information about the current build is in the Settings → About the phone menu.
The key is to check the status of the bootloader. Most firmware change operations require an unlocked Bootloader. If the bootloader is locked, you won't be able to install custom receivers or old official firmware via Fastboot. You can check the status by going to Fastboot mode (clamping the volume button when turned on) or through special applications.
☑️ Check before rollback
Global firmware (Global) often has a lower version number than China, but a higher Anti-Rollback index. Attempting to install global firmware on top of Chinese or vice versa can be regarded by the security system as an attempt to downgrade.
To check version compatibility, use the table below, which gives examples of limitations for different series of devices:
| Device series | Current version | Target version | The risk of blocking |
|---|---|---|---|
| Xiaomi 13 / 14 | HyperOS 1.0 | MIUI 14 | Critical (Anti-Rollback) |
| Redmi Note 12 | MIUI 14 (Global) | MIUI 13 (Global) | High-pitched |
| Poco F5 | MIUI 14 | MIUI 14 (China) | Medium (Regional lock) |
| Xiaomi 11T | MIUI 13 | MIUI 12.5 | critical |
If you are not sure about the status of Anti-Rollback for your particular model, it is better to refrain from experimenting.Information about downgrade support is often scattered and depends on the specific region of release of the smartphone.
Local Update Method: Install an older version
The safest, though not always working, way is to use the built-in Local Update feature, which allows you to install the firmware archive manually, but the system usually only allows you to install the same or a newer version, but in some cases, if the versions match on the security index, this method works.
First, you need to find and download the full firmware archive (Recovery ROM) of the desired version. The file should have a.zip extension and weigh about 4-5 GB. Important: it should be a Recovery firmware, not a Fastboot. Place the file in the root of the internal memory of the device.
Where do you find old firmware?
Then activate the hidden menu. To do this, open the Update app, click on the three-point in the corner and select Select File. If there is no such option, you need to quickly click on the MIUI version in the center of the screen several times until the notification “Additional Features Enabled” appears.
Once the file is selected, the verification process will begin, and if the system issues an error such as “Failed to check the update” or “Installed version is newer”, the security mechanism has worked and this method will not work, in which case only the option with the unlocked bootloader and Fastboot mode remains.
⚠️ Warning: Never interrupt the installation process, even if it is frozen in 99%. interruption of system partition writing is guaranteed to cause software failure.
Recoil from Fastboot and Mi Flash Tool
If standard methods don't work, the only option is to use the Mi Flash Tool on your computer, which requires an unlocked bootloader and ADB/Fastboot drivers, and allows you to roll out the old firmware cleanly, ignoring some checks, but not all.
First, download the Fastboot archive. ROM It has the extension.tgz. Unpack the archive to the root of the C disk so that the path to the folder is Cyrillic-free and short, like this: C:\ROM\. Long tracks can cause errors when recording.
💡
Use the original. USB-cable and connect your smartphone directly to the motherboard port (back of the PC), avoiding USB-Hubs and front panels of the case, which will provide stable power and data transmission.
Launch the Mi Flash Tool on behalf of the administrator. Transfer the phone to Fastboot mode by pressing the volume down button when connected. USB-In the program, click the "Refresh" button to determine the device. At the bottom of the window, select the cleaning mode: "Clean all" or "Clean all and lock" (delete everything and lock the bootloader).
Choosing a Clean all and lock mode will return the phone to factory status with the bootloader locked, but only use it if you are sure that the firmware fully matches the region of the device. Otherwise, the phone can go into endless restart (bootloop).
The firmware process takes 5 to 15 minutes, and once completed, the device will automatically restart, and the first time you turn on the old system, it can take up to 10 minutes longer than usual.
Resetting settings as an alternative to deleting
Often users want to remove the update not because of critical bugs, but because of temporary glitches that occur immediately after the update.The system re-indexes files, caches data and optimizes applications, which causes heating and brakes, in which cases a complete reset can solve the problem without the risk of downgrade.
Resets are available via the Recovery Mode menu, and turn off your phone and press the Volume Up + Power button combination. From the menu that appears, select the language (usually English and Chinese) and click Wipe Data → Wipe All Data.
This method deletes all user data, but leaves the operating system version unchanged. Once reset and cleanly set up, the phone often works faster and more stable than before the update, as conflicts between the old settings and the new system code disappear.
💡
Wipe Data solves 80% of performance problems after an update, making an attempt to roll back the version unnecessary in most cases.
If the problems persist after reset, then it is precisely the errors of the new version of MIUI that are the cause, and then a return to the previous build remains the only way out.
Data recovery and system setup
After successfully removing the update and returning to the old firmware version, you will have a clean welcome screen, at which point it is important to properly recover data so as not to transfer potential debris or conflicting settings back to the system.
Use the built-in Mi Mover feature to transfer data from another device or restore a backup from the Mi Cloud or Google cloud. However, it is better to install the apps again from Google Play, rather than restore their full cast to avoid cache errors.
Pay attention to the security settings. After a system rollback, some banking applications may require re-binding the device or not running due to changed security settings. NFC-Payment may require additional adjustments.
