Xiaomi smartphone owners often face a situation where, after the arrival of the next MIUI or HyperOS update, the device begins to work unstable, the battery runs out in a few hours, the interface slows down, and the usual applications fly out for no apparent reason. In such cases, the only sensible solution is to return to the previous, more stable version of the operating system, a process technically called downgrade and requires careful attention to detail, since careless actions can lead to data loss or software errors.
Xiaomi has put strict restrictions on installing older firmware versions on top of new ones for the sake of user safety. Standard methods through the update menu can not do this - the system will simply give an error or refuse to start installation. So you will have to use more advanced tools such as Fastboot or Recovery mode. It is important to understand that in most cases, rolling back the version will entail a complete cleanup of internal memory, so pre-creating a backup is a critical stage of preparation.
Before you start taking action, you need to make sure you have accurately identified your device model and the current version of the software. Build information is in Settings → About the phone. Write this data down, because you will need to look for a specific firmware file that is compatible with your hardware. Using an inappropriate file can cause the phone to turn into a brick and stop responding to commands.
Preparation for rollback procedure
The success of a downgrade operation depends 90% on quality preparation. The first step is to find and download the right firmware archive. The official files are available on the MIUI bootloader website or proven resources like the Xiaomi Firmware Updater. You need a full archive like Recovery ROM (.zip extension) to install through the phone menu or Fastboot ROM (.tgz extension) for firmware through your computer. Make sure that the download version is really older than the one you have installed now.
Then you need to back up all the important data. Since the internal memory will be fully formatted during the rollback process, all photos, contacts, messaging and files will be permanently lost. Use Google Drive, Mi Cloud or third-party backup software on your computer. Also make sure that the battery is at least 60% so that the device does not turn off at the most inopportune time.
- 📥 Download the full firmware archive (Recovery or Fastboot) strictly for your model.
- 💾 Save all important data to an external medium or to the cloud.
- 🔋 Charge your smartphone to a minimum 60-70% beforehand.
- 📂 Check the integrity of the downloaded file, making sure it weighs 3-5 GB.
☑️ Checklist of preparations
⚠️ Note: The use of firmware from other models or regions (e.g. firmware from the Chinese version to the global version) is strictly prohibited.
Recovery Menu Recovery Method (without PC)
This method is suitable for cases where the difference between the firmware versions is small, or if the device does not lock the bootloader for certain regions. ZIP-But it's worth noting that on the modern versions, it's a good idea to use the engineering menu. MIUI 12, 13, 14, and HyperOS are often blocked by security if you are trying to install an older version.
To start, place the downloaded firmware file (which should be called update.zip) in the root directory of the smartphone's internal memory. If the file has a different name or is in a folder, rename it and move it. Then go to the update menu and click on the tripod in the corner of the screen. Select "Select firmware file" and specify your archive. After confirmation, the file will be checked.
If the system says that the version is older than the current one and the installation is not possible, this method does not work for you, and you will have to switch to using the computer. In the rare cases when the check is successful, the phone will suggest restarting for installation. Accept, and the process will go automatically. Do not interrupt it or touch the device until fully turned on.
Why is the system blocking the installation?
Fastboot and Mi Flash Tool
The most reliable and versatile way to roll back the update on Xiaomi is to use the Mi Flash Tool utility on your computer. This method requires an unlocked bootloader. If your bootloader is blocked, you will first have to go through the official unlock procedure through the Mi Unlock site, which can take from 3 to 7 days of waiting. Without an unlocked BL, you will not be able to install the old firmware.
After obtaining the unlock status, download and install drivers. ADB/Fastboot Unpack the archive with Fastboot firmware (the folder must contain images, bat, txt files) into the root of the disk, preferably in a short way, for example, C:\mi_rom. Connect the off smartphone to the computer, clamping the power and volume buttons at the same time to enter Fastboot mode (there will be a hare repairing the android on the screen).
Launch the Mi Flash Tool on behalf of the administrator. Press the Refresh button and the program must identify your device. In the lower right corner, select clean all mode. This is a prerequisite for downgrade. Press Flash and wait for the process to end, which will take 100 to 300 seconds. The phone will automatically reboot with a cleaner, older version of the system.
Problems with Anti-Rollback and bootloader lock
One of the main obstacles in downgrade is the Anti-Rollback mechanism, which is a security built into the bootloader that prevents the installation of firmware with a lower security index than it is currently installed. If you try to flash a device that violates this rule through Fastboot, you run the risk of getting a brick-and-mortar machine that can not be restored by software.
Locking the bootloader is the second important aspect. On global versions of Xiaomi smartphones, the bootloader is locked by default. This is done for security, but it prevents enthusiasts from changing the software. To roll back the update, you will definitely need Unlocked status. If you bought the phone from hand, check the status in the Settings menu → About the phone → The MIUI version by quickly clicking on the logo. If it says “Locked”, you can not do without an official unlock through the binding to the Mi Account.
| Parameter | Blocked BL | Unlocked BL |
|---|---|---|
| Installation through Recovery | Only official new | Any compatible |
| Installation via Fastboot | Impossible. | Maybe (Clean All) |
| Risk of data loss | Low (with a regular update) | 100% downgrade |
| Guarantee | It's still there. | Could be revoked. |
💡
You can check the status of the bootloader by connecting the phone in Fastboot mode to the PC and running the command in the command line: fastboot getvar all.
Data retention and recovery after reset
Once the update is successfully rolled back, your smartphone will appear as a blank slate. All user data will be deleted. The initial setup process will take time, but this is necessary for the system to work smoothly. When you first turn on, the system will suggest restoring data from a Google backup or Mi Cloud. If you made a local backup through the built-in MIUI, it can be restored later through the settings menu.
Pay attention to the applications of banks and payment systems. After changing the firmware version and especially after unlocking the bootloader, some banking applications may stop working due to security breaches Google Play Protect. You may need to additional configuration through Magisk (if you use root rights) or wait for updates from banks that will add your device to the list of compatible.
Don't rush to install all the apps at once. Let the system run a couple of hours in the background to index files and configure services. This will help avoid the false suspicion that the downgrade failed. If the battery is still behaving strangely, try resetting the network settings or performing a reset on clean firmware.
⚠️ Warning: After unlocking the bootloader, some features, such as high quality video recording in the camera or Widevine work L1 (HD Netflix may stop working on some models.
Frequent mistakes and ways to solve them
In the rollback process, users often encounter the error "Can't verify update" when trying to install through Recovery. This means that the digital signature of the file does not match the expected one or the version is too old. The solution is one - to switch to the method with the computer and Fastboot. Another common problem is hanging on the Mi or Android logo after firmware, in which case it helps to log into Recovery mode (power and volume buttons up) and select Wipe Data.
Sometimes the Mi Flash Tool gives off a "Flash All Except Data Storage" error or just doesn't see the phone. USB — It should be high-quality and support data transfer, not just charging. USB-port, preferably USB 2.0, and reinstall the drivers ADB. Also make sure that the path to the firmware folder does not contain Cyrillic characters or spaces.
💡
The most common reason for a botched rollback is to try to do so without the bootloader unlocked.Always check BL status before starting the procedure.
