How to roll back MIUI to the previous version: step-by-step instructions

Xiaomi smartphone users often face a situation where, after updating the operating system, the device begins to work unstable, discharge faster or lose familiar functions. Downgrade is the process of returning to an older but stable version of software that can save your gadget from constant failures. However, this procedure requires care and strict follow the instructions, as erroneous actions can lead to data loss or lock the bootloader.

In this article, we will explore in detail whether MIUI can be rolled back to an earlier version without unlocking the bootloader, what are the limitations for global and Chinese firmware, and alternative methods for restoring functionality. Software version change is not just installing an old file, but a complex process that affects the structure of memory partitions and device security.

Before we take action, we need to realize that smartphone manufacturers are actively implementing rollback protections known as Anti-Rollback. Ignoring these restrictions can turn your phone into a brick, so every step should be considered. We have prepared a detailed algorithm of actions that will help minimize the risks.

Risk analysis and anti-Rollback testing

The first and most critical step is to check that Anti-Rollback is on your device, and this technology blocks the installation of a firmware with a lower security version index than the one currently installed, and if you try to flash a device that violates this rule through Fastboot mode, the smartphone can be permanently locked.

Check for protection in the About Phone menu, where you need to click on the kernel version or MIUI version several times to see detailed information. You are interested in the Anti parameter or the Security version index. If the current index is 4, and the firmware file you want to install is 3 or less, then installation is impossible without special tools and unlocked bootloader, and in some cases it is impossible at all.

⚠️ Note: Trying to run through the Fastboot version with a lower Anti-Index than the current one can lead to a Hard Brick device.Always check build numbers before starting the procedure.

There is also the notion of regional firmware binding: Global and Chinese versions have different partition structures; trying to install Chinese firmware on a global device (or vice versa) without changing the region (Cross-flash) often requires an unlocked bootloader and complete data cleanup, which in some cases can cause problems with the operation of banking applications and Google services.

Preparation for rollback procedure

The success of the operation depends on the quality of preparation. Before you start downgrading MIUI, you need to perform a number of mandatory actions, ignoring which can lead to the loss of photos, contacts and passwords.

You will need a stable Internet connection to download the necessary files, as well as free space on the internal drive or computer. It is recommended to charge the device to a minimum of 60-70%, since interruption of the firmware process due to battery discharge is one of the common causes of errors.

Make sure to back up all your important data. You can use the built-in Mi Cloud, Google Drive, or just copy files to your computer. Once you roll back, all the data will be deleted and it will not be possible to restore it without a backup, and you should also remove the device's link from your Mi Account or know the password from it, because after the reset, the system will require authorization.

Recovery method through the update menu

The safest and easiest way to do this, which doesn’t require a computer and an unlocked bootloader, is to use a built-in update mechanism, but this only works if the version you want to roll back to is newer or equal to the current version of the bootloader, and if the firmware file is in the correct format.

To start, download the Recovery firmware archive for your model. The file should be complete, not an over-the-air update (OTA). Put the downloaded archive at the root of the device's internal memory. If you use an SD card, you can also place the file there, but you can use internal storage more reliably.

Next, go to Settings → About Phone → MIUI version. Click on the three dots in the top right corner of the screen and select Select firmware file. Find the downloaded archive and confirm the action. The system will check the file, and if rollback is allowed, the Update button will appear.

💡

If the Update button doesn’t appear or the system says the file is corrupt, then the downgrade protection is turned on or the file is not suitable for your region, in which case only the Recovery mode through the buttons will help.

If the standard path blocks the installation, you can try the forced verification method. To do this, in the firmware file selection menu, click on the MIUI version icon 10 times until the message “Additional features are activated” appears. Then the three-point menu will see “Select firmware file”, which sometimes allows you to bypass the version verification restrictions, but not Anti-Rollback protection.

Using Recovery Mode for Resetting

If you can't install through the settings, you can use Recovery mode, which is available on any Xiaomi device, which requires renaming the firmware file and doing certain button actions, and is effective when you need to completely clean the system and install a fresh image.

Copy the firmware file (.zip) into the device's internal memory. Rename the file to update.zip if it has a different name. Turn off the smartphone completely. Press the Volume Up and Power buttons simultaneously before the Mi logo appears, then release the power button, continuing to keep the volume up until the Recovery menu appears.

In the Recovery menu, you can control the volume buttons (up/down) and the power button (select). Select a language (usually English or Chinese), then go to Wipe Data and clean it. After that, select Connect with MIAssistant (if you need a PC connection) or try to find Install Update (not available in all versions of Recovery).

⚠️ Attention: In stock Recovery mode, there is often no possibility of installing firmware with a lower version of Android or MIUI. If the system gives an error “Can’t verify update”, you will need an unlocked boot loader.

Recoil with Fastboot and Mi Flash Tool

The most powerful and versatile method to roll back on any version is to use Fastboot mode and the Mi Flash Tool utility on your computer. This method requires an unlocked bootloader. If the bootloader is locked, the tool will give an error, and you will have to wait 168 hours (7 days) after submitting your application to Mi Unlock.

Download and install drivers ADB/Fastboot Download the firmware image in Fastboot format (extension.tgz), unpack the archive on your computer. It is important that the path to the folder does not contain Cyrillic alphabets and spaces, for example: C:\Xiaomi\ROM\.

fastboot devices

This command, entered in the command line, will help check the connection with the device. Put the phone in Fastboot mode by clamping down Volume + Power buttons. Connect the cable to the PC. In Mi Flash, press Refresh, select the path to the unpacked firmware. At the bottom of the window, select Clean All mode - this is mandatory when changing versions or regions.

Press the Flash button. It takes 200 to 600 seconds. Don't turn off the cable or touch the phone. Once complete, the device will automatically restart. It can take up to 10 minutes to start up.

Problems of compatibility of regions and versions

A common problem with rollbacks is regional incompatibility: Global firmware (Global Stable) is based on one version of Android, while Chinese (China Stable) or Indian (India) may have different partition structure. Trying to “overlay” the firmware of another region on top of the current one without full cleanup (Clean Install) often leads to a cyclic reboot (bootloop).

If you are moving from the Chinese version to the global one, be sure to use the method with complete data cleaning. Otherwise, there may be system application conflicts, camera or communication module inoperability, and it is worth considering that the global versions may not have some features present in Chinese builds, such as recording default calls or specific themes.

Changing from Global to China or back often requires manually changing the region in the Settings menu → Additional settings → Region before installing, although using Mi Flash with clean all mode this happens automatically. However, if you use the method through Recovery, pre-region change can help the system accept the update file.

💡

Cross-regional firmware (e.g. Global on China) always requires an unlocked bootloader and a full-clean-all Flash mode.
