Many users of Xiaomi, Redmi and POCO smartphones face a situation where, after an automatic system update, the device starts to work unstable, there are errors in the interface, the battery quickly drains or important functions that were in the previous version disappear, in which case the only effective solution is to return to a more stable version of the operating system.
The firmware rollback procedure, or downgrade, requires careful attention and strict adherence to the algorithm of actions. Wrong steps can lead to data loss or software failures, so it is important to prepare all the necessary tools and files in advance. In this article, we will discuss safe methods for returning to the previous version of MIUI or HyperOS using standard tools and specialized software.
Before you start taking action, you need to understand which method is right for your case. There are several ways: through the built-in Recovery menu, using the computer and the MiFlash utility, and also through the Fastboot mode. The choice depends on the current lockdown of the bootloader and the availability of recovery files on the manufacturer's servers.
Reasons and Need to Return to Old Version
The main reason users are looking for a way to roll back firmware on Xiaomi is the emergence of critical bugs in new builds. Developers often release updates with new features, but sometimes forget to test the stability of the work on all device models. This leads to cyclic reboots or “hanging” interface, making using the smartphone impossible.
Another factor is loss of functionality, such as the new version of the shell can remove the ability to install applications from unknown sources without complex manipulation or change the logic of notifications. For many users, the familiar environment is more important than new but inconvenient experiments of developers.
It is also worth considering compatibility with banking applications and security systems. Sometimes new security patches conflict with installed software, causing Google Play Protect certification errors. In such situations, returning to a time-tested version is the only solution to restore the device to full functionality.
Preparation for the downgrade procedure
Before any manipulation of the system partition, you need to back up your data. The rollback process almost always involves completely cleaning the internal memory of the device. Save contacts, photos and documents to the cloud or to the computer so that important information is not lost irretrievably.
The second important step is to charge the battery, and the charge level should be at least 60-70%, and interrupting the process of writing system files due to battery discharge can lead to the fact that the phone turns into a brick and require complex hardware repairs in the service center.
You also need to download the current firmware archive, and it's important to look for the version you want to return to, the files should be designed strictly for your device model, and using the firmware from another smartphone can permanently incapacitate your gadget.
☑️ Preparation for rollback
To work with your computer, make sure that you have ADB and Fastboot drivers installed. Without them, your PC will not be able to properly interact with your phone in bootloader mode. This is a basic requirement for using the MiFlash utility, which will be discussed below.
Method 1: Recovery Mode (without PC)
The easiest way most users can use is through built-in recovery mode, but it only works if the firmware version you want to upgrade to is newer or equal to the one installed in Recovery but older than the current system, often blocked by Anti-rollback protection.
To start, download the firmware archive in ZIP format and place it in the root of internal memory or on an SD card. Rename the file to update.zip if the instruction for your model requires that name. Then go to Settings → About Phone → MIUI version and click on three dots in the corner of the screen.
Select "Select a firmware file" and specify the downloaded file. The system will check the file and, if the version allows rollback, prompt you to start updating. If you see an error or ban message, then this method is not suitable for your situation and you will need to use Fastboot.
⚠️ Warning: If the phone says "Can't verify update" or "Current version is newer," it means that the Anti-rollback protection prohibits rollbacks by this method.

Method 2: Using MiFlash and Fastboot Mode
The most reliable and versatile way to roll back the MIUI version is to use the MiFlash Tool utility on your computer, which allows you to completely rewrite the system partition, ignoring some limitations, but requires an unlocked bootloader (in most cases).
First, turn your smartphone into Fastboot mode. To do this, turn off the device and press the power and volume buttons at the same time. The screen will show an image of a rabbit repairing an android, or the inscription: FASTBOOT. Connect your phone to your computer through high-quality USB-cable.
Launch the MiFlash Tool and press the Refresh button. If the drivers are installed correctly, your serial number device will appear in the list. Press Select and select the folder with the unpacked firmware (not the archive, but the file folder). At the bottom of the window, select Clear all mode to avoid file conflicts.
| Firmware mode | Data retention | Recommendation |
|---|---|---|
| Clean all | No (full reset) | Recommended for rollback |
| Save user data | Yes. | Not recommended for downgrade |
| Clean all + lock | No + lockdown | Only for global versions |
After selecting the mode, press Flash. The process will take 5 to 15 minutes. Do not turn off the cable or touch the phone until the green "Success" sign appears.
💡
Use the original cable or quality analogue. Cheap charging cables often don't have data lines, which will cause a connection error in MiFlash.
Mistakes in reflashing and their solution
Downgrades often involve error codes, and one of the most common is Flash All Except Data Storage or verification errors, which occur when the hash amounts of the files do not match or the bootloader version does not match the system version.
If MiFlash is making an error at the end of the process, try changing it. USB-port on the computer (it is desirable to use ports) USB 2.0 at the back of the system unit) or replace the cable. MTK depending on the processor of your device.
Sometimes there is a problem with a lack of space on the system partition when trying to write data, in which case you need to manually clear the partitions through the ADB command line before starting the firmware, this requires certain skills in working with console commands.
⚠️ Warning: Never interrupt the recording process, even if it seems to be getting stuck. 90-99% The process is guaranteed to lead to a software breakdown of the device.
bootloader lock and regional restrictions
The important aspect is the type of firmware. You can't just roll back from the global version (Global) to the Chinese version (China) or the Indian version (India) without unlocking the bootloader and completely cleaning it up. Moreover, trying to reflash the region without unlocking can lock the device at the server level.
If the bootloader is locked, you have two options: wait for unlocking through the official Mi Unlock website (requires account binding and wait 7 to 30 days) or look for workarounds that are often closed by the manufacturer. For global versions, rollback to the older global version is sometimes possible with a closed bootloader through Recovery, if Anti-rollback allows.
Users who have purchased AliExpress devices with global firmware installed over Chinese should be especially careful, and rolling back to the original Chinese version can be difficult, as it requires flashing with changing regional flags.
💡
Unlocking the bootloader is a key step for free firmware management, but it voids the warranty and requires a data reset.
