How to return the old firmware version to Xiaomi: the complete guide

Modern Xiaomi smartphones regularly receive updates designed to improve security and add new features. However, in practice, it often happens that the new version of MIUI or HyperOS is unstable, causes overheating or simply does not like the user with its appearance.

The downgrade process requires attention, as it is technically more complex than a conventional “over-the-air” update, you will have to interact with system partitions of memory and possibly use the computer to execute special commands.

Before you start taking action, you need to realize that returning old firmware to Xiaomi almost always means completely erasing user data, a security measure that prevents conflicts between different versions of the file system, so creating a backup is not just a tip, but a prerequisite for starting work.

Why You May Need to Reverse a Software Version

Users often experience a situation where, after an automatic update, the smartphone behaves unpredictably, the battery runs out in a few hours, the interface slows down, and the usual applications fly out, these are classic signs of bugs in the new build that developers have not yet managed to fix.

Sometimes the problem is not optimization, but changes in the algorithms of the camera or communication module, for example, after an update, LTE frequencies in your region may disappear or the quality of night shooting deteriorates, in which case returning to the verified version is the only way to restore the functionality of the device.

There is also a category of enthusiasts who just don't like the visual style of the new shell. HyperOS is very different from MIUI 14, and not everyone is willing to put up with changes in the design of the notification curtain or the settings menu.

⚠️ Warning: Trying to install an older version of the system on top of a new one without first cleaning up the data can result in an endless reboot cycle (bootloop).

Preparation of device and computer

The foundation of successful recovery is the proper preparation of the workplace. You will need a Windows computer, because the basic tools for working with Fastboot and Recovery work best in this environment. Using macOS or Linux is possible, but requires additional manipulation of the drivers.

Be sure to check the battery charge of the smartphone. It should be charged at least 60-70%, the process of flashing energy intensive, and if the device turns off at the time of writing system partitions, the consequences can be fatal for the bootloader. USB cable should be of quality, preferably original, to ensure a stable connection without breaks.

Make a full backup of all important data. Photos, contacts, instant messaging will be destroyed as you clean up your Data and Cache partitions. Use Mi Cloud or Google Drive cloud services, or copy files directly to your computer's hard drive.

Pay special attention to installing drivers. For the smartphone to work properly in debugging and firmware mode, you need ADB and Fastboot drivers. Without them, the computer simply will not see the device in the right mode, and all commands will be ignored.

Unlocking the bootloader: the critical stage

Xiaomi’s official policy prohibits older firmware versions from being installed on a locked bootloader, which is designed to protect users from vulnerabilities and ensure system integrity, so the first step is to unlock Bootloader.

To do this, you will need a Mi Account that must be tied to the device for at least 7 days (sometimes the wait time is up to 30 days), the procedure is performed through the official Mi Unlock Tool utility. In the phone developer menu, you need to activate the “Unlock the bootloader” option and enter account details.

It is important to understand that unlocking the bootloader automatically resets all data on the device and removes the security guarantees of some banking applications. Once unlocked, Google Pay or Mi Pay may stop working as standard, requiring additional security settings (Magisk, etc.).

Finding and downloading the right firmware

Choosing the right firmware file is half the success. You don't just need an "old version," you need a specific build that's newer than the one you're currently installing, but older than the one you want to return, or a special version for cross-regional updates. For Xiaomi, there are two main types of firmware: Recovery and Fastboot.

The most common way to roll back a version is to use Fastboot firmware (files with the.tgz extension) to perform a clean installation with full partition formatting. Recovery firmware (.zip) in most cases will not allow you to roll back without special modifications or superuser rights.

Search files should only be on proven resources, such as the official forum Mi Community or authoritative portals like XiaomiFirmwareUpdater. Downloading modified builds from third-party forums carries the risk of malicious code.

💡

Pay attention to the firmware region (Global, EU, CN, RU). Installing Chinese firmware on a global version of the device requires an unlocked bootloader and may result in the absence of some communication frequencies or notifications from applications.

The method of rollback via Fastboot (from the computer)

This is the most reliable and versatile way to bring back the old version of MIUI. It requires unpacked firmware and a PC-mounted ADB/Fastboot toolkit. Put your smartphone into Fastboot mode, clamping down the power and volume buttons at the same time when the device is off.

Connect your phone to your computer. Open the command line or terminal in the tool folder and type in the connection check command:

fastboot devices

If you see the serial number of the device, you've got the connection, you can start the firmware now. If you're using a standard firmware script (usually, it's a good idea to use it). flash_all.bat For Windows, just run it. However, forced rollbacks sometimes require manual partition cleaning.

Critical point: before installing the old system, you need to clear the userdata partition.

fastboot erase userdata

After cleaning, you can start the process of writing a new (old) system. Make sure that the firmware script or in your manual commands is present for formatting, otherwise the installation will be interrupted by an anti-rollback error.

⚠️ Warning: Never interrupt the firmware process, do not turn off the cable USB Do not press buttons on your phone until the progress bar on the command line reaches 100% and the words "Finished" appear".

💡

Using Fastboot mode is the only guaranteed way to bypass the anti-Rollback version check if the bootloader is unlocked.

Alternative methods and working with Recovery

There is a method of rolling back the Recovery menu without using a computer, but it only works in cases where the system usually blocks the installation of an older version, giving an error "Can't verify update." However, if you rename the firmware file or use special scripts inside the system, circumvention is possible.

To do this, you need to put the Recovery ROM file in the root of internal memory (or on an SD card), rename it to update.zip, and select the option “Install update from storage” from the Recovery menu. If the standard method does not work, some users resort to installing custom Recovery (for example, TWRP), which does not check the firmware version.

Installation of TWRP requires an unlocked bootloader and is performed via Fastboot by fastboot boot twrp.img (for temporary launch) or fastboot flash recovery twrp.img (for permanent installation). In a TWRP environment, you can make a full backup of the current system (Nandroid backup) before any experiments.

Possible errors and their solution

During the rollback process, users often encounter a STATUS 7 error or a message that they cannot verify, which means that the security system prevents installation, and the only solution is to use the Fastboot method with complete data cleaning, since the signature protection mechanisms in Recovery-mode are more difficult to bypass.

Another common problem is hanging on the MI logo after firmware, which may indicate a conflict of versions of the underlying Android system (for example, switching from Android 13 to Android 11), in which case re-flashing with the fastboot -w (wipe) command helps, which is guaranteed to clean all partitions.

If your computer stops seeing your device in Fastboot mode, try replacing it. USB-cable, switch port on motherboard (use ports) USB 2.0) or reinstall drivers in Device Manager by manually selecting the Android Bootloader Interface model.
