How to roll back Xiaomi firmware to the previous version: the full guide

Xiaomi smartphone owners often face a situation where, after a scheduled or forced update of the operating system, the device begins to work unstable, the battery can discharge faster, interface artifacts appear, and some familiar applications cease to function correctly, in which case the only effective solution is to roll back Xiaomi firmware to an earlier, stable build.

Downgrade requires care and preparation, as errors at any stage can lead to data loss or software failures. However, with accurate instructions and understanding the differences between Recovery and Fastboot methods, the user can independently return the gadget to work without going to the service center.

In this article, we will go through all the steps of preparation, method selection and direct flashing. It is important to understand that returning to the old version of software is not just a file replacement, but a complex procedure that affects system partitions. We will look at the nuances of working with MIUI and HyperOS, so you can choose the best way to solve the problem.

Reasons for returning to the old version

The need to roll back the system is not only due to obvious bugs. Often users notice a decrease in autonomy or overheating of the case after upgrading to a new version of MIUI. Developers can optimize the code for new features, inadvertently causing increased power consumption on older models of devices.

Another common cause is loss of functionality, such as changing the algorithms of the camera or removing popular shell features in new builds, which becomes a critical factor for photographers or those who are used to a particular workflow, requiring immediate intervention.

• 📉 Dramatic drop in battery life for no apparent reason.
• 📱 The appearance of system errors, freezes and spontaneous reboots.
• 🔒 Blocking important functions or removing familiar system tools.
• 🚫 Incompatibility of mission-critical work applications with the new OS version.

Also worth mentioning are situations where a new firmware contains security errors or malfunctions with certain carriers, in which case a downgrade is a temporary but necessary solution until a fix is released.

⚠️ Warning: Before any manipulations, make sure that the battery is at least 60% charged. Interrupting the firmware process at low charge can lead to irreversible consequences.

It's important to realize that each model responds to updates differently, and what works consistently on a flagship can cause problems on a budget device due to hardware differences.

Preparation for the procedure: backup and tools

The most important step is preparation. The rollback procedure almost always involves completely removing the data from the internal drive, so backing up is not a recommendation, but a requirement.

Use MIUI built-in backup tools or third-party tools like Mi PC Suite. Save contacts, photos, documents, and application settings to external media or cloud storage. Make sure the copy is complete and recoverable.

For the job you will need a high-quality USB-Cheap cables can only charge, but not transmit data at the desired speed, which will lead to firmware errors.

You also need to install ADB and Fastboot drivers on your computer, and without them, you can't interact properly with your phone in bootloader mode, and you can download them as part of Platform Tools from the official Android developer site.

Choice of method: Recovery or Fastboot

There are two main ways to return the old version of the system: through the built-in Recovery menu and through the Fastboot mode, the method choice depends on your current situation and the type of firmware available.

Recovery is a good way to go if you want to roll back to a neighboring version (like V12 to V11 of the same branch) and you have a Recovery version of the firmware. It's a simpler way, not requiring complex software on a PC, but it has version limitations.

Fastboot is a universal method that allows you to install any version of software, even older than the current one, and it requires you to connect to a computer and use a special utility called the Mi Flash Tool, which is the method most often used for a full downgrade.

Choose a method based on your skills and available resources. If you're a beginner and the situation is not critical, try Recovery. If you want a guaranteed result and a rollback to a much older version, choose Fastboot.

Method 1: Recovery Menu Recoil

This method is suitable if the bootloader is unlocked or if the firmware version allows you to flash without locking. You will need a firmware file in.zip format, which you need to place in the root of internal memory or on the back of the back. SD-map.

Turn your phone to Recovery mode. Turn off the device and press the power and volume buttons at the same time. When the logo appears, release the buttons. From the menu, select the language (usually English or Chinese) and go to Install Update.

Find the selected firmware file and confirm the installation. The system will warn you that all data will be deleted. Agree and wait until the process is over. After the restart, you will get a clean system of the previous version.

Importantly, this method does not always allow you to roll back through one or two versions. MIUI's security policy may prohibit installing significantly older builds on top of new ones through a standard menu.

The most reliable way that is guaranteed to work is to download the firmware in.tgz format for your model. Unpack the archive on your computer, and there will be a folder with many files and scripts inside.

Launch the Mi Flash Tool on behalf of the administrator. Put your smartphone in Fastboot mode by pressing the power and volume button when the device is off. Connect your phone to your PC with a cable.

fastboot devices

This command in the command line will help check if the computer sees the device. If the serial number is displayed in response, the communication is set correctly. In Mi Flash, press the Refresh button and your device should appear in the list.

At the bottom of the window, select firmware mode. Make sure to choose Clean all or Clean all and lock for a clean rollback. Be careful: choosing the lock option can lead to problems if you change the firmware region.

💡

Use it. USB-A port built into the computer motherboard (back of the system unit), rather than ports on the front panel or hubs, will provide stable power and data transfer.

Press the Flash button and wait for completion. The process can take anywhere from 5 to 15 minutes. Do not turn off the cable or touch the phone until a successful completion message appears.

⚠️ Note: When using the Fastboot method with the "Clean all and lock" option, make sure the firmware matches the region of the device. Installing global firmware on a Chinese machine with the bootloader lock will lead to a brick.

Typical errors and their solution

Users often experience errors during downgrades, and one of the most common is Error: Anti-rollback, a security mechanism that prevents users from installing a version of software with a lower security index than the current one.

If you encounter such a bug, you can't get around it with software. The anti-rollback index is written into a protected partition of memory and can't be lowered, so you'll have to wait for a new stable version to come out, or look for workarounds if they exist for a particular model.

• ❌ Mistake. 0x80004005: Problem with access rights or antivirus. Try running Mi Flash on behalf of the administrator and temporarily disable protection.
• ❌ Phone Undetectable: Install Qualcomm or MediaTek drivers manually through Device Manager.
• ❌ Logo getting stuck: Try making Wipe Data in Recovery or reflashing with a full cleanup.

Another problem may be regional mismatch: China firmware (CN) and Global have different memory sections, and trying to install one on top of the other without fully cleaning and re-marking can result in a sensor or camera that is not working.

💡

The main rule of successful rollback is the exact match of the device model and the downloaded firmware, using files from another model is guaranteed to bring the gadget down.

Don’t ignore error logs if they appear in Mi Flash. Take a screenshot of the error code and look for its decryption in specialized forums, as the codes may vary from version to version.
