Modern Xiaomi smartphones receive regular updates to the operating system, which are designed to improve the stability of work and add new features. However, in practice, it often happens that after installing a fresh version of MIUI or a new HyperOS, the device begins to work unstable, quickly discharge or lose important functions.
The process of downgrading the firmware version, or downgrade, is a technically complex operation that requires careful attention and understanding of risks. Unlike a regular update that takes place in automatic mode, system rollback often requires the use of a computer, special utilities and an unlocked bootloader. Before starting any manipulation of system files, you need to be clearly aware of what you are doing and prepare all the necessary tools in advance.
In this detailed guide, we will discuss all the available ways to return to the old version of the software, from simple methods through the recovery menu to advanced methods using the Fastboot mode. We will also focus on preparing the device to avoid losing personal data and turning your smartphone into a “brick.” If you encounter bugs after an update, this article will help you regain the comfort of using the gadget.
Preparation for rollback procedure
The first and most critical step is to save all user data. Because the rollback procedure often involves completely clearing internal memory, all photos, contacts, correspondence and files will be permanently deleted. Backup is a must-do step, ignoring which can lead to the loss of important information forever. Use Google Drive, Mi Cloud or create a local copy on your computer.
The second step is to find and download the correct firmware file. You need to find the version of the system you want to return to, and it must be newer than the one you have installed now (in some cases), or it must correspond to the region of the device. Firmware files for Xiaomi usually have the extension.zip for the Recovery method or.tgz for the Fastboot method. You can download them from official aggregator sites or developer forums.
⚠️ Warning: Make sure that the battery charge of the smartphone is at least 60-70%. Interrupting the flashing process due to battery discharge can lead to irreversible damage to the software and the inability to turn on the device.
You will also need quality. USB-cable and installed drivers ADB Windows users often require additional Qualcomm or MediaTek drivers, which can be found as part of the Mi Flash Tool or download separately. Without the right drivers, the computer simply won’t see the smartphone in the right mode.
☑️ Checklist of preparations
Recovery Menu (No PC)
The most affordable way to downgrade a firmware version doesn’t require a computer or complex utilities, but it has its limitations. This method only works if you want to roll back one version or if the current version of the system allows you to install an older version through the regular update menu. First, place the downloaded firmware file (update.zip) in the root of the device’s internal memory.
Then go to recovery mode. To do this, turn off your smartphone and press the combination of the buttons Volume up + Power before the Mi logo appears. In the menu that opens, select the language (usually English and Chinese), and then click on Install update.zip or “Install update package.” If the firmware file is compatible, the system will prompt you to start installing.
However, users often encounter an error called “Can’t verify update” or “Package is broken,” which means that the built-in security system blocks the installation of the old version on top of the new one, in which case the standard method will not work, and you will have to resort to more radical measures using the computer, and it is worth noting that this method does not require unlocking the bootloader, which is its main advantage.
- 📱 Put the file down. update.zip root.
- 🔌 Reboot to Recovery Mode (Loudness Up). + Nutrition).
- ✅ Select the update installation and confirm the action.
- ⏳ Wait for the process to end and automatic reboot.
💡
If the system says that the file is corrupt, try renaming the firmware file to “update.zip” (if it’s called otherwise) or using a data cleanup method, but remember that this will delete all files.
Use of Mi Flash Tool and Fastboot Mode
The most reliable and versatile way to roll back an update is to use the official Mi Flash Tool utility on your computer, which allows you to flash the device cleanly, changing any version to any one (subject to regionality rules), but it requires an unlocked Bootloader bootloader. If the bootloader is blocked, the utility will give an error and refuse to start the firmware process.
To start, move your smartphone to Fastboot mode. This is done by turning off the device and then pressing the Volume down buttons. + Power. You'll see a picture of a hare repairing an android, signaling a successful transition to mode. USB-Cable and run the Mi Flash Tool on behalf of the administrator.
In the program interface, click the Refresh button to let your computer discover the connected device. Then select the path to the folder with the unpacked firmware (the images file must lie inside the folder). It is imperative to choose the correct firmware mode at the bottom of the window: for full rollback and data cleanup, choose Clean all. Save user data mode when rolling back version often leads to errors and cyclical reboots.
| Firmware mode | Data retention | Requirements | Risk of error |
|---|---|---|---|
| Clean all | No (full reset) | Unlocked BL | Low. |
| Save user data | Yes. | Unlocked BL | High on rollback |
| Clean all + lock | No. | Unlocked BL | Middle (region) |

Bootloader problems and regional limitations
One of the main obstacles when rolling back firmware on Xiaomi devices is the status of the bootloader. Global versions of devices are often sold with the Bootloader blocked, which is done for security reasons. Unlock requires a wait of 7 to 168 hours after submitting an application through the Mi Unlock app, as well as having a Mi Account with a phone number tied.
The second important thing is regional binding, because you can't, without additional manipulation, flash a global firmware version onto a device that's designed for the Chinese market, and vice versa, if the regions don't match, and if you try to do that through the Mi Flash Tool, you'll get the error "Missmatching image and device," in which case only a complete firmware reflash helps with cleaning all partitions.
There is also the concept of “anti-rollback” (Anti-Rollback), introduced by the manufacturer to protect against installing vulnerable versions of the software. if your current firmware index is higher than the one you want to go to (for example, the anti-rollback index is higher than the one you want to go to, ARB 4 against 4. ARB 3), then installing the older version is physically impossible and may result in the device being locked. ARB before the beginning of the procedure.
⚠️ Warning: Trying to flash firmware with a lower Anti-Rollback index than the current one can lead to hard-bricking of the device, which cannot be restored by software methods without contacting the service center.
Recoil from Xiaomi ADB/Fastboot Tools
For advanced users who don’t want to use the heavyweight Mi Flash GUI, there is an alternative in the form of scripts and console utilities such as Xiaomi ADB/Fastboot Tools. This method allows you to control the firmware process through the command line, which gives you more flexible control over the process and the ability to see detailed error logs in real time.
The main advantage of this method is the ability to force partitions to be cleaned or selectively firmware individual modules of the system if standard methods do not work. However, using the command line requires high concentration and accuracy of command input. One typo in the syntax of the fastboot command can lead to unpredictable results.
Before using this method, make sure that the platform is installed on the computer. SDK Platform-Tools. Commands are entered in the terminal or command line after connecting the device in Fastboot mode. A typical command to start the firmware looks like fastboot. flash_all clean, but specific parameters may vary depending on the firmware file structure.
fastboot getvar all
fastboot flash boot boot.img
fastboot flash system system.img
fastboot reboot💡
Using ADB/Fastboot tools gives you more control, but requires strong command line skills and an understanding of the structure of Android partitions.
Frequent mistakes and ways to solve them
In the rollback process, users often encounter various errors that can stop the process. One of the most common is the signature verification error, which occurs when you try to install the official firmware on a device with the bootloader unlocked, but the signature files do not match. The solution is to use the Clean all method in the Mi Flash Tool or flash through Recovery with a pre-clearance data.
Another common problem is hanging on the Mi or Android logo after installation is complete, which can mean that the old and new system files are in conflict, so you need to re-enter Recovery mode and run Wipe Data and then Wipe Cache, and only after the partitions are completely cleaned, the old system can start correctly.
If the device goes into an endless bootloop and doesn't respond to the buttons, the system partition may have been damaged, and in this case, only re-routing the Fastboot with full formatting will help. SIM-cards and memory cards before turning on, as the system may try to read configuration files from them.
