Modern updates to the MIUI shell or the new HyperOS often bring not only new features, but also unforeseen bugs that can significantly reduce the comfort of using a smartphone. Users face rapid battery discharge, overheating of the case or unstable operation of communication modules after installing a new version of the software. In such situations, the only effective solution is to return to the previous, more stable build of the operating system.
The process of rollback version, or downgrade, on Xiaomi devices is technically possible, but requires strict adherence to the sequence of actions to avoid locking the device. It's important to understand that standard About Phone menus don't do this, because security prevents you from installing an older version on top of a new one, USB-cable and follow the instructions for the selected recovery method.
Before you take action, you need to understand the risks and prepare all the tools. Downgrade is always accompanied by a complete deletion of all user data, so backing up critical information is a must. Below we will discuss in detail the two main ways of returning: through the Recovery menu and a deeper method through the Fastboot mode.
Preparation for the procedure of rollback of the MIUI version
The foundation of successful flashing is the quality of the workplace and the device itself. You will need a stable Internet connection to download files and workable. USB-cable, preferably original or certified to avoid communication breakdowns at a critical time, also make sure that the battery charge of the smartphone is at least 60%, as the process can take a long time.
The next step is to find and download the correct firmware archive. You need Recovery ROM (for the method through the update menu) or Fastboot ROM (for the method through the computer), and the version should be strictly lower than the one installed now.
Remember to activate USB debugging and get extended rights if the chosen method requires it. Fastboot often requires the installed ADB and Fastboot drivers on your computer, as well as an unlocked bootloader, whose status can be checked in the engineering menu.
☑️ Checklist of preparations
Recovery Menu (No PC)
This method is considered the most secure for beginners, as it does not require deep intervention in system partitions through the computer. The essence of the method is to rename the firmware file and start its installation through the standard update menu, but there is an important nuance: the system will not just roll back without resetting data.
To implement this plan, you need to put the downloaded Recovery ROM zip archive in the root of the smartphone’s internal memory. After that, in the software version selection menu, you need to click on the current version several times to open the hidden menu where the firmware file is selected. If the system detects a compatibility error, you will need to rename the file to update.zip and use a special code in the call menu to activate additional functions.
In some cases, the standard version checker locks the installation, requiring manual intervention, and then activating additional developer functions by entering special commands in the Phone application helps, which allows you to bypass the signature verification and start the installation of older software with a complete memory cleanup.
Secret code for activating functions
Use Fastboot Mode and Mi Flash Tool
If the soft methods don't work, Fastboot mode comes to the rescue, which allows you to reflash the device at a low level. This method requires a Windows computer, a Mi Flash Tool installed, and an unlocked bootloader. The firmware archive in this case should be in.tgz format and unpacked into the root folder without Russian characters on the way.
After transferring the smartphone to Fastboot mode (clutching the volume key down and connecting the cable), you need to start the program on the PC. In the utility interface, the path to the firmware folder is selected, and at the bottom of the window, clean all mode is necessarily selected, which guarantees complete data cleaning and installation of a clean system.
The firmware process takes 300 to 600 seconds, after which the device automatically restarts. It is important not to interrupt the connection or touch the cable until the logo appears. MI In case of errors in the program logs, such as error: not enough space, you should check the free space on the system disk or integrity. USB-port.
💡
Use it. USB-port 2.0 on the back of the motherboard, as ports 3.0/3.1 On some older motherboards, drivers may crash when firmware is running.
Solving Common Mistakes in Downgrade
When returning an old version of software, users often face technical hurdles that are easily solved with knowledge. One of the most common problems is the message “Can’t verify update”, which occurs when you try to install global firmware on top of Chinese or vice versa, in which case only a complete Fastboot flashing with a preliminary change of account region helps.
Another common situation is the endless reboot after installation, which can mean the residual files of the old system conflict with the new one, and the solution is to enter Recovery mode and execute the Wipe Data command, which will return the phone to the factory settings.
Also worth mentioning is the "Anti-rollback" error, which is a protective mechanism against rollbacks on vulnerable versions. If you try to install a firmware with a lower protection index than the current one, the device may lock permanently. Always check the anti-rollback version before starting the procedure.
| Type of error | Probable cause | Decision-making |
|---|---|---|
| Can't verify update | Inconsistency of region or type of firmware | Use Fastboot or change your account region |
| Bootloop (Cycle) | Data conflict after downhrade | Make Wipe Data in the Recovery Menu |
| Mistake 7 in Recovery | Wrong file name or path | Rename update.zip and put it in the root |
| Anti-rollback error | Attempting to roll back below safe level | Switch the current stable version through Fastboot |
💡
The Anti-rollback error is critical: trying to bypass it can turn a smartphone into a “brick” without the possibility of recovery by software methods.
Cleaning up data and first start-up of the system
Once the old firmware version is successfully installed, the initial setup phase begins, because downgrade involves formatting a data partition, the phone will greet you with a language selection screen, and at this point it is important to take your time and carefully follow all the steps, especially when connecting to Wi-Fi and logging into a Google account.
The system can request confirmation of the device owner if a device search was previously enabled. Enter the password from your Google or Mi Account account that was used before the reset. Ignoring this step will result in the device being blocked by a theft protection feature.
After you load your desktop, you should immediately disable automatic system updates to avoid re-installing the problematic version. To do this, go to the settings, find the MIUI version and select “Disable Auto Update” from the menu or delete the service pack through the application menu.
⚠️ Warning: After the first turn on, the phone may work slowly during the 15-20 This is normal, because the system optimizes the cache and indexes the files in the background.
Precautions and data security
Working with system partitions always carries certain risks, and minimizing human errors is the main task of the user. Before starting any manipulations, make sure that you have access to the Internet and the ability to quickly find drivers or utilities if something goes wrong.
Keep backups of important documents and photos not only on cloud services, but also on a physical medium, such as a computer or an external hard drive. The cloud can sync errors or delete files when versions conflict, so a local copy is your last line of defense.
If you are unsure of your abilities or are afraid of losing data, it is better to contact an authorized service center. Professional masters have access to paid tools for repair and can restore the device even in difficult cases, while maintaining warranty obligations.
⚠️ Note: Using modified bootloaders or custom recaps may permanently void the manufacturer’s warranty on your device.
💡
Always double backup: one to the cloud, the other to your computer, as cloud synchronization after a downgrade may not work properly.
