Updating software is a process that smartphone users Xiaomi perceive ambiguously. On the one hand, these are new functions and security fixes, on the other hand, there is a risk of the device becoming unstable or removing familiar features. Sometimes after installing a new version MIUI or HyperOS the phone starts to work incorrectly, quickly discharges or freezes. In such situations, the only way out is to return to the previous version of the system.
However, the rollback process is not as simple as the usual installation of updates. Manufacturers deliberately limit the ability to downgrade for security reasons so that users do not install vulnerable versions of software. However, there are proven methods to restore your device to an earlier state. You will need patience, careful adherence to instructions, and an understanding of the risks associated with data loss.
Before taking drastic action, you need to understand the types of rollbacks. You can try to remove the latest update through the settings if it was received over the air quite recently. If this option is not available, you will have to resort to a complete flashing of the device and clearing the memory. It is important to understand that version rollback almost always entails a complete data reset, so preparation is a critical step.
Preparing the device and backing up data
The most important step before any intervention in system files is saving personal information. When you roll back the firmware to Xiaomi the internal drives of the device will be completely formatted. This means that all photos, contacts, messages and installed applications will be permanently deleted. Ignoring this step may lead to the loss of valuable data that cannot be restored.
Use the system’s built-in tools or cloud services to create a backup. The most reliable way is to use Mi Cloud or synchronize with your account Google. You can also connect your smartphone to your computer via a USB cable and manually copy folders with media files to your hard drive. Make sure that the device's battery charge is at least 60% so that the process is not interrupted due to discharge.
⚠️ Attention: The firmware rollback process erases all data from the internal storage. Make sure that you have saved important files to external media or cloud storage before starting the procedure.
In addition to the data, you need to prepare the firmware files themselves. You will need to download the exact version of the system you want to revert to. You can find them on official forums or specialized resources, such as miui.com or XiaomiFirmwareUpdater. It is important to download exactly the version that was installed previously, or any older one that is compatible with your model. The wrong firmware can turn your phone into a “brick.”
☑️ Preparing for a rollback
Rollback method through settings (for recent updates)
If the update was recently installed and the device is running through a package update manager, the system may offer a built-in function to remove the update. This method is the least risky, as it does not require connecting to a computer and using complex utilities. However, it is only available for a short period of time after installation and does not work on all versions MIUI.
To check for this feature, go to the settings menu. Open the section About the phone and click on the system version icon. A menu with three dots will appear in the upper right corner of the screen. If the function is available, there will be an option “Uninstall update”. By clicking on it, the system will ask for confirmation and after a reboot it will return the previous version of the software.
In cases where the item is missing, this means that the window for rolling back is closed or the update was installed through third-party methods. Then you will have to use more complex methods associated with the Recovery or Fastbootmode. Do not try to search for hidden menus using engineering codes if you are not sure of their purpose, as this can lead to unpredictable malfunctions in the operation of the radio module.
If the “Uninstall update” item is inactive, try clearing the data of the “Component Update” application in the application settings, but this rarely helps in new versions of the shell.
Rolling back through Recovery mode using ZIP archive
The classic method of returning to an old firmware version involves using the stock recovery mode. To do this, you will need a firmware file in the .zipformat that matches your model and region. It is critical that the version you install is older than the current one, but belongs to the same branch type (for example, you cannot downgrade from Global Stable to China Developer without unlocking the bootloader).
Copy the downloaded archive to the root directory of the smartphone's internal memory. Do not place the file in any folders, it should be kept separately. After that, turn off the device and enter the mode Recovery, holding down the power and volume up buttons at the same time. In the menu that appears, select a language (usually English or Chinese is available) and find the item Install or "Install".
⚠️ Attention: If the system displays the error “Can't verify update” or “Zip signature verification failed,” this means that the rollback is blocked at the bootloader level. In this case, you will need to unlock Bootloader through the official Mi Unlock utility.
Select the firmware file from the list and confirm installation. The process will take a few minutes, after which the phone will prompt you to reboot. If the rollback is successful, the device will boot with an older version of the system. Otherwise, if you see an error, you will have to go to the method using a computer and Fastboot mode, which gives more access rights to system partitions.
Why does the signature verification error occur?
Android security system verifies the digital signature of the file. If you try to install a version older than the current one without special permissions, the bootloader blocks the installation, considering it potentially dangerous for data security.
Full rollback via Fastboot mode and computer
The most reliable way to roll back the update to Xiaomi is to use the mode Fastboot and the Mi Flash Tool app on the computer. This method allows you to completely rewrite the system partitions of the device, ignoring the restrictions imposed by the standard bootloader when installed via Recovery. However, to use it, your smartphone's bootloader must be unlocked. First, download and install the drivers on your computer. You will also need a utility
First, download and install the drivers ADB And Fastboot to your computer. You will also need a utility MiFlash, which can be found on the official MIUI forum. Unpack the downloaded firmware (it must be in format .tgz, not .zip) to the root of drive C so that the path to the files does not contain Cyrillic characters or spaces. This is a common cause of errors during firmware.
Put your smartphone into Fastboot mode by turning it off and holding down the power and volume down buttons. Connect the device to the PC with a cable. Launch Mi Flash, click the Refresh button for the app to detect your phone. At the bottom of the window, select the option clean all (clear all), which ensures that all data is deleted and the old version is installed correctly. Pressing the Flash button will start the process, which may take from 5 to 15 minutes.
| Installation mode | PC required | Unlock bootloader | Data saving |
|---|---|---|---|
| Settings systems | No | Not required | Possible |
| Recovery (ZIP) | No | Often required | No |
| Fastboot (Mi Flash) | Yes | Required | No |
Using Fastboot mode is the only guaranteed way to roll back to any previous version, but requires mandatory unlocking of the bootloader.
Problems with the bootloader and anti-rollback protection
Modern smartphones Xiaomi equipped with an anti-rollback mechanism known as Anti-Rollback. This protection prevents the installation of older versions of the bootloader or certain system partitions to avoid vulnerabilities. If you try to flash a device with a higher anti-rollback index to a version with a lower index, the phone may stop turning on.
Before downloading the firmware, carefully study its index. It is usually indicated in the file name or in the description on the aggregator site. If the current version has an index of 4, and you try to install a version with an index of 3, the process will fail or brick the device. In such cases, the only way out is to find a version with the same or higher index, but an earlier build date, which is extremely rare.
It is also worth considering the bootloader status. On devices with a locked bootloader (Locked Bootloader) rollback options are severely limited. You can only install official global firmware, the version of which is approved by the activation server. Any attempts to install custom builds or regional versions will be blocked. Unlocking the bootloader is officially possible through the service miui.com/unlock, but requires waiting from 7 to 168 hours.
Recovery after an unsuccessful rollback
If something went wrong during the rollback process and the device froze on the logo or went into an endless reboot (bootloop), do not panic. In most cases, the problem can be solved by re-entering the mode Recovery and performing a data reset (Wipe Data). Sometimes the system cannot boot due to a conflict between files of the old and new versions, and a complete cleanup resolves this conflict.
In more complex situations, when the phone does not respond to buttons and does not enter recovery modes, you will need to use the mode EDL (Emergency Download Mode). This is a deep service mode that allows you to flash a device even with a completely damaged bootloader. However, entering this mode on modern models often requires an authorized Mi account or a special test cable, which makes the procedure available mainly in service centers.
⚠️ Attention: The Recovery and Fastboot menu interfaces may differ depending on the MIUI version and device region. If you are not sure of your actions, it is better to contact a specialist so as not to lose the warranty.
After successfully restoring the device, do not rush to immediately restore all data from the backup copy. First, use your phone in basic mode for a few hours to ensure system, connectivity, and touch screen stability. Only after making sure that the rollback was successful and there are no hardware failures can you begin setting up and returning applications.
After rolling back the firmware, it is recommended not to restore applications in batches from the backup immediately. Install them again from the Play Market store to avoid transferring system errors or cache that caused problems.
Frequently asked questions about firmware rollback
Is it possible to roll back an update without losing data?
In the vast majority of cases, rolling back the Android version or MIUI shell requires a complete data reset (Wipe Data). This is due to the fact that the structures of databases and system files often change in new versions, and the old system will not be able to correctly read the data created by the new one. The only exception is the “Delete update” function in the settings, which rarely works.
What to do if the phone says “Update package is invalid”?
This error means that the firmware file is damaged, is not suitable for your model, or the rollback attempt is blocked by security policy. Try downloading the file again from another source, making sure that it is intended specifically for your model code (for example, M2101K6G). If the problem persists, you will need to unlock the bootloader.
Will the bootloader unlock status be reset after a rollback?
No, the bootloader unlock status (Unlocked) is saved in non-volatile memory and is not reset when flashing or rolling back the system version. However, if you lock the bootloader back after installing unofficial firmware, the device may not boot.
Is it dangerous to install global firmware instead of Chinese firmware during a rollback?
Changing the region (for example, from China to Global) during a rollback is only possible with an unlocked bootloader. This is not dangerous for the hardware, but will require complete data cleaning. Please note that global firmware may lack some functions present in Chinese versions, and vice versa.
How long does the rollback process via Fastboot take?
The firmware process itself via the Mi Flash app usually takes from 300 to 600 seconds. However, the total time of the procedure, including preparing files, installing drivers, unlocking the bootloader (if waiting is required) and initially setting up the system, can take from several hours to several days.
