Modern updates to the MIUI or HyperOS operating system often come with interface changes that may be unusual for long-time brand users. Sometimes the new version contains software bugs that reduce device autonomy or cause unstable applications. In such situations, the smartphone owner faces the question of how to return the gadget to work and restore the familiar environment.
The procedure for returning to the previous version of the operating system, known as downgrade, is technically possible, but requires strict adherence to security algorithms. Unlike a simple “over-the-air” update, a system rollback on Xiaomi often comes with risks associated with the company’s security policy. Starting with MIUI 12.5, a direct downgrade without unlocking the bootloader on global versions is often impossible, making preparation for the process critical.
Before you start taking action, you need to realize that rolling back a version is not a routine operation, but an interference with the structure of system partitions, which requires a stable connection to the computer, the original cable and a full backup of data, since in 99% of cases all information from the device will be irretrievably deleted during the formatting process.
Risks and limitations of the system rollback procedure
The main obstacle for users wanting to install old firmware is the Anti-Rollback protection mechanism, a technology introduced by Xiaomi to prevent installation of outdated versions of software that may contain known security vulnerabilities. If a device activates a high security index, trying to download the old version can lead to a “brick” state, where the smartphone will no longer respond to any commands.
Another critical issue is the status of the bootloader: On Locked Bootloader devices, the system checks the digital signature of the package being installed. If you try to install the global firmware on top of the Chinese or older version on top of the new one without the appropriate rights, the process will be interrupted initially. Unlocking the bootloader, in turn, leads to a complete data reset and may temporarily restrict the operation of some banking applications.
⚠️ Warning: Attempting to firmware a device with an active Anti-Rollback index of an older version can lead to irreversible software damage that cannot be repaired at home.
It is also important to consider regional features of firmware: Global and Chinese versions have different partition structures; trying to cross-regional rollback (e.g., from Global to China) without completely rewiring memory requires advanced skills and the use of specialized software such as the MiFlash Tool in Clean All mode.
Preparing a smartphone and computer for a downgrade
The success of the operation depends on the quality of the preparation, the first step is to find and download the firmware archive that you plan to install_recovery_ or in.tgz format for firmware through a computer, you can download current and archival versions on official resources or trusted portals, such as: MIUI bootloader.
After downloading the file, you need to check its integrity. The archive damaged during download can lead to verification error during installation. Also make sure that the charge of your smartphone is at least 60%, or better fully charge the device before you start manipulating. Unstable power at the critical moment of writing system files is fatal to the device.
☑️ Checking rollback readiness
For users planning to use the computer method, it is mandatory to install Qualcomm HS-USB QDLoader or MediaTek USB VCOM drivers (depending on the processor), as well as Mi Unlock utilities to unlock the bootloader, if necessary. Without properly installed drivers, the computer will not be able to see the smartphone in Fastboot firmware mode.
Method One: Local Update through Recovery
This method is the least risky and suitable for cases where the difference between versions is small, and the bootloader is unlocked or the region's security policy allows local installation.
To start, place the downloaded firmware file (update.zip) in the root directory of the smartphone’s internal memory. Don’t put the file in folders, use the root to make it easier for the system to find it. Then go to Settings → About phone and click on the MIUI version. In the window that opens, click on the three dots in the upper right corner and select “Select firmware file”.
If the system finds the file and allows you to start installing it, the process will go automatically, but if you see a message saying "File failed to check" or "Version too old," then the built-in protection mechanism blocks rollback, in which case move on to more sophisticated methods.
💡
If the Select Firmware File menu doesn’t appear, try clicking the MIUI version number in the About Phone menu 7 times quickly to activate the additional developer features.
Method Two: Using the Mi Flash Tool and Fastboot Mode
The most reliable way to roll back the system on Xiaomi is to use a computer and the Xiaomi Mi Flash Tool utility. This method requires you to transfer the smartphone to Fastboot mode, which is carried out simultaneously by pressing the volume down button and the power button when the device is turned off. The screen of the smartphone should light up with an image of a rabbit repairing an android.
Run the Mi Flash Tool on your computer and connect the device with a cable. If the drivers are installed correctly, your device with the serial number will appear in the list. Press the Select button and specify the path to the unpacked firmware folder (.tgz format). folder should not contain Cyrillic symbols in the way, it is better to place it in the root of the disk, for example, C:\MIUI_ROM\.
At the bottom of the utility window, you'll see three options: To do a clean rollback, you'll need to select the Clean All option, which forcefully formats all memory partitions and installs the new (old) system clean. The Clean All and Lock option also reflashes the device but re-locks the bootloader, which can cause problems if you change the firmware region (for example, from China to Global).
| Firmware mode | Data retention | Locking the loader | Recommendation |
|---|---|---|---|
| Update | Preserve. | No change. | Only to update to a newer version |
| Clean All | Complete removal | No change. | Recommended for downgrade and region change |
| Clean All and Lock | Complete removal | Locks it down. | Only to return to factory condition (caution!) |
⚠️ Warning: When selecting Clear All and Lock mode on a device with a modified firmware region (e.g. Global on China), the smartphone can go into the eternal logo or lock. Use this mode only if the firmware region coincides with the region of the device.
What if Mi Flash flashes all except data storage?
Solving common mistakes and problems
Downgrade users often encounter the error “Can’t verify update” (Can’t verify update), which is the standard MIUI security response to an attempt to install an older version, and it is almost impossible to get around this limitation without unlocking the bootloader, so the only solution is to use the computer and the Fastboot mode described above.
Another common problem is sticking on the MIUI logo after installation, which occurs when data from an older version of the system conflicts with a new (actually older) version of the kernel, 90% of the time this is solved by performing a full Wipe Data reset via the Recovery menu. To log into Recovery, press the power button and turn up the volume.
If the device stopped responding to buttons and did not turn on, it may have fallen into EDL (Emergency Download Mode) mode. In this case, the screen remains black, but in Windows Device Manager, the smartphone is defined as Qualcomm HS-USB QDLoader 9008. To get out of this state, it often helps long (about 15-20 seconds) hold of the power button, or requires an authorized Mi Account to firmware through EDL.
💡
The most common reason for a botched rollback is to ignore the requirement to clean up your data completely. When you change versions of Android or MIUI, always do Wipe Data to avoid file conflicts.
