Modern Xiaomi, Redmi and POCO smartphones regularly receive operating system updates that are designed to improve security and add new features. However, in practice, it often happens that after installing a fresh version of MIUI or switching to Android 13/14, the device begins to work unstable. Users may experience a rapid battery drain, overheating of the processor or the disappearance of important functions that worked in the previous build.
There is a natural desire to return everything as it was, but the usual system means this option is not usually provided, you will not help standard resetting settings or cleaning the cache, because they do not affect the system partition, where the version of the operating system itself is stored. rollback is possible only by completely reflashing the device to an earlier version of the software, cleaning all the data, a complex process that requires care, preparation of special tools and understanding the risks associated with loss of warranty or locking the device.
Before you start taking action, you need to realize that the rollback procedure is not a regular function of the manufacturer. Xiaomi does not provide the “Return to the previous version” button in the update menu, as this can create security vulnerabilities. Therefore, all the methods described below involve working with system files at a deep level. If you are not sure of your abilities, you should wait for the patch to come out or contact an authorized service center.
Risk analysis and preparation for the system downgrade
The first step before any software manipulation is to understand the Anti-Rollback protection architecture. This is a security mechanism built into the Xiaomi device bootloader that prohibits installing an older version of the firmware if the protection index in the new version is higher. Trying to bypass this restriction or ignoring the index check can lead to a "brick" state where the phone will cease to respond to any commands. You can check the current index in Fastboot mode by looking at the Anti string at the top of the screen or in the firmware logs.
The second critical aspect is the total loss of user data. The rollback process is always accompanied by formatting the internal drive, which means that your photos, contacts, instant messengers and installed applications will be permanently deleted. Even if you back up through the Mi Cloud or Google cloud, some data, such as banking app settings or game cache, may not be restored correctly after you change the Android version.
⚠️ Note: Installing firmware with a lower Anti-Rollback index than installed in the bootloader can lead to irreversible locking of the device (Hard Brick), the recovery of which is possible only through paid services of programmers.
Global versions (Global) often have stricter restrictions on flashing than Chinese ones (China). If you try to install global firmware over Chinese or vice versa without first unlocking the bootloader and changing the region, the process will end in error. Make sure the firmware type (CN, Global, EEA, RU) matches the current one or you are ready to perform a full reset with unlock.
To successfully perform the procedure, you will need a stable Internet connection, serviceable. USB-cable (preferably original) and Windows computer using virtual machines or unstable ports USB The battery charge of the smartphone should be at least 60% so that the device does not turn off during the recording process.
Choosing the right firmware version for rollback
Finding the right software is the foundation of a successful rollback. You need to find an official firmware version that is lower than the current one, but it must be compatible with your specific model code name. For example, for the Xiaomi Mi 9T, the code name is davinci, and confusion with versions for davinciin (Indian version) is unacceptable. You can download current and archival versions from proven aggregators such as XiaomiFirmware or Xiaomi.eu.
It is important to distinguish between firmware types: Recovery and Fastboot. To roll back without unlocking the bootloader, it is theoretically possible to use the Recovery version through the update menu, but only if the new firmware version is higher than the installed one, which contradicts the rollback task. So in 99% of cases you will need a Fastboot firmware that has the.tgz extension (archive), unlike the Recovery version with the.zip extension. It is Fastboot mode that allows you to force the older system image into the phone memory.
- 📁 File extension: Make sure that the downloaded file has a.tgz extension, not a.zip extension, as the PC method requires an archive with a partition image.
- 🌍 Regionality: The firmware must be strictly in line with the region of your current system (Global for Global, China for China), or there will be a compatibility error.
- 🔢 Android Version: Check Not Just the Version MIUI (For example, 12.5), but also the basic version of Android (10, 11, 12), as the rollback of Android also has its limitations.
- 📅 Release Date: Select the version released before the installation date of your current update to ensure you roll back the changes.
When downloading, pay attention to version stability. It is better to choose labeled as Stable, avoiding beta versions (Beta) or development builds (Developer), unless you are a tester. Beta versions can contain bugs that will complicate the rollback process or lead to unstable system operation after installation. Always check the checksum (MD5 or SHA1) of the downloaded file to ensure the integrity of the download.
Where to look for archive firmware?
Recoiling with Fastboot and Mi Flash Tool
The most reliable and versatile way to return a previous version of the system is to use the Mi Flash Tool utility on your computer, which requires an unlocked bootloader (in most cases), but it gives you complete control over the partition writing process. First, you need to install Qualcomm or MediaTek drivers (depending on your smartphone’s processor) and ADB/Fastboot Drivers to the computer. Without the drivers installed correctly, the computer will not see the phone in the right mode.
After the software is prepared, the smartphone is converted to Fastboot mode. To do this, turn off the device completely, then press the volume button and connect it. USB-And you'll see a picture of a hare repairing an android on the screen, and it'll say, FASTBOOT. Unpack the downloaded firmware archive in the root of the C disk or in any short-path folder that does not contain Cyrillic characters to avoid path-reading errors.
☑️ Checklist before firmware
Launch Mi Flash Tool on behalf of the administrator. Press Refresh to detect the connected device. In the address field, specify the path to the folder with the unpacked firmware. The critical point is to select the firmware mode at the bottom of the window. To clean rollback, select the Clean all option that completely erases data and re-marks partitions. The Clean all and lock option will lock the bootloader back, which is only safe if you put the original global firmware on the global version of the device.
Press the Flash button and wait until the process is complete. The status window will display the progress bar and the current operation (e.g. programming: abl, programming: system). The entire process takes 5 to 15 minutes. Once completed, the phone will automatically restart. The first boot after rollback can last up to 10 minutes - this is normal, since the system optimizes applications and creates new configuration files.
| Parameter | Description | Recommendation |
|---|---|---|
| Clean all mode | Complete data cleanup without blocking the loader | Choose for tests and custom firmware |
| Clean all and lock mode | Clearing data and blocking the loader | Only to return the runoff before selling |
| Save user data mode | Attempt to save data (not recommended) | High risk of errors when rolling back versions |
| Portal of connection | USB 2.0 / 3.0 | Use USB 2.0 ports for compatibility |
Recoil without PC: using Recovery and triple tap
There is a non-computer rollback method that relies on the hidden Recovery mode function, but it does not work on all models and versions of MIUI. The essence of the method is to manually select a firmware file in internal storage and activate the hidden menu through multiple clicks. However, it is worth noting that officially this method is intended to update to a newer version, and the system can block the installation of older software, giving an error "Can't update verify".
To try this method, download Recovery firmware (.zip file) and rename it to update.zip. Place the file in the root of the phone's internal memory (not in the folder, but in the root). Go to Settings menu → About phone → System update. Click on the tri-point in the corner and select "Select firmware file." Specify your update.zip file.
Once you select the file, you'll start checking, and if the system detects that the version is older, it will give you a warning, and then you'll quickly press 10 times the MIUI logo in the center of the screen, and if you're lucky and the model supports that, you'll have an additional menu with a choice of installation mode. Choose Wipe Data + Clean All. If the menu doesn't show up, you'll have Recovery-level downgrade protection on your device, and you'll have to use the method from your PC.
⚠️ Note: Attempting to install firmware through Recovery can result in a Bootloop if the versions of the base partitions (modem, tz) are incompatible.Be prepared to need to flash through Fastboot.
This is less reliable than using the Mi Flash Tool, since Recovery mode has limited functionality and does not always correctly handle version conflicts. In addition, when rolling back through Recovery, it is often impossible to bypass digital signature verification if the device bootloader is locked, so this method can only be considered as a temporary solution or experiment if there is no computer at hand.
Specificity of rollback on models with a blocked loader
Owners of Locked Bootloader devices are in the most vulnerable position. Xiaomi's official policy prohibits installing older firmware versions on devices with a locked bootloader unless the security index allows it. Trying to flash the old version through Fastboot without unlocking will lead to an Unlocked bootloader error is required or similar.
The only legal way to roll back in this situation is to wait for a new stable version of the firmware, which can be installed on top of the current one, or contact an authorized service center. Service centers have access to special authorization tools that allow you to sew the device around standard checks, but this service is paid and requires proof of ownership of the device.
There are informal methods of bypassing locks through vulnerabilities in older processor bootloaders (e.g., EDL mode with an authorized account), but they require deep technical knowledge and are often associated with the risk of fraud when buying firmware accounts. Using such methods automatically removes the device from warranty. In addition, after 15 minutes of waiting in EDL mode (Qualcomm HS-USB QDLoader 9008), most modern models require an authorized Mi Account to continue the firmware.
If you plan to experiment with firmware frequently in the future, it is recommended to unlock the bootloader officially through the Mi Unlock site in advance.This will take 3 to 7 days to wait, but will give you full control of the device. Remember that unlocking the bootloader also leads to a complete data reset, so it is better to do this before you have problems with the update.

Save the screenshots. IMEI-In the event of a critical failure, this data may be required to restore the device to the service center or to uncouple from the Mi Account.
Possible errors and ways to eliminate them
In the rollback process, users often encounter various bugs, coded by the firmware utility or the phone itself. One of the most common bugs is Anti-rollback check failed. It means you're trying to install a firmware with a lower security index, and there's no solution to this bug, except to find a firmware version with the same or higher index but an earlier release date, which is almost impossible, and then you can't roll back.
Flash all except data storage is not supported or simply a device failure to respond to commands is often driver-related or USB-Try replacing the cable, switching to the port. USB 2.0 (black, not blue) on the computer motherboard (back of the system unit) and reinstall Qualcomm drivers. Sometimes it helps to run the command line or the program itself on behalf of the administrator.
If the phone went to Bootloop (cyclic reboot) after a botched pullback, don't panic.Try to enter Recovery mode (clamping the volume up and power button) and perform Wipe Data/Factory Reset.If that doesn't help, only Fastboot mode and a repeat firmware attempt, perhaps using the Clean all and lock option to reset all partition state flags.
⚠️ Note: If the phone has gone into mode EDL (screen black, Device Manager sees Qualcomm HS-USB QDLoader 9008) and you don't have an authorized account, self-recovery may not be possible.Do not try to disassemble the phone without experience, so as not to damage the plumes.
There are also regional compatibility errors, such as when trying to put Chinese firmware on a global device, in which case the Mi Flash Tool will give an ID verification error. To avoid this, always check the device code name and region. Using custom Recovery, such as TWRP, allows you to bypass some checks, but requires a pre-unlocked bootloader and adb command line skills.
💡
A successful rollback is possible only if three conditions are met: the coincidence of the firmware region, the presence of an unlocked bootloader (for the Fastboot method), and the absence of an Anti-Rollback lock.
