How to roll back Xiaomi version: a guide to downgrad

Owners of Xiaomi, Redmi and Poco smartphones often face a situation when after an automatic update the system begins to work unstable, the battery runs out faster, there are strange interface bugs, and some familiar features disappear or change the logic of work, it is at such moments that there is an urgent need to roll back the version of the operating system MIUI or HyperOS to the previous stable state.

The process of returning to an old build, known as a downgrade, is technically more complicated than a regular upgrade. Xiaomi's default security system prevents installing an older version of software on top of a new one. This is done to protect against vulnerabilities that have been patched in recent patches. However, with the right sequence of actions and the right tools, you can get around these limitations.

In this article, we will discuss in detail all stages of preparation, the risks of data loss and how to restore the device to work. It is critical to understand that the forced installation of old firmware through Fastboot with an unlocked bootloader is the only guaranteed way to make a rollback without obtaining the status of “brick”.

Why do users want to go back to the old firmware?

Often, enthusiasts and ordinary users are trapped in new versions of Android. Xiaomi developers regularly release updates that theoretically should improve performance. In practice, on specific models, especially the budget segment, new shells can cause overheating of the processor or lags in animations.

Another common reason is the removal of advertising services or a change in privacy policies: new MIUI builds are becoming more aggressive, with privacy-centric users forced to look for ways to return to versions where these features worked differently or were not available.

Also worth mentioning is the problem of third-party compatibility: some banking applications or specialized software may not work properly on beta versions of HyperOS. In such cases, rollback is not a whim, but a necessity for full use of the smartphone for work purposes.

• 📉 Deterioration of battery life after system update.
• 🐛 Errors in the operation of communication modules and GPS.
• 🔒 Change of security policy that blocks installation of desired applications.
• 📱 Unstable operation of the touchscreen or proximity sensor in the new version.

⚠️ Note: When you roll back, you potentially open the device to known security vulnerabilities. Make sure the reason for the return does outweigh the risks of using software with security holes.

And the subjective factor is also there: the interface changes, icons move, and the logic of the menu becomes confusing; for many users, the familiar environment is more important than new but useless features; the desire to regain comfort is a legitimate reason for complex technical manipulation.

Risk assessment and data preparation before the procedure

Before you start active actions, you need to understand the main feature of the downgrade process: unlike a regular update, the rollback version does not save user data. The system requires a complete cleaning of the /data partition to avoid conflicts of file structures of different versions of Android.

This means that all photos, contacts, instant messaging and apps installed will be permanently deleted. Even if you use Xiaomi Cloud, it is better to create a local copy on your computer.

Pay special attention to two-factor authentication. If you reset your phone, you will need access to a SIM card or backup codes to log into your Google and Mi accounts. Make sure the phone number is active and the backup codes are stored in a secure location outside the phone.

Another important aspect is the availability of the original cable: cheap cables from the nearest store often do not withstand long-term transmission of large amounts of data in Fastboot mode.

Unlocking the loader: a mandatory stage

Without an unlocked bootloader, you can’t install an older firmware version using official methods. Xiaomi blocks this feature at the server level. You’ll need a Mi Account account tied to the device and a special Mi Unlock Tool app on your computer.

The process is not instantaneous. Once you apply in Settings → About Phone → MIUI version (a few quick clicks on the build number), you will have to wait 3 to 7 days, which is the time the company needs to check the activity of the account and prevent mass resale of devices.

It is important to understand that once the bootloader is unlocked, some features of the phone will become unavailable, such as banking applications that use Google Pay (now Google Wallet) with high security requirements, if you do not use additional methods of hiding root rights, and the possibility of using Widevine L1 will disappear, which will reduce the quality of HD streaming on some services.

There is a myth that you can unlock a bootloader faster through paid services. There are methods of bypassing waiting, but they require deep knowledge and often involve the risk of getting caught by fraudsters. The official path, although long, guarantees the preservation of warranty (formally) and stability of work.

Finding and selecting the right version of the firmware

Finding the right version of the software is not always trivial. Xiaomi’s official website rarely stores archives of old builds in the public domain. You will have to use specialized aggregators such as Xiaomi Firmware Updater or XDA Developers.

If you have a global version (Global), you can't run a Chinese or Indian build without changing the region of the device, which can cause LTE/5G in your region to fail.

It is also critical to check the firmware type. To roll back through Fastboot, we need a file with the.tgz extension, not.zip. Zip files are designed to be updated through the recovery menu and often don't allow you to downgrade even with an unlocked bootloader.

Make sure the firmware version of Android you want to roll back to is the same or lower than the current one, but doesn't require you to go through major versions of Android with a change in partition structure if you're not sure of your actions. For example, switching from Android 13 to Android 11 may not be possible without completely rewiring the drive.

Instructions: rollback via Fastboot and Mi Flash Tool

This is the most reliable and recommended method. It requires a Windows computer, an ADB/Fastboot driver installed, and a Mi Flash Tool utility. First, unpack the downloaded firmware archive into the root of the C disk so that the path is short and Cyrillic-free.

Put your smartphone in Fastboot mode. To do this, turn off the device completely, then press the volume button and connect the cable to the computer. FASTBOOT It's a hare fixing an android, if the device is identified in the Device Manager as QHSUSB_BULK, drivers installed incorrectly.

Launch the Mi Flash Tool on behalf of the administrator. Press the Refresh button so that the program sees your smartphone. On the way to the firmware, select a previously unpacked folder. At the bottom of the window, select Clean All mode. This is a prerequisite for a downgrade.

Press the Flash button and wait for the process to be completed.The green progress bar will reach the end and the phone will automatically reboot.The first download can take up to 10-15 minutes, don't be alarmed if the Xiaomi logo hangs for a long time.

• 🔌 Connect your phone with the original cable directly to your PC motherboard (not through hubs).
• 💻 Close all programs that use USB, including antiviruses and synchronizers.
• 🔋 Make sure that the battery does not fall below 50% during the process.
• 🚫 Do not turn off the cable or press buttons until the desktop appears.

⚠️ Warning: Selecting the "Clean all and lock" option will lock the bootloader back, only if you are fully confident in the compatibility of the firmware region and the device region.

Alternative methods and recovery from errors

There is a method of rollback through Recovery using a computer and ADB commands, but it does not work on all versions of MIUI. If you have a global stable firmware installed, the system can prevent the installation of an older archive, giving an error "Can't verify update."

Sometimes, after a downgrade, users are faced with the problem of endless restart (bootloop). If the bootloader remains unlocked, try logging back into the Fastboot and reflashing the device by selecting the clean all option again.

If the phone has stopped responding to buttons and the computer, but is defined as a Qualcomm device, you can try using EDL (Emergency Download Mode) mode, however, entering this mode on new models often requires an authorized Mi Account, making this method available only in service centers.

💡

Save screenshots of important settings before resetting. After rolling back the version, many menu items can change location, and you will forget which options were exposed earlier.

Remember that after a successful rollback and the first setup, the system will start offering updates again. To avoid automatically installing the new version, turn off the Internet immediately after the reset, go to the settings and prevent auto-update, or use special applications to block system updates.

💡

The only safe way to roll back is an unlocked bootloader, Fastboot (.tgz) firmware, and Clean All mode. All other methods have a high risk of failure.
