How to install the old version of MIUI on Xiaomi: Step-by-step analysis

Accidental upgrade to a new version of the operating system often comes as an unpleasant surprise for owners of Xiaomi smartphones. Instead of the expected performance gain, the user may face a quick battery drain, strange interface tanks or just get used to the old logic of the menu. It is at such moments that there is an urgent need to return everything as it was, but the standard settings menu does not provide such an opportunity.

Android’s downgrade is not just a file copy, but a complex technical operation that requires strict adherence to security algorithms. Unlike iOS, Android allows you to install an earlier version of the software, but only when you completely clean all user data to avoid software conflicts. Before you start active actions, you need to soberly assess the risks and prepare the device.

In this guide, we will discuss in detail two main methods of returning to the previous build: through the Recovery menu and using a computer in Fastboot mode. You will learn how to unlock the bootloader, where to take verified firmware files and how to avoid turning a smartphone into a “brick”.

Risks of rollback and device preparation

The first step is to understand that rolling back MIUI is a destructive operation. Xiaomi's security system blocks the ability to simply switch versions precisely to protect data integrity. If you try to roll over the old firmware on top of the new one without resetting, the device will go into an endless bootloop.

So the only way to go is with full Wipe Data, which means that all your contacts, photos, messages and settings will be permanently deleted. ⚠️ Before starting the procedure, be sure to create a full backup of important data in the cloud or on your computer, otherwise it will be impossible to restore the information after formatting.

It's also important to consider the state of the battery. The flashing process requires stable power, and if the charge drops below. 50-60%, The procedure may be interrupted at the most inopportune moment. USB-The cable is good and the computer port has no backups.

Another critical issue is regional compatibility: If you have a global version (Global), you can't just put a Chinese version (China) or an Indian version (India) without unlocking the bootloader. Trying cross-regional updates on a locked bootloader will result in a signature verification error.

Finding and Choosing the Right Version of the Firmware

Finding the right file is half the success. Xiaomi's official website doesn't keep archives of older versions open to users, so you'll have to use trusted third-party resources. You'll need a file with the.zip extension for Recovery or.tgz for Fastboot.

The key is the type of firmware. To roll back without using a computer and complex software, we will need Recovery ROM. This is a full system image that weighs between 2 and 4 GB. It is important that the version you want to install is really older than the current one installed on the phone.

You can check the current version by going to Settings → About Phone. Note the build number, for example, V14.0.3.0.TKGMIXM. This code encrypts the region and the device model. The file you want should have a smaller numerical index in the title.

• 📂 Recovery ROM: File format ZIP, Destined to be installed via the recovery menu or built-in updater.
• 💻 Fastboot ROM: File format TGZ, Requires a PC connection and the use of the Mi Flash Tool.
• 🌍 Regionality: Global firmware (Global) usually has labeling MIUI, Chinese — CN, Indian — IN.

When downloading files from unverified sources, always check the checksum (MD5 or SHA1) if provided by the author, which ensures that the file has not been corrupted during download or modified by third parties.

Method 1: Installation through the built-in update menu

The easiest way to do this is to use a built-in update mechanism, but on newer versions of MIUI, this feature is often hidden or limited. If your current version allows, you can try installing the archive manually.

First, copy the downloaded.zip file to the root of your smartphone's internal memory. Don't put it in folders, use the main storage space. Then go to the software update menu.

To activate the hidden file selection menu, you need to click several times on the current version of MIUI. Usually 7-10 quick clicks are enough until a pop-up with additional options appears.

When you have three dots in the corner of the screen, click on them and select "Choose update package." ZIP-The system will check the integrity of the file.

If the file version is newer than the current one, the installation will start immediately, if you try to roll back to the older version, the system will issue a warning, and in some cases, you will need confirmation through your Mi Account account, the password from which must be known.

Method 2: Recovery Mode (Clean Install)

If the built-in updater refuses to install the old version, you will have to use the recovery mode, which guarantees a clean installation, but requires an unlocked bootloader in most cases, especially when changing regions.

Rename the downloaded firmware file to update.zip to make it easier to search. Copy it into internal memory. Turn off the smartphone completely.

To enter Recovery mode, press the button combination. On most Xiaomi and Redmi models, this is the on and Volume Up + Power button. Hold them until the logo appears.

⚠️ Attention: In the Recovery menu, the touch screen is not working, the navigation is done with volume buttons (up/down), and the choice is with the power button.

In the menu that appears, select a language (usually English and Chinese), then search for Wipe Data and confirm the reset. This is a mandatory step for the old firmware to work correctly.

After cleaning, select Connect with MIAssistant (if you need a PC connection to transfer the file) or, if the file is already in memory, select Install Update (not available in all Recovery). ADB.

Method 3: Fastboot and Mi Flash flash flash flashing

The most reliable and versatile way to get around many software limitations is to use Fastboot mode. For this, you will need a Windows computer and the Mi Flash Tool utility.

Download and unpack the firmware archive (.tgz) on your computer. The path to the folder should be short and not contain Cyrillic, for example, C:\ROM\. There should be a script inside the folder. flash_all.bat or flash_all_except_storage.bat.

Put your smartphone in Fastboot mode. Connect the device to your PC by holding down the Volume Down button. The screen will show an image of a hare repairing an android, or the words FASTBOOT.

Launch the Mi Flash Tool on behalf of the administrator. Press the "Refresh" button to allow the program to detect your device (serial number will be displayed). If the device is not visible, check the Windows Device Manager for Android Bootloader Interface drivers.

Click "Select" and specify the folder with the unpacked firmware. At the bottom of the window, be sure to select the Clean all option. This is critical when rolling back versions.

💡

If the Mi Flash Tool gives an error "Flash All Except Data", try to switch to "Clean All". When rolling back the version, saving data is technically impossible due to differences in partition structure.

Press the flash button and wait until the process is over. Green "success" signifies successful completion. The smartphone automatically reboots, and the first download can take up to 10 minutes.

Solving Frequent Errors and Problems

During downgrade, users often encounter an error called "Can't verify update" or "Zip signature verification failed." This means that the security system blocks the installation. The solution is one - unlock the bootloader through the official Mi Unlock procedure.

Another common problem is the anti-rollback error, which has some models that physically prevents you from installing a version below a certain one (for example, you can’t roll back from Android 12 to Android 11 if the protection index has changed).

⚠️ Warning: Trying to bypass anti-Rollback protection on active index devices can cause the motherboard to fail completely (Hard Brick.

If the phone is in a bootloop, try logging into Recovery and making Wipe Data manually. If that doesn't work, just flashing through Fastboot with a full cleanup will help.

💡

The success of the MIUI version rollback is 90% dependent on the correct choice of firmware type (Recovery/Fastboot) and mandatory data reset before installation.

It is also worth remembering that after rolling back on very old versions, some modern applications (banking, instant messengers) may stop working due to the lack of support for older versions of Android or security certificates.
