How to Install Old Firmware on Xiaomi: A Complete Guide to Risks and Solutions

Returning to the previous firmware version on Xiaomi devices is a challenge that users face after unsuccessful updates. The new version of MIUI can bring bugs, performance declines or incompatibility with traditional applications. However, rolling back firmware is a risky process: it can lead to a breeze (complete failure) of the device, data loss or locking up the bootloader. In this article, we will examine all the safe ways of downgrade, from official methods to alternative solutions for locked bootloaders.

It is important to understand that Xiaomi does not support firmware rollback through standard settings. All manipulations with the system are performed at the user's risk. However, with the right approach - with backup, unlocked bootloader and verified firmware files - the chances of success are up to 90%. We will look at options for devices with unlocked and locked bootloader, as well as the nuances of working with Redmi, Poco and Black Shark models.

Why do users go back to the old firmware?

The main reasons for downgrading firmware on Xiaomi are related to the problems that arise after the update:

• 🐢 Slowdown: New versions MIUI Often optimized for flagship models, which leads to lags on budget devices (for example, Redmi Note 8 or Poco). X3 NFC).
• 🔋 Increased battery consumption: Background processes in fresh assemblies can reduce battery life by 15–30%.
• 🚫 Application incompatibility: Some programs (such as banking or anti-cheat games) refuse to work on new versions of Android.
• 🎨 Interface changes: Users get used to a specific design MIUI, a sudden change (as in the transition from the MIUI 12 on MIUI 13) cause discomfort.
• 🔒 Blocking features: New firmware may disappear useful features, such as Game Turbo or settings DC Dimming.

According to surveys on the 4PDA and XDA Developers forums, about 25% of Xiaomi users have tried to roll back firmware at least once, and 60% of them have experienced difficulties due to a blocked bootloader or mischosen version of MIUI.

Preparing for Downgrade: What to Do Before Starting

Before you start rolling back the firmware, follow the mandatory steps, which can lead to data loss or the inability to restore the device.

Make a backup copy of the data (photos, contacts, messages)

Check the status of the bootloader (unlocked/locked)

Download the correct firmware version for your model

Charge your phone at least 60%

Install ADB/Fastboot drivers on PC

-->

Backup is a critical step. Use:

• 📱 Local Copy: Transfer files to a PC or external drive through MTP (data-transmitting).
• ☁️ Cloud services: Mi Cloud, Google Drive or Telegram (for small files).
• 🔄 Third-party utilities: Titanium Backup (requires root) or Swift Backup to save applications and their data.

To check the status of the loader:

1. Turn off the phone.
2. Press Volume Down + Power to enter Fastboot.
3. Connect the device to the PC and enter the command: fastboot oem device-info If the answer has the line Device unlocked: true - the bootloader is unlocked.

⚠️ Note: On devices with a locked bootloader (Redmi Note 10 Pro, Xiaomi) 11T and newer) the rollback of firmware is possible only through the official MIUI bootloader or service center. Self-attempts lead to blocking IMEI.

How to install old firmware on Xiaomi

The choice of method depends on the status of the bootloader and the device model. Let's consider three main options:

We will discuss each method in detail.

Method 1: Installation via Recovery (for unlocked bootloader)

This is suitable for custom Recovery (e.g. TWRP) or stockware devices if the firmware is officially signed, with the main advantage being simplicity and minimal risk.

Steps:

1. Download the archive with firmware in.zip format for your model from the Xiaomi Firmware Updater website or the official MIUI portal.
2. Move the file to the root directory of the phone’s internal memory (not to folders!).
3. Turn off the device and press Volume Up + Power to enter Recovery.
4. In TWRP, select Install → specify the downloaded file → swipe for confirmation.
5. After installation, run Wipe Cache/Dalvik and restart.

⚠️ Warning: If after the reboot the phone is stuck on the logo MI, Try re-entering Recovery and doing Wipe Data, which will delete all user data, but often solves the problem.

💡

If Recovery doesn't have ZIP installation, you have stock Recovery without manual firmware, and then use Fastboot.

Method 2: Installation via Fastboot (Universal Method)

The most reliable, but also the most risky method, requires an unlocked bootloader and command line skills, suitable for all Xiaomi models, including new ones.

Instructions:

1. Download Fastboot firmware (a file with the extension.tgz or.zip) for your model. Pay attention to the region (Global, China, EEA).
2. Unpack the archive in a folder on your PC (e.g., C:\MIUI\).
3. Turn off the phone and press Volume Down + Power to log into the Fastboot.
4. Connect the device to the PC and check the connection command: fastboot devices If the device is determined (the serial number appears), continue.
5. Run the firmware script: fastboot flash all or (for new models): fastboot update name file.zip

Critical: Don’t interrupt the firmware process, even if it’s 99% frozen. On Xiaomi 12/13 and Redmi K50, it can take up to 10-15 minutes.

Method 3: Official Downgrade via MIUI bootloader

For devices with a locked bootloader (for example, Redmi Note 11 Pro+ 5G or Xiaomi 12 Lite), Xiaomi sometimes provides the ability to roll back through proprietary software.

Algorithm:

1. Go to Settings → About the phone → System update.
2. Tap 10 times on the version of MIUI to activate the extended mode.
3. Return to the update menu and click on the three dots in the upper right corner → Select the service pack.
4. Specify the path to the downloaded firmware (should be an official and stable version).
5. Confirm the installation and wait for the reboot.

If the option to choose the service pack is absent, then your model does not support this method. Alternatively, you can contact the Xiaomi service center with a request for a rollback (the service is paid, the cost is from 1,500 to 3,000 rubles).

💡

Official downgrades are only possible within one version of Android, for example, with MIUI 14 on MIUI 13 (both on Android 13), but not with Android 13 on Android 12.

Common mistakes and their solutions

When you roll back firmware, users often face typical problems.

• 🔴 Anti-rollback error: When you try to install firmware older than the one you installed earlier, find a version with the same or newer anti-rollback index. How do you check the anti-rollback index, V13.0.4.0.SKUCNXM_20220412.0000.00_11.0_cn_1234567890, where 1234567890 — The new firmware must have an index no lower than the current one.
• 🔴 Hanging on the logo MI: The reason is that the kernel or modules are incompatible. Solution: Repeat the firmware with full Wipe Data.
• 🔴 Invalid sparse file error: The firmware file problem: Solution: Re-download the archive and check the checksum (MD5).
• 🔴 Loss of loss IMEI: It's relevant for devices with a locked bootloader. QCN-file (requires root or service center).

If the NFC module, camera or fingerprint sensor stops working after a downgrade, the driver incompatibility is likely the problem.

• Fastboot flashing with clean all check in the Mi Flash Tool.
• Installation of a custom core (e.g., FrancoKernel for Poco F3).
