How to bring back the old MIUI to Xiaomi: a complete guide with risks and solutions

You've upgraded your firmware on Xiaomi, Redmi or Poco, but the new MIUI version is worse than the old one? Is the battery going down faster, are there lags, or are favorite features missing? A rollback to the previous firmware is a real solution, but with pitfalls. In this article, we'll take all the official and informal ways to bring back the old version, assess the risks, and give checklists for a safe downgrade.

It’s important to understand that Xiaomi doesn’t always support one-click firmware rollbacks. In some cases, you’ll need to unlock the bootloader, work with Fastboot, or even lose data. We’ve compiled current techniques for 2026, including bypassing the restrictions on models with Anti-Rollback. If your smartphone is released after 2020, read the section on downgrade locking carefully.

Before you start, answer 3 questions:

1. Do you have a backup copy of the data?
2. Do you know the current MIUI and smartphone model (e.g. Redmi Note 11 Pro 5G)?
3. Are you ready for a possible loss of warranty when unlocking the bootloader?

1.Why you can't just "roll back the update" as you would on Windows

Unlike computer OSes, Xiaomi mobile firmware does not support the "cancel update" function.

• 🔒 Anti-Rollback protection: Starting with MIUI 10, many models block rollback to older versions by changing the anti partition in the device's memory.Trying to get around this can lead to a "brick" (completely inoperable) smartphone.
• 📦 Changes in memory: New versions MIUI System, vendor, and product partitions are often redistributed. Old firmware may not fit into updated partitions.
• 🔑 Lock bootloader: On all modern Xiaomi bootloader is locked by default. To install the old firmware it must be unlocked, which resets the device to factory settings.

The good news is that for most models before 2021 (such as the Mi 9, Redmi Note 8 Pro), the rollback is possible without serious manipulation, but owners of Xiaomi 12/13, Redmi Note 12 or Poco F5 will have to work hard.

2.Official method: rollback via Recovery (only for selected models)

The safest method is to use the built-in Recovery menu, but it only works if:

• 📱 Your model supports firmware installation via Recovery (list below).
• 🔄 You are going to go back to the version that was installed earlier (not any old version!).
• 🔓 The bootloader is not blocked (on new models it is blocked after the update).

List of models with recoil support via Recovery (relevant to MIUI 14):

Instructions:

1. Download the desired version of MIUI from the official Xiaomi website (choose Recovery ROM).
2. Rename the file to update.zip and place it in the root of internal memory.
3. Turn off your smartphone and press Power + Volume Up to log in to Recovery.
4. Select Install update.zip to System.

Download the correct version of Recovery ROM

Rename the file to update.zip

Charge your phone at least 60%

Disable signature verification (if you have an option)

-->

⚠️ Note: If after installation the smartphone stuck on the logo MI If it's 10 minutes or more, don't panic. Give it 30 minutes. If the screen is out and it's not on, try clamping the Power for 20 seconds.

3. Universal method: rollback via Fastboot (with unlocking the bootloader)

This works on 90% of Xiaomi models, but requires unlocking the bootloader.The process erases all data, so be sure to backup!

Step 1. Unlock the bootloader:

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Enable OEM Unlock and USB Debugging in Settings → Additional → For Developers.
3. Link your Mi Account to your device: Settings → Xiaomi Account → Mi Unlock status.
4. Download Mi Unlock Tool, log in to your account and follow the instructions.

Step 2. Install the old firmware via Fastboot:

1. Download Fastboot ROM for your model with Xiaomi Firmware Updater.
2. Unpack the archive in the platform-tools folder (from Android SDK).
3. Connect your phone in Fastboot mode (press Power + Volume Down).
4. Launch the file. flash_all.bat (Windows or run the command: fastboot flash all

⚠️ Note: On models with Anti-Rollback (e.g. Xiaomi) 11T, Redmi K40) Recoiling on old firmware via Fastboot can lead to a permanent lock (hard brick.

4. Anti-Rollback bypass: how to roll back on locked models

If your smartphone is equipped with anti-Rollback protection (the list of models here), a standard rollback will lead to an anti version down error.

• 🔧 Partial Downgrade: Install the oldest version possible that does not trigger Anti-Rollback. for example, for the Redmi Note 10 Pro with the MIUI 14 can roll back to MIUI 13.0.4.0, but not lower.
• 🛠️ Modified firmware: Use custom builds (e.g. from Xiaomi.eu) where protection is disabled.Risk: loss of official updates and possible bugs.

Instructions for partial downgrade:

1. Find the latest version on Xiaomi Firmware Updater before the current one (for example, if you have MIUI 14.0.3.0, look for 14.0.2.0).
2. Download Fastboot ROM Follow the instructions in the section. 3, But before the firmware edit the file. flash_all.bat:

@echo off


fastboot flash anti anti.img




fastboot flash --disable-verity --disable-verification vbmeta vbmeta.img




Fastboot flash... (no other instructions changed)

These lines disable the Anti-Rollback and vbmeta checker, but don't guarantee 100% success. On some models (e.g. Xiaomi 12 Pro), this can lead to a download cycle.

adb shell getprop ro.boot.anti

If the value is above 3, a recoil is almost impossible without the risk of a “brick".-->

5. rollback without data loss: method through ADB Sideload

If you don't want to lose data, you can try installing the old firmware through ADB Sideload in Recovery mode, which only works on some models and requires:

• 🔌 Connections to PCs with installed ADB Tools.
• 📄 Firmware in Recovery format ROM (not Fastboot!).
• 🔓 Unlocked loader (on new models).

Step-by-step:

1. Download Recovery ROM and rename it to update.zip.
2. Download to Recovery (Power + Volume Up).
3. Select Connect with MiAssistant (on some firmwares – ADB Sideload).
4. On PC, run the command: adb sideload update.zip

It takes 5-15 minutes, and if you get an E:footer is wrong, it means that the firmware is incompatible with your model or damaged.

💡

ADB Sideload is the only method of rollback without data loss, but it only works on firmware without Anti-Rollback and with the bootloader unlocked.

6 Risks and how to minimize them

Firmware rollback is not a harmless operation, but here are the main risks and ways to avoid them:

Checklist before rollback:

Make a backup on a PC or cloud

Check out the Anti-Rollback model and version

Download the firmware from an official source

Charge your phone to 80%+

Prepare a USB cable (preferably original)

-->

If after rollback the smartphone does not turn on:

1. Try to hold the Power + Volume Up for 30 seconds.
2. Connect to charging for 1 hour (sometimes helps with a discharged battery).
3. If the screen is black, use the EDL Mode Disclosure Instruction.

7.Recoilback alternatives: how to improve new firmware

If the risks of rollbacks scare you, try these ways first:

• 🔄 Settings reset: Sometimes lags and bugs go away after resetting to factory settings (Settings) → The phone. → Resetting settings).
• 🔧 Shutdown MIUI Optimization: In Developer Mode (Settings) → Additionally. → For developers, disable the option MIUI Optimization. It'll speed up animations and reduce lags.
• 📵 Restriction of background activity: C Settings → Annexes → Permits → Autostart Disable Autorun of Unnecessary Applications.
• 🔋 Battery calibration: Discharge the phone to 0%, charge to 100% without interruption, repeat 2-3 times.

If the problem is lack of features (for example, missing Second Space or Game Turbo), check:

• Region settings: Some features are only available in China or India (changed through Settings → Additional → Region).
• Hidden menus: for example, Game Turbo can be in Settings → Special features → Game Speed Booster.
