How to safely roll back from Android 11 to Android 10 on Xiaomi smartphones

The rollback from Android 11 to Android 10 on Xiaomi devices is a procedure that can be necessary for various reasons, from unstable work of the new version to incompatibility with critical applications. However, this process is far from as simple as a conventional “over the air” update. Unlike installing fresh firmware, downgrade requires careful preparation, understanding of risks and strict adherence to instructions.

The main problem is that Xiaomi does not provide official tools for rolling back the Android version. This means that the user will have to manually unlock the bootloader, install custom or stock software via Fastboot or Recovery, and put up with potential data loss. Moreover, some models (for example, Mi 10, Redmi Note 9 Pro) after a downgrade may encounter errors in the Widevine module. L1, Which will lead to a loss of support. HD-content on Netflix or Disney+.

In this guide, we will look at all the steps of the process, from checking the compatibility of your device to the final setup after rollback, and focus on the risks that are often hidden in superficial instructions, as well as alternative methods if the standard method did not work.

Why do users want to return to Android 10?

The move to Android 11 isn’t always justified, especially when it comes to budget or outdated Xiaomi models, and these are the most common reasons why owners decide to roll back:

• 🐢 Performance: On weak chipsets (e.g. Snapdragon 660 or Helio) G80) Android 11 is noticeably slower due to increased memory and processor requirements. Lags when multitasking, slowing animations and long application loads are typical complaints.
• 🔋 Autonomy: Optimizing power consumption in the new version often leaves much to be desired. Many people note that after the upgrade, the smartphone discharges 15-20% faster under the same use cases.
• 📱 Application incompatibility: Some banking programs (e.g. SberBank Online, older version), anti-cheat games, or enterprise software may not work on Android 11 due to changes in the permission system.
• 🎯 Interface changes: Updated notification menu, media player management and navigation gestures MIUI 12.5+ Some people prefer the usual Android 10 with its classic design.
• 🔧 Errors and bugs: On some models (e.g. Poco) X3 NFC) After the update, there are problems with Bluetooth, accidental reboot or non-functional NFC.

It's important to understand that not all problems are solved by rollbacks, for example, if the bugs are related to hardware (for example, overheating the processor), then returning to the old firmware may not help. Before starting a downgrade, it's worth checking whether your problem is an isolated case - perhaps it can be fixed by resetting settings or disabling specific functions.

Preparing the device for rollback: what to do in advance

Downgrade firmware is an irreversible process that can lead to the loss of all data on the device. So the preparation should be as thorough as possible.

1. Backup. Use the built-in Backup tool in Settings → The phone. → Backup or third-party utilities like Swift Backup (requires root: 📁 Contacts, SMS and call log (export to.vcf and.xml). 📷 Photos and videos (copy to PC or cloud). 🔑 Passwords and application data (use Google Smart Lock or Bitwarden).

Check the model and firmware version

Settings → About the phone

• 📱 The exact name of the model (for example, Redmi Note) 9S, Not just the Note 9).
• 🔢 Current version MIUI (for example, MIUI 12.5.3 Global).
• 🔄 Firmware Region (Global, China, EEA etc.).
• Unlock the bootloader. Without this step, you can't install the old firmware. Note that unlocking erases all data and requires you to link your Mi Account to your device. More on this in the next section.
• Charge your smartphone to at least 60%. Interrupting the process due to battery discharge can turn the device into a brick.

Pay special attention to firmware choices. Not all versions of Android 10 are compatible with your model. For example, if you used MIUI Global, you can't install MIUI China, which will cause problems with Google services. Only use official firmware from the Xiaomi Firmware site or proven resources like Xiaomi Firmware Updater.

Unlocking the bootloader: a mandatory step before downgrade

The bootloader on Xiaomi smartphones is locked by default, a security measure that prevents unofficial software from being installed. To roll back on Android 10, it needs to be unlocked. The process takes 3 to 7 days and requires a Mi Account to be linked.

Here's the step-by-step instruction:

1. Link your Mi Account to your device: Go to Settings → Xiaomi account. Make sure your account is confirmed by email and phone. Enable data sync.

Launch the utility and log in.

under the same account as on the phone.

Fastboot

:

• Press Volume Down + Power before the Fastboot logo appears.

Once successfully unlocked, the bootloader will be open to install any firmware.

⚠️ Warning: Unlocking the bootloader resets the device to factory settings. All data, including photos, messages and apps, will be deleted.

If you already have a bootloader unlocked (for example, you have previously installed custom software), this step can be skipped. ADB:

In the answer, look for Device unlocked: true. If it's false, the bootloader is locked.

Selecting a firmware: which version of Android 10 to install

Not all Android 10 builds will work for your device, and a mistake in choosing can lead to a smartphone blink.

Where to download the firmware:

• 🌍 Official Xiaomi website: MIUI Downloads.Look for the Archive or Stable section marked Android 10.
• 🔗 Xiaomi Firmware Updater: Link. All firmware versions are collected here, including old ones.
• 💾 4PDA or XDA Developers: Modified firmware is often posted on forums, but its use is risky (viruses or unstable work are possible).

Critically, if your device originally came with Android 10 (like the Redmi Note 8 Pro), then a rollback to an earlier version of MIUI (like MIUI 12.5 to MIUI 11) can cause data loss in the /data partition due to a change in the encryption structure, in which case a complete reset will be required after installing the firmware.

Before downloading, check the hash amount of the file (usually listed on the site) to avoid installing corrupted firmware. Use utilities like 7-Zip (CRC shows) or certUtil-hashfile on Windows to check.

Step-by-step: how to roll back from Android 11 to Android 10

Once all the preparations are complete, you can start installing, and we'll look at two methods: through Fastboot (recommended) and through Recovery (for power users).

Method 1: Installation via Fastboot (most reliable)

This is a good way to do it for most Xiaomi models and is minimally risky.

• 🖥️ Windows computer 10/11 (For the Mi Flash Tool).
• 🔌 Cable USB (preferably original).
• 📁 Firmware in.tgz or.zip format for Fastboot.
• 🛠️ The Mi Flash Tool (you can download it here).

Steps:

1. Run the Mi Flash Tool on behalf of the administrator.
2. Select Clean All (Full Cleaning) or Clean All and Lock (Clean + Lock bootloader After Installation).

Once installed successfully, the device will automatically restart, and the first launch can take up to 15 minutes — that's normal.

Method 2: Installation with Recovery (alternative)

This method is suitable if you already have custom recovery (TWRP) installed or if the firmware supports installation via stock Recovery.The risks are higher, as errors may occur when unpacking the archive.

Steps:

1. Download the firmware in.zip format for Recovery.
2. Rename the file to update.zip and place it in the root of internal memory.
3. Boot in Recovery: Turn off your smartphone. Press Volume up + Power.

Install update.zip

⚠️ Note: If after installation via Recovery smartphone stuck on the logo MI After 20 minutes, you've had an error, so you'll have to reset the process via Fastboot or reset the settings via Wipe Data. TWRP.

What to do after rollback: setup and check the system

Successful installation of Android 10 is only half the battle, so now you need to make sure that the system is stable and restore the lost data.

1. First run: Select language and region. Connect to Wi-Fi (don't use mobile data to download updates!) Skip signing in to Google and Mi (please add them later if required).
2. Audit of substantive functions: 📞 Telephony: Make a test call and check the mobile Internet. 📶 Wi-Fi and Bluetooth: Connect to the network and pair the device (e.g. headphones). 🎮 Sensors: Test a gyroscope, accelerometer and fingerprint scanner. 🔊 Sound: Check the speakers and microphone.
3. Data recovery: Copy backups from your PC or cloud, install apps through Google Play, and restore contacts and SMS from previously saved files.

Security update

• Go to Settings → System → Software Update.
• Install the latest security patches (but don’t upgrade to Android 11!).

💡

If you lose photos or files after a rollback, check the /MIUI/backup/AllBackup folder on the internal drive. Sometimes backups are saved there automatically.

Common problems after rollback and their solutions

Even with a successful Android 10 installation, there may be problems, and here are the most common ones and how to fix them:

If none of the solutions worked, it may be the hardware (e.g., damaged memory) that is the problem, and you should contact Xiaomi’s service center.

Also worth mentioning is the loss of warranty: unlocking the bootloader and installing unofficial software will void warranty obligations. If your device is still warranty, weigh the pros and cons before rolling back.

💡

If after the rollback you notice that the smartphone began to warm up stronger or discharge faster, check the background processes in Settings → Battery → Battery use.
