Updating MIUI firmware on Xiaomi Redmi smartphones is a key process for improving performance, fixing bugs and getting new features. However, the wrong actions can lead to data loss, device freeze or even complete failure. In this article, we will discuss all the current ways of updating – from standard OTA to manual firmware via Fastboot – and also tell you how to avoid typical errors and what to do if something goes wrong.
It is important to understand that the upgrade process depends on the Redmi model (e.g. Redmi Note 12 Pro+ or Redmi 10C), the current version of MIUI (global, Chinese, European) and the status of the bootloader. Some devices require pre-unlocking the bootloader, and for others, a few clicks in the menu are enough. We will describe each step in detail so that you can choose the best method for your case.
1.Preparation for the update: what to do before the start
Before you start the update, follow the mandatory preparatory steps, which minimizes risks and simplifies the process:
- 📱 Check the model and version MIUI: Go to Settings. → Write down a model (e.g. Redmi Note 11 Pro) 5G) and the current version of the firmware (for example, MIUI 14.0.5 Global).
- 🔋 Charge the battery to at least 60%.When upgrading via Recovery or Fastboot, 100% is recommended, as the process can take up to 30 minutes.
- 📡 Connect to stable Wi-Fi. Update via mobile Internet may be interrupted due to unstable signal.
- 📁 Create a backup: Use Settings → Additionally. → Backup and reset or third-party applications like Swift Backup.
Pay special attention to unlocking the bootloader if you plan to manually firmware. On new Redmi models (released after 2021), the bootloader is locked by default.
- Link your Mi Account to your device.
- Wait 7-15 days after submitting your application to the Mi Unlock Tool.
- Use official software from Xiaomi to unlock.
⚠️ Attention: Unlocking the bootloader resets all data on the device! Also, it can deprive you of warranty if the smartphone is purchased in official stores (for example, Mi Store or Messenger).
Method 1: Automatic Air Update (OTA)
The easiest and safest method is to upgrade by air (Over-The-Air, OTA). It is suitable for most users and does not require technical skills. OTA-updates gradually, so the new version may not appear immediately after the official announcement.
To check for updates:
- Open Settings → About the phone → System update.
- Click on the three-dot icon in the upper right corner and select Update Package (if available).
- If an update is found, click Download and wait for the download to complete.
- After downloading, select Install Now or Install at night (if you do not want to interrupt the smartphone).
If the update is not available, the following reasons are possible:
- 🌍 Your version. MIUI supportive OTA (For example, Chinese firmware on a global device).
- 🔄 Xiaomi has suspended the distribution of the update due to bugs (so it was with the company) MIUI 14 for Redmi Note 10 Pro in early 2023).
- 📵 Device modified (installed) TWRP, root-rights).
💡
If the update doesn’t come long, try changing the region in Settings → Additional → Region to India or Russia. Sometimes this speeds up the OTA.
| The benefits of OTA | OTA's shortcomings |
|---|---|
| ✅ Does not require technical knowledge | ❌ Updates come with a delay |
| ✅ All data and settings are stored | ❌ Not always available for custom firmware |
| ✅ Minimum risk of error | ❌ It is impossible to regress to the previous version. |
Method 2: Manual update via Recovery
If OTA is not available or you want to install a specific version of MIUI, you can use manual updates via Recovery.This method is suitable for official firmware and does not require unlocking the bootloader, but will require downloading the update file manually.
Instructions:
- Download the correct firmware version for your model from the official Xiaomi website. Pay attention to the region (Global, EEA, China) and the code name of the device (for example, vili for Redmi Note 11 Pro+ 5G).
- Move the firmware file (usually with the.zip extension) to the root folder of the smartphone's internal memory. Don't unpack the archive!
- Go to Settings → About Phone → System Update, click on the three-point icon and select Select Update File.
- Select the downloaded file and confirm the installation. The device will reboot to Recovery and start the process.
If the installation does not start after restarting, you can start it manually:
- Turn off your smartphone.
- Press Volume Up + Power before the Mi logo appears.
- From the Recovery menu, select Install update.zip to System (use volume buttons for navigation and power button for confirmation).
⚠️ Note: If you install firmware for another region (e.g. Chinese on a global device), some features such as Google Services or support may be missing after the update. LTE-ranges of your operator.

4. Method 3: Fastboot Firmware (for power users)
Fastboot is the most reliable way to flash Redmi if other options don't work.
- 🔄 Recovery of the device after failure (brick).
- 📥 Install an older version MIUI (downgrade).
- 🔓 Firmware on a locked bootloader (if Xiaomi is allowed).
To run through Fastboot, you will need:
- 💻 Computer with drivers installed ADB/Fastboot.
- 📋 Official firmware in.tgz or.zip format (downloaded from Xiaomi website).
- 🔧 The Mi Flash Tool (you can download it here).
- 🔑 Unlocked loader (if required).
Step-by-step:
- Unpack the firmware archive in a folder on your computer (e.g., C:\MIUI\).
- Turn off your smartphone and put it in Fastboot mode: press Volume down + Power before the hare appears in the hat-eared.
- Connect the device to the computer through USB-cable (preferably original).
- Launch the Mi Flash Tool, press Select and specify the path to the firmware folder.
- At the bottom of the program, select firmware mode: Clean all - complete cleaning (recommended in case of failures); Clean all and lock - cleaning + locking the bootloader (only for official firmware); Save user data - saving data (not always stable).
Flash
Fastboot firmware using Clean all and lock mode can block the bootloader back if it has been unlocked, making it impossible to install custom firmware in the future without re-unblocking.

5.Typical Update Errors and How to Fix Them
Even if you follow the instructions, you can get errors, and let's look at the most common ones and how to solve them.
| Mistake. | Reason. | Decision |
|---|---|---|
| Couldn't verify update | A damaged firmware file or model mismatch | Download the file again and check the model compliance |
| Error 7 in TWRP | Incompatibility with current version of MIUI | Install an intermediate version or use Fastboot |
| Hanging on the Mi logo after the update | Failed firmware or module conflict | Reset via Recovery or go through Fastboot |
| Mi Flash: Flash is not done | Problems with drivers or cable | Check the connection, try another port/cable |
If the smartphone stopped turning on (brick) after the update, try the following steps:
- Press Volume Up + Power for 10-15 seconds for forced reboot.
- If it doesn’t work, plug it into charging for 30 minutes – sometimes it helps with a discharged battery.
- Use Fastboot to re-rout (see Method 3).
- In the extreme case, contact a service center (for example, Xiaomi Authorized Service).
Instructions for rollback via Fastboot:
- Download the desired version of the firmware from the official website.
- Unpack the archive and delete the file flash_all_lock.bat (if any, to avoid blocking the loader.
- Swipe your device through the Mi Flash Tool in Clean All mode.
- After the firmware, reset the settings to Recovery (Wipe data).
⚠️ Note: A rollback to a version older than the one installed on the device when you bought it could cause problems with the Widevine module (Netflix, Disney will not work)+ into HD-quality).
