How to Upgrade Xiaomi Properly: Secure Methods and Common Errors

Software updates on Xiaomi devices are not just a way to get new features; they are a critical process that affects the safety, performance and stability of a gadget. However, an incorrect update can lead to a “brick” (routine break), data loss or even a device failure. In this article, we will discuss all the current ways of updating, from standard OTA-apats to manual firmware through Fastboot, and also explain how to avoid the typical mistakes that even experienced users make.

Xiaomi devices are different from the budget Redmi to the flagship Mi and POCO. Each line can have its own update nuances related to the CPU version, the firmware region or the manufacturer’s policy. For example, the global (Global) and Chinese (China) versions are often updated on different schedules, and some models (for example, the POCO F1) require special actions to unlock the bootloader before the firmware. We took all these subtleties into account to give you a universal guide.

1.Preparing the device for the update: 5 mandatory steps

Before you start an update, there are a few critical steps that need to be taken: neglecting them can lead to data loss, disruption, or even the inability to restore the device, starting with the most obvious but often ignored item: backup.

Backup data should include not only photos and contacts, but also:

• 📱 System settings (Wi-Fi passwords, wallpaper, sound profiles) – they can be saved through Settings → Google → Backup.
• 🔑 Application Logins and Passwords (use Google Smart Lock or specialized managers like Bitwarden).
• 📁 Internal memory files, especially folders DCIM, Downloads and Android/data (It's where game saves are stored).
• 📋 SMS and call logs, applications like this will be suitable for this SMS Backup & Restore.

Checking for free space is another key point: Upgrades over OTA (over the air) require at least 1.5 to 2 GB of free space on the internal drive, and if there is not enough space, the system can interrupt the process in the middle, leading to a bootloop, delete unnecessary files or transfer them to the microSD/cloud.

Also make sure that:

• 🔋 Battery charge is at least 50% (better than 80%).
• 🌐 Internet connection is stable (for the OTA-update).
• 🔌 If you are updating via PC, use the original cable. USB Type-C (cheap analogues can interrupt data transfer).

2. Xiaomi Upgrade Methods: Which One to Choose?

There are three main methods of updating Xiaomi devices: automatic. OTA-Updates, manual installations through Recovery and firmware through Fastboot, each with its own pros, cons and difficulty level.

1.OTA (Over-The-Air) is the easiest and most recommended way, the system itself finds and installs updates over the Internet, suitable for most users, but has limitations:

• ✅ Does not require technical knowledge.
• ✅ Stores all data and settings.
• ❌ Updates come with a delay (sometimes months later than for manual firmware).
• ❌ Not always available for older or regionally-blocked models.

2. Recovery Mode is a semi-automatic method where you manually download a firmware file (.zip) and install it through standard recovery.

• 🔄 OTA-Update "Hanged" or not coming.
• 📦 You want to install a newer version than the system offers.
• 🔓 We need to move to China. ROM Globally ROM (or vice versa without loss of data.

3. Fastboot Mode is the most complex, but also the most flexible method. It requires an unlocked bootloader, PC and command knowledge.

• 🛠️ Recovery of "bricked" devices.
• 🔄 Downgrayd (rollback) on the previous version MIUI.
• 📲 Custom firmware installations (such as LineageOS or Pixel Experience).

3. Step-by-step: how to update Xiaomi through Recovery

If OTA-Update is not available or you want to install a specific version MIUI, Hand-held firmware through Recovery is the best choice, and it works on most Xiaomi, Redmi and other devices. POCO, If they don't have a bootloader blocked, follow the instructions carefully to avoid errors.

Step 1. Download the correct firmware

The firmware file must correspond to:

• 📱 Device models (e.g. Redmi Note 10 Pro) ≠ Redmi Note 10).
• 🌍 Region (Global, China, EEA, India).
• 🔢 Versions MIUI (stable-developer).

The official firmware can be downloaded from the sites:

• Official MIUI portal (for global versions)
• Xiaomi Firmware Updater (archive of all versions)

Step 2. Transfer the file to the device

Downloaded.zip archive (e.g, miui_BLOCKNAMEGlobal_V12.5.1.0.RJWMIXM_...) You must place it in the root folder of internal memory (not in the Downloads folder or in the folder). MIUI!). The file name should not contain Cyrillic or spaces – rename it if necessary.

Step 3. Enter Recovery Mode

Turn off the device, then press the button combination:

• 🔘 Nutrition + Loudness up (for most models).
• 🔘 Nutrition + Loudness down (for some older devices, such as Mi) A1).

In the recovery menu, select the language (usually English) then:

1. Go to Install update.zip to System One (or similar).
2. Select the downloaded firmware file.
3. Confirm the installation and wait until the completion (usually 5-15 minutes).

Step 4: Clearing the cache (required!)

Once you install the firmware, don't restart immediately! Return to the main Recovery menu and select Wipe & Reset → Wipe Cache. This will prevent conflicts between old and new system files. If you skip this step, the device may brake or overheat.

💡

If the device is stuck on the Mi logo after the Recovery update, try re-entering Recovery and selecting Wipe Data (full reset).This will delete all data, but often saves you from bootloop.

Update via Fastboot: for power users

The Fastboot method is a "heavy artillery" for cases where other methods don't work. It allows you to flash the device completely, including the bootloader and radio modules, but requires an unlocked bootloader and knowledge of commands. Attention: this method erases all data on the device!

What you need:

• 🖥️ Windows computer (or Linux/macOS driverless ADB/Fastboot).
• 🔌 Original. USB-cable (better from the set).
• 📦 Firmware in.tgz or.zip format (download only from official sources!).
• 🔓 Unlocked boot loader (instruction below).

Step 1 Unlocking the bootloader

By default, the bootloader on Xiaomi devices is locked to unlock it:

1. Link your Mi Account to your device: Settings → Mi Account → Sync.
2. Activate debugging via USB: Settings → About Phone → MIUI version (click 7 times), then Additional → For Developers → Debugging via USB.
3. Connect the device to the PC and execute the command: adb reboot bootloader
4. Download Mi Unlock Tool, log in to your account and follow the instructions.

⚠️ Note: once unlocked, all data on the device will be deleted! Also note that some models (such as the Redmi Note 8 Pro) require waiting 7-15 days after the account is linked.

Step 2. Firmware through Fastboot

Unpack the downloaded firmware in a folder on your PC. flash_all.bat (for Windows or flash_all.sh (for Linux/macOS). Connect the device in Fastboot mode (clip the power supply) + Volume down) and start the script.

If there is no script, manually run through the commands:

fastboot flash boot boot.img


fastboot flash system system.img




fastboot flash vendor vendor.img




fastboot flash dtbo dtbo.img




fastboot reboot

💡

Fastboot firmware is the only way to restore your device after a major crash (for example, if it doesn’t turn on or only loads in Fastboot).

5.Typical Update Errors and How to Avoid Them

Even experienced users sometimes face problems when updating Xiaomi, and we have collected the most common errors and ways to solve them.

Error "Cannot verify update"

Reason: A corrupted firmware file or a mismatch of model/region.

• 🔹 Download the firmware from the official source.
• 🔹 Check the file name – it should match the device model (e.g., ingres for Redmi Note 10 Pro).
• 🔹 If you're going through China ROM on a global model, it may be necessary to unlock the loader.

2.The device hung on the Mi logo (bootloop)

Causes: firmware conflict, interrupted update or uncleaned cache.

• 🔹 Go to Recovery and select Wipe Cache.
• 🔹 If it doesn’t work, do Wipe Data (full reset).
• 🔹 Older models (such as Mi 5) may need firmware via Fastboot.

3 Loss of IMEI or network after update

This problem is more common when you are running through Fastboot or installing custom firmware.

• 🔹 Check if the modem and nvram modules are stitched (they should be in the firmware archive).
• 🔹 Restore. IMEI through the engineering menu (code #4636##) or specialized utilities such as SN Write Tool.

⚠️ Note: If the speaker is missing after the update or the camera is not working, you probably have firmware from another model. For example, the firmware for the Redmi Note 9 Pro (joyeuse) is not suitable for the Redmi Note. 9S (curtana – despite their appearance, they have different “iron".

6. Update of Xiaomi smart devices: TVs, routers, smart watches

Beyond smartphones, Xiaomi is rolling out a wide range of smart devices that also require upgrades. The process is different for them, but the general principles (backup, stable power) remain the same.

Mi TV and Redmi TV

• 📺 Updates come automatically, but you can check manually: Settings → On TV. → Updating the system.
• 🔌 For manual firmware, download files from the official site and use USB-storage device FAT32).
• ⚠️ Do not turn off the TV during an update – this can cause loss of image or sound.

Xiaomi Mi Router routers

• 📶 Updated via web interface: 192.168.31.1 → Firmware update.
• 🔄 If the router is “hang” after the update, reset it with the Reset button (hold 10 seconds).

Smart watches and bracelets (Mi Band, Amazfit)

• ⌚ Updates come via Mi Fitness or Zepp app.
• 🔋 Make sure your battery is over 30% or the upgrade will be interrupted.

7.How to roll back an update if the new version of MIUI is not working well

Sometimes newer versions of MIUI contain bugs, like the battery goes down quickly, the interface slows down, or some features don't work, and in those cases, you can bring back the previous version of the firmware, which is called downgrade, but it has its own nuances.

Method 1: Recovery (if available)

Download the old version of MIUI (it should be the same branch, for example, from MIUI 13 to MIUI 12.5, but not on MIUI 11) and install it via Recovery, as described above.

• 🔙 Downgrade can lead to data loss (do backup!).
• 🔒 On some models (for example, Xiaomi 12) downgrade is blocked – you will need to unlock the bootloader.

Method 2: Through Fastboot (more reliable)

This method is guaranteed to work, but it erases all data. Download the full firmware (.tgz) of the desired version and thread it through the Fastboot, as described in section 4. Importantly, choose firmware strictly for your model!

⚠️ Note: on devices with MediaTek processor (e.g. Redmi) 9A, POCO M3) Downgrade could lead to loss IMEI or network problems, and in such cases, you'll need to restore SP Flash Tool or contacting a service center.
