Reflashing Xiaomi Mi Band 5: official and alternative ways

Why upgrade to the Mi Band 5 firmware?

The Xiaomi Mi Band 5 fitness bracelet remains a popular device even years after its release, thanks to a balance of functionality and price. However, over time, standard software can become outdated: there are bugs with synchronization, sensors are incorrectly working or new features from the latest versions of the Mi Fit. Firmware helps solve these problems, but requires caution.

Official updates via Mi Fit (or Zepp Life for new regions) are usually safe, but not always available for all regions at the same time. Alternative methods — such as manual firmware through ADB or custom firmware installation — open access to advanced features (such as AOD, additional dials or a corrected pedometer algorithm), but are fraught with the risk of “bricking” the device.

Before you start, note: Mi Band 5 does not support rolling back firmware to an earlier version through standard methods. If after the update there are problems, you can only return the old software through complex manipulations with fastboot or contacting the service center.

Preparation for flashing: what to do in advance

Regardless of the method chosen, preparing the device and PC will reduce the risk of failure.

1. Open the Mi Fit (or Zepp Life) app.
2. Go to the section with the device → Bracelet settings → About the program.
3. Remember or take a picture of the firmware version (e.g. 1.0.3.54).

Next, make sure that:

• 🔋 The bracelet has a charge of over 50%, and interruption of the process due to discharge can render the device inoperable.
• 📱 The latest version of Mi Fit (or Zepp Life) from Google Play / App Store is installed on the smartphone.
• 🖥️ For manual methods, you will need a Windows PC 10/11 macOS, and the original USB-bracelet.
• 📡 Stable Internet connection (to download firmware).

If you plan to use ADB (for example, to install custom firmware), additionally:

• 🛠️ Download and install Android SDK Platform-Tools (includes adb and fastboot).
• 🔗 Put the debugging on. USB on the bracelet (instruction below).
• 📂 Create a firmware folder on disk C: (for example, C:\MiBand5_Firmware) — It will make it easier to work with teams.

💡

If the bracelet is not detected by PC through ADB, try to use USB-external power hub – sometimes it solves connection problems.

Method 1: Officially Update with Mi Fit (Safeest Method)

This is the standard method recommended by Xiaomi, which requires no technical skills and is minimally risky, but is subject to regional restrictions, for example, users from Russia can receive updates later than in China or Europe.

Instructions:

1. Connect the bracelet to your smartphone via Bluetooth.
2. Open Mi Fit, select your Mi Band 5 from the device list.
3. Go to Bracelet Profile → Firmware Update.
4. If a new version is available, click Update and wait until it is completed (the bracelet will reboot automatically).

Update time: ~5-10 minutes. During this period:

• ❌ Don't turn off Bluetooth.
• ❌ Don't leave the Mi Fit app.
• ❌ Do not remove the bracelet from the charger (if the upgrade goes through it).

💡

Official updates are tested by Xiaomi, but may contain regional restrictions (for example, disabled features for the Russian Federation).

⚠️ Warning: If the bracelet is no longer synced after the upgrade, try removing it from the Mi Fit and adding it again. 90% of the time, this solves the problem.

Method 2: Manual update via ADB (for power users)

This method is suitable if the official update is not available in your region or you want to install a specific firmware version (e.g., Chinese with advanced features).

Steps:

1. Turn on USB debugging on the bracelet: Go to Bracelet Settings → About. Tap 5 times on the firmware version number until the notification Developer Mode is on. Go back to the main bracelet settings, there will be a new item for developers. Activate ADB debugging.
2. Connect the bracelet to your PC: Use the original cable (not unknown Chinese counterparts may not work). In Windows Device Manager, check that the bracelet is defined as Android ADB Interface.
3. Download firmware: Up-to-date versions of firmware can be found on the 4PDA or Xiaomi.eu forums. The firmware file usually has the.fw or.bin extension.

Install firmware through ADB:

adb devices


adb push firmware.bin /sdcard/




adb shell am broadcast -a android.intent.action.MASTER_CLEAR




adb reboot bootloader




fastboot flash firmware firmware.bin




fastboot reboot

If the bracelet does not turn on after rebooting or is stuck on the logo, try:

• 🔄 Repeat the procedure with another version of the firmware.
• 🔌 Hold the bracelet button pressed for 15 seconds for forced reboot.

⚠️ Note: Firmware via fastboot erases all data on the bracelet (steps, dial settings, etc.) It can only be restored through a backup in Mi Fit.

Method 3: Install custom firmware (extended functions)

Custom firmware (such as Amazfit Mod or Mi Band 5 Custom Firmware) add features that are not available in the stockware:

• 🌙 Always on screen (AOD).
• 🎨 Additional dials and animations.
• 📊 Improved algorithms of pedometer and pulsemeter.
• 🔒 Ability to disable forced synchronization with Mi Fit.

There are, however, downsides:

• ⚠️ No official support - bugs are fixed by enthusiasts.
• ⚠️ Risk of incompatibility with future Mi Fit updates.
• ⚠️ There may be problems with data synchronization (e.g. steps may not be transmitted to the application).

Installation instructions:

1. Download the archive with custom firmware (for example, with XDA Developers).
2. Unpack the files in a folder. C:\MiBand5_Custom.
3. Connect the bracelet to your PC in ADB mode (as in Method 2).
4. Run install.bat (for Windows) or execute commands from README manually.

After installation:

• 🔄 The bracelet will reboot 2-3 times – this is normal.
• 📱 You may need to reconnect it to Mi Fit (remove the old device and add it again).
