How to Switch Xiaomi Mi Band 2: Official and Alternative Methods

Xiaomi Mi Band 2 is one of the most popular fitness bracelets, but over time its standard software can become outdated or not suit the user in functionality. The firmware device allows you not only to update the software to the current version, but also to install custom firmware with advanced features: new dials, notifications from third-party applications, improved sleep tracking or even support for NFC (in some versions).

In this article, we will look at all the current ways to update the Mi Band 2 in 2026, from official updates through the Mi Fit app to manually installing alternative firmware with Gadgetbridge or Notify & Fitness. Special attention will be paid to preparing the device, choosing the right version of the software and solving typical errors. If you have never flashed a wearable device before, do not worry: detailed instructions with step-by-step screenshots and warnings will help avoid critical errors.

Preparation for firmware: what you need to know before starting

Xiaomi Mi Band 2 firmware is an irreversible process, and improper actions can lead to loss of warranty or device failure.

• 🔋 Bracelet charge level is at least 50% (optimally 80-100%). Interrupting the process due to battery discharge is almost guaranteed to turn the device into a brick.
• 📱 The latest version of the Mi Fit app (for official updates) or Gadgetbridge/Notify & Fitness (for custom firmware) is installed on the smartphone.
• 🖥️ If you plan to flash through a PC, prepare drivers for ADB and utilities like MiBandTools or FlashTool.
• 📝 Back up the bracelet data (steps, sleep, notifications) through Mi Fit, as they will be reset after firmware is done.

Important: Mi Band 2 has several hardware revisions (e.g. SH05 and SH06), and the firmware for them is not always compatible. To find out your revision, look under the body of the bracelet - the number is indicated on the sticker next to the QR- code. Installing an inappropriate firmware can lead to irreversible damage to the bootloader.

⚠️ Warning: If your bracelet was purchased in China (the domestic version), the firmware of the global version of the software may block certain features, such as NFC for payment via AliPay. Check the region of the device in the Mi Fit settings before upgrading.

Official Update with Mi Fit: Safe and Easy

The most reliable way to upgrade the Mi Band 2 firmware is to use the Mi Fit app, which is suitable for most users because it does not require technical skills and minimizes risks.

• 🔄 Updates are delayed (sometimes months later than custom firmware).
• 🚫 There is no way to roll back on the previous version of the software.
• 🛠️ The functionality is limited by standard Xiaomi capabilities.

To update the bracelet officially:

1. Open the Mi Fit app and connect the bracelet via Bluetooth.
2. Go to Profile → Xiaomi Mi Band 2 → Update firmware.
3. If a new version is available, click Update and wait until the process is completed (usually takes 5-10 minutes).
4. Do not unplug the bracelet from your phone or leave the app until a successful update is reported.

If the update button is inactive, try:

• 🔄 Reset the bracelet (press the touch button for 10 seconds).
• 📱 Reinstall the Mi Fit app.
• 🌍 Change region in Xiaomi account settings (sometimes updates are released earlier in other countries).

💡

If the bracelet starts to discharge quickly after the upgrade, reset it to factory settings via Mi Fit → Device Settings → Reset. This often solves problems with optimizing new firmware.

Castom firmware: enhanced opportunities and risks

Alternative firmware for Mi Band 2 unlocks the device’s hidden potential: add support for new dials, notifications from Telegram/VK, improve sleep tracking algorithms, or even emulate NFC for informal payment systems.

The most popular custom firmware for Mi Band 2:

• 🛠️ Mi Band Master – adds notification support from any app and new dials.
• 🔧 Amazfit Mod is a ported firmware from Amazfit with improved autonomy.
• 🌐 Custom Firmware by FreeYourBand is an open source project with flexible settings.

To install custom firmware will require:

1. Unlock access to the file system of the bracelet (via ADB or specialized utilities).
2. Download a firmware file (usually in.fw or.bin format) from a trusted source (e.g., the 4PDA forum or XDA Developers).
3. Use the Gadgetbridge or Notify & Fitness app to upload a file to a bracelet.

⚠️ Warning: Some custom firmware requires a downgrade of official software prior to a specific version. For example, installing Amazfit Mod may require a rollback to firmware 1.0.1.14. Check the requirements before you start!

Firmware via PC: for experienced users

If you prefer full control of the process, you can flash Mi Band 2 through your computer using MiBandTools or FlashTool.

• 🔄 Restore the bracelet after a failed firmware ("brick").
• 📥 Install modified versions of the software with patches.
• 🔧 Works with low-level settings (e.g., changing MAC- Bluetooth addresses).

For firmware through the PC you will need:

Download and install drivers for Mi Band 2 (e.g. via Zadig)|Install Python 3.x and pySerial|Library Download MiBandTools utility with GitHub| Connect the bracelet to PC via Bluetooth adapter (USB-Bluetooth 4.0 is recommended)|Unable antivirus (it can block access to ports)

-->

Step-by-step:

1. Connect the bracelet to your PC via Bluetooth and check for detection by the command: hcitool lescan (a device called MI Band 2 should appear on the list).
2. Download the firmware in.fw format and place it in the folder with MiBandTools.
3. Run the firmware command: python mi2_tool.py flash --fw path to file.fw
4. Wait until the process is complete (the bracelet will reboot automatically).

Critical moments:

• 🔌 Use the original USB-Bluetooth adapter — cheap Chinese copies often don’t support the LE Secure Connections required for firmware.
• 🕒 The process can take up to 20 minutes - don't interrupt it, even if nothing seems to be happening.
• 🔄 If the bracelet is not detected, try resetting it by holding the 15-second button.

Solving problems after firmware

Even if you run the Mi Band 2 firmware successfully, you can still have problems, and here are the most common ones and how to fix them:

If the bracelet has stopped responding to charging or is not determined by the devices:

1. Connect it to charging and hold for 30 seconds - sometimes it resets the hover loader.
2. Try flashing through your PC in emergency mode (this may require a special cable).
3. If nothing helps, contact Xiaomi Service Center – some Mi Band 2 models can be restored via JTAG.

Important: If you have custom firmware installed and you encounter bugs, don't rush back to the official one.

• 🔄 Reboot the bracelet (hold the 10 seconds button).
• 📥 Reinstall the firmware (sometimes the file is downloaded with errors).
• 🛠️ Cleaning the cache in a companion application (Gadgetbridge or Notify & Fitness).

💡

If the bracelet is unstable after firmware, try first to reset it to factory settings via Mi Fit → Settings → Reset. 80% of the time it solves the problem without the need for flashing.

Firmware rollback: how to return to the official version

If custom firmware does not suit you or caused failures, you can return the official software from Xiaomi.

1. Download the original firmware for your bracelet revision (e.g., SH05 or SH06) from an official website or a trusted source (e.g., miui.su).
2. Use Gadgetbridge or MiBandTools to upload the file to your device.
3. If the bracelet is not detected, run it through the PC in recovery mode (this may require holding the button when connecting to charging).

Note: When rolling back on the official firmware, all data on the bracelet will be erased, including:

• 📊 Statistics of steps, sleep and training.
• ⏰ Settings of alarm clocks and notifications.
• 🔑 Link to Xiaomi account (re-authorization required).

If the bracelet does not sync with Mi Fit after rollback:

• 📱 Reinstall the application and log in again.
• 🔄 Reset your bracelet settings via Mi Fit → Settings → Reset.
• 🌐 Check that the region in your Xiaomi account matches the firmware region (e.g., global firmware may not work with your Chinese account).

Comparison of firmware methods: which one to choose?

To determine the best way to firmware, evaluate your goals and technical skills:

If you're a beginner, start with an official update. For power users who want more features, Gadgetbridge with custom firmware is the best option.

💡

Before choosing a firmware method, check for reviews of a particular version of the software in forums (such as 4PDA or XDA). Some firmware may contain critical bugs that are not warned in the description.
