How to turn on the Xiaomi Mi Band 3 fitness bracelet after a complete reset: detailed instructions

Resetting the settings on Xiaomi Mi Band 3 is a standard procedure that helps to eliminate software failures, return the bracelet to factory parameters or prepare it for sale. However, after that, many users face the problem: the device does not turn on, does not respond to charging or does not sync with the Mi Fit application. In this article, we will analyze all possible scenarios for activating the bracelet after reset, including cases when the screen remains black, vibrates without reaction or displays a connection error.

It's important to understand that the Mi Band 3 is not just an accessory, but a miniature electronic device with its own firmware. Once reset, it requires not only physical activation, but also the correct binding to the smartphone. We'll look at both the basic steps (charging, power button) and the hidden nuances: updating the firmware through Mi Fit, manually restarting, and ways to solve typical errors like "Disknocked" or "Disknose. If you've tried to turn on the bracelet, but failed, there's a solution for your case.

Why Mi Band 3 doesn't turn on after reset: the main reasons

Before we get to the instructions, we will understand why the bracelet may not respond to activation attempts, and the reasons fall into two categories: hardware (related to hardware) and software (software failures or settings).

• 🔋 Battery discharged. Once reset, the bracelet spends the residual charge on cleaning the memory. If the charge was below 10% before reset, the device may not turn on without recharging.
• 🔄 Incomplete reset: Sometimes the procedure is interrupted (for example, due to a Bluetooth switch off), and the bracelet remains in suspended state.
• 📱 Mi Fit issues: An outdated version of the app, cache, or account conflict can block sync.
• 🔌 Damaged cable/charging connector.Even if the charging indicator is on, contact may be unstable.
• 🤖 Firmware failure: In rare cases, a reset causes system files to be damaged, requiring flashing.

According to statistics of service centers, in 60% of cases the problem is solved by a banal charging of the bracelet for 30-60 minutes, another 25% are due to synchronization errors with Mi Fit, and only 15% are due to hardware malfunctions (for example, a bloated battery or oxidized contacts).

⚠️ Note: If the bracelet vibrates when connected to the charger, but the screen does not light up, this is a sign of a deep discharge. USB-PC port!) for at least 2 hours.

Preparation for Including: What to Do Before Activation

Before you turn on Mi Band 3, follow a few mandatory steps to avoid common mistakes and speed up the process:

1. Check the charger. Connect the bracelet to the charger (preferably from the network, not from the computer). The indicator on the screen should light up in 5-10 seconds. If not, try another cable or adapter.
2. Update Mi Fit. Install the latest version of the app from Google Play or the App Store. Outdated versions may not support the bracelet communication protocol.
3. Turn on Bluetooth and geolocation. Without them, Mi Fit won't be able to detect the device. Android also requires permission to access contacts (to sync profile).
4. Remove the old binding. If the bracelet was previously synced with another account, remove it from the device list in Mi Fit → Profile → My devices.

Pay special attention to the charging point. The Mi Band 3 has a peculiarity: if the battery is discharged to 0%, it may not show signs of life for the first 10-15 minutes of connecting to the network. Don't panic - give the device time to restore the minimum charge.

Method 1: Standard activation after reset

If the bracelet responds to charging (the indicator is on or the battery animation is displayed), try turning it on in the standard way:

1. Turn off the bracelet from charging.
2. Press and hold the touch button under the screen for 5-7 seconds until the Mi logo appears.
3. Wait for the main screen to load. If the bracelet requests a binding, switch to sync with the Mi Fit.

If the screen does not respond to pressing, but the bracelet vibrates when connected to charging, perform a forced reboot:

1. Connect the bracelet to the charger.


2 Hold the touch button for 15-20 seconds.




3. Release the button when the screen goes out and lights up again.

This method works in 80% of cases when the bracelet freezes after reset, and if nothing happens, move on to the next method.

Method 2: Recovery through Mi Fit (if the bracelet is not turned on)

If the Mi Band 3 doesn’t respond to the button but is charging (the indicator is on), try restoring it through the app, which works even when the screen is dead if the bracelet is detected by the system:

1. Open Mi Fit and go to Profile → Add the device.
2. Choose a bracelet. → Mi Smart Band 3.
3. Follow the instructions on the screen. If the bracelet is not detected, click "My device is not displayed" and select "Mi Band 3" manually.
4. Hold the phone to the bracelet at a distance of <50 cm and wait for the vibration.

If the process is suspended during the connection stage:

• 🔄 Reset Mi Fit (close and open again).
• 📱 Reboot your smartphone.
• 🔌 Turn off and reconnect the bracelet to charging for 1 minute.

Critical detail: If the bracelet was previously linked to another Xiaomi account, it must first untie through Mi Fit → Profile → My Devices → Delete. Otherwise, the new sync will be blocked.

Method 3: Manual firmware update (for power users)

If the bracelet is turned on but is unstable (rebooting itself, not synchronizing data), the cause may be a damaged firmware, in which case manual updates through Mi Fit or third-party utilities like Notify & Fitness will help.

Instructions for Mi Fit:

1. Connect the bracelet to the phone and wait for synchronization.
2. Go to Profile → Mi Smart Band 3 → Update firmware.
3. If a new version is available, click "Update" and wait until it is completed (the bracelet will reboot automatically).

Alternative method (via Notify & Fitness):

• 📱 Install Notify & Fitness for Mi Band from Google Play.
• 🔗 Connect the bracelet through the Device menu → Add.
• 🔄 Go to Settings. → Firmware → Verification of updates.

⚠️ Warning: Do not interrupt the firmware update process! If the bracelet stops responding during installation, it can only be restored through recovery mode (special cable and software are required).

Solving Typical Mistakes After Resetting

Even after successful inclusion, the Mi Band 3 can malfunction, and here are the most common problems and solutions:

• 🚫 Unconnected Error: Remove the bracelet from the Mi Fit and add it again. Turn off battery savings for Mi Fit in your phone settings. Try connecting via another phone.
• ⏳ The bracelet is constantly rebooted: Update the firmware through Notify & Fitness. Reset the bracelet again (hold the 20 seconds button). Check the charging contacts for oxidation.
• 📵 No vibration at notifications: In Mi Fit, check notification settings (Profile) → Mi Band 3 → Reset the bracelet (hold the 10 seconds button) Make sure the phone allows Mi Fit to access notifications.

If neither of these methods worked, the problem may be hardware, such as a bloated battery or a damaged board, in which case we recommend contacting the Xiaomi service center (especially if the bracelet is warranty).

💡

If the bracelet turns on but discharges quickly after reset, calibrate the battery: completely discharge it before turning off, then charge it to 100% without interruption, which will help to reset incorrect data on the level of charge.

How to avoid problems in the future: tips for operation

To avoid having to reset the Mi Band 3 in the future, follow these guidelines:

• 🔋 Charging: Use only the original cable or certified analogues. Do not leave the bracelet on charging for more than 2 hours - this reduces battery life. Avoid charging at lower temperatures +5°C or higher +40°C.
• 📲 Sync: Regularly (every 1-2 weeks) sync your data to Mi Fit to avoid losing it. Do not delete the Mi Fit app without bracelet detachment - this can cause crashes.
• 🛠️ Updates: Install all available firmware updates. Before upgrading, make sure the bracelet is at least 50 times charged%.

Also, remember that the Mi Band 3 is not designed for extreme conditions: avoid water (despite the stated IP68, a long dive can damage the device), shocks and overheating. If the bracelet is wet, dry it for 24 hours before charging.

💡

Regular synchronization with Mi Fit and firmware updates reduce the risk of software failures by 70%, and most problems with Mi Band 3 are due to outdated software or improper charging.
