Xiaomi Mi Band 4: how to set up after reset to factory settings

Resetting Xiaomi Mi Band 4 to factory settings is a necessary measure when you freeze, synchronization errors or before selling the device. However, after this procedure, the bracelet turns into a “clean sheet”: all settings, training data, notifications and even binding to your Mi Account disappear. You can restore the functionality of the gadget in 10-15 minutes, but only if you know the key nuances.

This article provides step-by-step instructions for setting up the Mi Band 4 after a reset, including linking to the Mi Fitness app (formerly Mi Fit), restoring notifications, setting up screens, and solving common bugs. We'll focus on synchronizing data, as many users lose their activity history due to incorrect actions. If you've already tried to set up the bracelet but it doesn't "see" the phone or doesn't update the firmware, here are the solutions.

⚠️ Important: After resetting, the Mi Band 4 automatically goes to standby mode for couples with the phone. If you don't connect it to the app within 5 minutes, the bracelet may lock again - this is an accidental reset protection!

Before you start setting up Mi Band 4, make sure you have everything you need. Without these prepared elements, the process can be delayed or ended in error.

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ with Mi Fitness installed (you can download it from Google Play or App Store).
• 🔋 At least 50% charge, Mi Band 4 can interrupt synchronization.
• 📶 Stable Internet connection (Wi-Fi or mobile network) for downloading firmware updates.

3. Reboot your smartphone.

⚠️ Warning: If you sell or transfer the bracelet to another person, be sure to untie it from your Mi Account account in the app settings. Otherwise, the new owner will not be able to link the device to his profile.

Step 1: Linking Mi Band 4 to your Mi Account

The first and most critical step is to link the bracelet to your Mi Fitness profile, without which all other settings will not be available, the process takes no more than 3-5 minutes, but requires accurate follow-up.

3. In the list of devices, find the Mi Smart Band 4 and tap it.
4. The bracelet will begin to vibrate - confirm the pairing on the phone (click "Connect").

If at this stage there is an error "Can not connect", check:

• 🔋 Bracelet charge: if the indicator flashes red, connect the Mi Band 4 to charge for 10-15 minutes.

If the bracelet was previously linked to another account, it must first untie it through Settings → Mi Smart Band 4 → Untie the device in the old profile. Otherwise, the new owner will not be able to connect it.

Step 2: Update firmware and restore data

3. If a new version is available, click “Update” and wait until it is completed (the bracelet will reboot automatically).

⚠️ Warning: Do not interrupt the upgrade process, even if it takes more than 10 minutes.If the bracelet battery runs out during firmware, the device can turn into a "brick" (you will need to flash it through the PC).

After updating the firmware, the application will offer to restore data from the cloud (if synchronization was previously enabled).

1. Go to Profile → Settings → Data Synchronization.
2. Click on “Restore” and select the latest backup.

💡

If the bracelet does not sync steps after updating, try calibrating the sensor: go to Settings → Step Sensor → Calibration and walk 20 steps with your phone in your hand.

Step 3: Set up notifications and calls

One of the key features of the Mi Band 4 is to alert you to calls and messages, and when you reset, you reset those settings, and the bracelet stops vibrating when you're noticing them, and you can get it back up.

1. In the Mi Fitness app, select Mi Smart Band 4 → Notifications.
2. Turn on the Call Notification switch.
3. In the Notifications from applications, select messengers (WhatsApp, Telegram, etc.) from which you want to receive notifications.
4. Set up the Notification Style: only vibration, sound + vibration or screen blinking.

2. In Mi Fitness, select Dials → Add → Select a file.
3. Specify the path to the downloaded file and confirm the installation.

⚠️ Warning: Insufficient installation of custom dials can cause malfunctions of the bracelet. Use only verified sources and do not install files from unknown developers.
