There was a reset on the fitness bracelet Xiaomi Mi Band 4 – what to do?

Resetting the settings on Xiaomi Mi Band 4 is an unpleasant but fixable situation, most often faced by users after updating the firmware, discharging the battery to zero or crashing the Mi Fit application. Sudden loss of data about steps, sleep, training and personal settings can be unsettling, especially if the bracelet was used to monitor health or sports goals.

Fortunately, 90 percent of the time, information can be recovered, either in whole or in part, and the key is to not panic and to go by the algorithm, and in this article, we'll look at why it's resetting, how to recover it, and what to do to avoid being lost again, and we'll also talk about the hidden features of the Mi Band 4 that will help speed up recovery.

Why Mi Band 4 is Resetting: The Main Reasons

Setting resets rarely happen by themselves, usually preceded by one of the following events, and understanding the cause will help prevent the data from being lost again.

• 🔋 If the bracelet is 0% depleted and has been uncharged for more than a day, internal memory can become nullified, especially for devices with firmware older than 1.0.9.54.
• 📱 Sync failure with Mi Fit. Forced closure of the application during data updates or changing the phone without transferring the account often leads to a conflict of settings.
• 🔄 Failed firmware update: If the process is interrupted (for example, due to loss of Bluetooth connection), the bracelet can return to factory settings.
• 🔧 Mechanical impacts, impacts, moisture (despite water resistance 5) ATM) Strong magnetic fields sometimes reset the memory chip.
• 🛠️ Manual reset via menu. Accidental tap Settings → Resetting to factory in the menu bracelets – a frequent mistake of new users.

Interestingly, the Mi Band 4 has two types of reset: mild (stores steps for the last 7 days) and hard (complete zeroing), the first usually occurs when software failures, the second - when hardware malfunctions or forced reset.

First steps: what to do immediately after resetting

If you find that the bracelet returned to the factory settings, act on this algorithm:

1. If you change your smartphone, first install the Mi Fit on your old device and try syncing the data.
2. Check the firmware version. Go to the device profile. → If the version is below 1.0.9.54, update it manually (instruction below).
3. Turn off Bluetooth on other devices. Connection conflict can interfere with recovery.
4. Do not reset the bracelet. Any changes (time, notifications, alarm clocks) will overwrite the temporary recovery files.

A critical mistake many users make: they immediately start setting up the bracelet as new, thereby erasing the remaining data fragments. Even if the screen shows "Hello", take your time setting up - first try to restore the backup.

How to recover data after reset: step-by-step instructions

You can get back lost data in three ways: through Mi Fit, through backup, or through a side utility. Let's look at each option in detail.

Method 1: Recovery through Mi Fit (official method)

If the bracelet was tied to a Xiaomi account, the chances of recovery are high.

1. Open Mi Fit on the smartphone that previously had the bracelet connected to.
2. Go to Profile. → My devices. → Mi Smart Band 4.
3. Click Restore Data (option appears if Xiaomi servers have saved a backup).
4. Wait 5-10 minutes, and the steps, sleep and exercise data from the last 30 days should come back.

Important: This method only works if:

• 📱 The bracelet was synced with the app less than 7 days ago.
• 🔄 In the Mi Fit settings was enabled the option Autosynchronization.
• ☁️ Xiaomi account has not been deleted or blocked.

Method 2: Manual recovery from backup

If the automatic recovery didn’t work, try to find a local copy of the data:

1. On Android go to Settings → Memory. → Files. → MiFit.
2. Find the backup folder and check the date of the last file (for example, mi_band4_20231015.db).
3. Copy the file to your computer and use the Mi Band 4 Tool to extract data.

For iOS, backups are stored in iCloud to retrieve:

1. Install iMazing or iExplorer.
2. Connect your iPhone to your PC and find a folder /Apps/MiFit/Documents/.
3. Export files with the.sqlite extension.

Note: backups on iOS are encrypted. Decrypting them will require a password from Apple. ID.

Method 3: Third-party utilities (for advanced users)

If the official methods don't work, you can use tools like Notify & Fitness for Mi Band or Mi Bandage, which allow you to:

• 🔍 Read raw data from the bracelet (even after resetting).
• 📊 Recover the history of footsteps and sleep in the last 7 days.
• ⚙️ Set up hidden parameters (e.g. synchronization frequency).

Instructions for Notify & Fitness:

1. Install the app from Google Play.
2. Connect the bracelet through Settings → Connect the device.
3. Go to the Tools. → Data recovery.
4. Select Count raw data and wait for the process to complete.

Warning: Third-party utilities may conflict with Mi Fit. Before using, disable automatic synchronization in the official application.

💡

If the bracelet is not detected by any application, try resetting it again: press the touch button for 10 seconds until the vibration appears.

How to avoid future data loss: prevention

To avoid taking your reset by surprise, follow these guidelines:

Additional precautions:

• 📲 Backup to the cloud. In Mi Fit settings, enable Cloud Storage (requires a Xiaomi account).
• 🔄 Regular synchronization: Manually update data every 2-3 days, even if autosynchronization is enabled.
• 📱 Link to one device: Avoid frequent reconnection to different smartphones.

Athlete Advice: If you use Mi Band 4 for training, duplicate your data in Google Fit or Apple Health.

💡

The most common cause of permanent data loss is ignoring low-charging warnings, charging the bracelet at below 20% to avoid deep discharge.

Hidden features of Mi Band 4 that will help after reset

Few people know, but Mi Band 4 has hidden features that make recovery easier.

• 🔍 Developer mode. Activated by 5 times pressing About the bracelet in the menu. Allows you to enable Bluetooth debugging.
• 📡 Sync Log. In Mi Fit, go to Settings → About the programme → Event log to see connection errors.
• 🔄 Mi Band 4 Custom Firmware allows you to recover data even after a hard reset (requires root on your phone).

How to turn on the developer mode:

1. Open on the bracelet Settings → The bracelet.
2. Click on the string with the firmware version 5 times in a row.
3. There will be a menu for developers with options Debugging over Bluetooth and Log.

In this mode, you can:

• Export raw data on steps and pulse.
• Set custom dials without restrictions.
• Disable automatic firmware updates.

Warning: Careless use of the developer mode can lead to a complete failure of the bracelet.

Frequent Recovery Mistakes and How to Avoid Them

Many users make things worse by making common mistakes, and here are the most common ones:

⚠️ Warning: Never update the bracelet firmware immediately after resetting. Restore the data first and then update the software. Otherwise, new firmware files will overwrite the temporary recovery data.

• 🚫 Connecting to a new phone without a backup, which erases communication with the previous device and makes recovery impossible.
• 🚫 Using unofficial firmware: Castom firmware often conflicts with Xiaomi servers, resulting in cloud data loss.
• 🚫 Ignoring synchronization warnings. If Mi Fit asks for updates, don't delay it.
• 🚫 Resetting the bracelet through the menu without needing to be used in extreme cases.

Another common mistake is to delete the Mi Fit app when it crashes, which causes local backups to be lost instead of deleting:

1. Clear the app cache in the phone settings.
2. Reboot your smartphone.
3. Try logging into your Xiaomi account through your browser to check for a cloud copy.

If you’re using Mi Band 4 on your iPhone, be especially careful: iOS limits the background of apps, which can cause sync to break.

• Enable the option for Mi Fit Content Update in the background.
• Add the app to Favorites in iOS settings.
• Open Mi Fit regularly to start forced synchronization.

When recovery is not possible: what to do next

Unfortunately, in some cases, data cannot be recovered, and this happens if:

• 🔋 The bracelet discharged to 0% and lay without charging for more than 3 days.
• 🔧 A hard reset was made through the device menu.
• ☁️ Xiaomi account has been deleted or blocked.
• 📱 The phone to which the bracelet was tied was reset to factory settings without backup.

If recovery is not possible, follow this plan:

1. Reconfigure the bracelet, but do not rush to enter personal data. First check the main functions (stepmeter, pulsemeter).
2. Back up your current settings through Mi Fit or third-party utilities.
3. Check the warranty. If the reset is due to a hardware malfunction (such as moisture), contact the service center.
4. Consider switching to a new model. Mi Band 5/6/7 Have an improved backup system and lose data less often.

If you decide to upgrade, consider:

• 🆕 Mi Band 7 supports continuous tracking SpO2 (oxygenation).
• ⚡ Mi Band 6 has a lot of AMOLED-screen and extended sports modes.
• 🔋 All new models are equipped with an improved battery (up to 15 days of operation).

Before you buy a new bracelet, check compatibility with your smartphone. e.g. Mi Band 6/7 Android requires 6.0+ iOS 10.0+.
