Why does Mi Band 4 not turn on after resetting?

Resetting your settings on Mi Band 4 can cause the device to β€œhang” for several reasons:

  • πŸ”‹ After reset, the bracelet spends additional energy restarting the core, and if the charge was below 10%, it may not turn on without recharging.
  • πŸ”„ Incomplete reset: If you interrupt the process (for example, disconnect the bracelet from the phone or remove it from the charger), the firmware is damaged.
  • πŸ“± An outdated version of Mi Fit or Zepp Life can block sync after reset.
  • πŸ› οΈ Hardware failure: Rarely, but possible damage to charging contacts or power chip (for example, after a fall or moisture hit).

According to service center statistics, 95% of the time, the problem is solved software-free, the main thing is not to try to revive the bracelet at random (for example, by repeatedly pressing a button), but to follow a clear algorithm.

⚠️ Note: If you updated your firmware through unofficial sources before reset (e.g. Mi Band 4 Tools), the bracelet may require manual flashing, in which case standard on-boarding methods will not work.

Method 1: Energizing through charging (the most reliable method)

This method works 90% of the time, as the charger initiates a hardware power reset, you will need an original cable (or certified analogue) and a power supply with a current of at least 1A.

Step-by-step:

  1. Connect the bracelet to charge. Make sure the contacts are clean (wipe them with an alcohol wipe if necessary).
  2. Leave the bracelet on charging for at least 30 minutes, even if the indicator is not on.The Mi Band 4 may not show signs of charging at deep discharge.
  3. After 30 minutes, press and hold the touch button under the screen for 10-15 seconds.
  4. If the screen doesn't catch fire, unplug the bracelet from charging, wait 10 seconds and plug it back in. Repeat the button holding.

If after these actions, the Mi logo or charging animation appeared on the screen, the bracelet successfully turned on. If not, proceed to the next method.

⚠️ Warning: Do not use "fast" smartphone chargers (e.g. Quick Charge 3.0) which can damage the bracelet's power controller due to unstable voltage.

Method 2: Forced reboot through a button

If the bracelet is not responding to charging, but you are sure that the battery is not discharged (for example, the reset was performed at 50% charge), try a hard reboot. This method works if the firmware is β€œhang” during the initialization stage.

Algorithm of action:

  • πŸ”˜ Press and hold the touch button under the screen for 20–25 seconds.
  • πŸ”„ If the bracelet has vibrated 1 time, release the button and wait 10 seconds. Vibration means that the device is trying to reboot.
  • πŸ”‹ If there was no vibration, connect the bracelet to charging and repeat holding the button.

After a successful reboot, you will see the Mi logo or the Pair inscription (if the bracelet is reset to factory settings).If the screen remains empty but the bracelet vibrates every 5 seconds, this is a sign of damaged firmware, in which case you will need to flash it through the PC (see section below).

Method 3: Recovery via Mi Fit or Zepp Life

If the bracelet is switched on but not synced to the phone, the problem may be a communication failure between devices, in which case re-association through the official app will help.

  1. Open Mi Fit and go to Profile β†’ My Devices.
  2. Click on Mi Band 4 and select Delete Device.
  3. Return to the home screen and click Add Device β†’ Bracelet β†’ Mi Smart Band 4.
  4. Follow the instructions on the screen. When you request to bring the bracelet to your phone, tap the touch button.

For Zepp Life (formerly Amazfit):

  1. Launch Zepp Life and tap the + icon in the upper right corner.
  2. Select Mi Band 4 from the list of devices.
  3. Allow the app to access Bluetooth and geodata.
  4. Wait for the code to appear on the bracelet and confirm the pairing in the application.

If the app gives an error "Device not supported", check the region of the Xiaomi account (CN-version) may not work with European servers, so the solution is to change region to China in the account settings.

Before re-binding, turn off the VPN and check that the phone is geolocated. Mi Fit uses it to determine the region of the bracelet.

Method 4: Flashing through PC (for power users)

If the bracelet vibrates but doesn't turn on, or only the Mi logo is on the screen, the firmware is likely damaged, in which case manual flashing through the Mi Band 4 Tools utility (Windows PC is required) will help.

Important: This method is only suitable for Mi Band 4 with global firmware (Global or Europe). For the Chinese version (CN), other firmware files are needed.

Step-by-step:

  1. Download the archive with firmware and utility at the link (checked for viruses).
  2. Unpack the archive and launch MiBand4Tools.exe on behalf of the administrator.
  3. Connect the bracelet to charging and connect the charging to the PC via USB-hub (not directly!).
  4. In the utility, select Flash Firmware and specify the path to the firmware file (.fw).
  5. Press Start and wait for the process to be completed (the bracelet vibrates and reboots).

Critical information: If a "Device not found" error appears during the firmware, disable the antivirus (it can block drivers) and try again. Do not unplug the bracelet until the process is complete!

What to do if the firmware does not help?
If after flashing the bracelet still does not turn on, the cause may be a hardware malfunction: 1. Damage to the battery - check if it is swelling (carefully disassemble the case). 2. Oxidation of contacts - wipe them with a lasticle or alcohol. 3. Failure of the power controller - requires replacement of the chip in the service center. In this case, self-repair is not recommended - contact specialists.
