Why does the Xiaomi OpenWear Stereo Pro fail to update firmware?

If the Xiaomi OpenWear Stereo Pro fails to update firmware, please refer to the following troubleshooting methods:
1. Check if the Bluetooth connection is stable. Firmware updates require a stable connection between the earbuds and the device. Weak or intermittent Bluetooth signals can interrupt the update process.
2. If the earbuds or the charging case have low battery levels, the firmware update may not start or may fail midway. Please ensure that the earbuds and charging case are fully charged before updating.
3. Ensure that the Xiaomi Earbuds App is updated to the latest version.
4. Check if the network connection is stable. Slow or unstable internet can cause download or verification failures.
5. Other Bluetooth devices or apps running in the background may interfere with the update process. Close unnecessary apps and move away from other active Bluetooth devices.
6. If the problem persists, please submit feedback in the Xiaomi Earbuds App.
