What to do if the Xiaomi Sound Party firmware upgrade fails?

The Xiaomi Sound Party does not support OTA (over-the-air) firmware upgrades, so you cannot perform firmware upgrades on your own.
If the firmware needs to be updated, it is necessary to contact the official after-sales service center for assistance. The staff at the service center can ensure that the firmware is correctly installed without affecting the device’s normal operation. This design helps maintain the speaker’s performance, stability, and compatibility with connected devices.
You should avoid attempting unofficial firmware upgrades or third-party modifications, as these could lead to malfunctions, instability, or void the warranty. Using authorized service ensures updates are applied safely and the speaker continues to deliver reliable audio quality, battery performance, and connectivity. Overall, firmware maintenance is handled through professional support rather than self-service, simplifying the process for you and preserving device longevity.
