If the firmware on the Redmi Smart Band Pro can't be updated, please refer to the following troubleshooting methods:
1. The band can't be updated if its battery level is below 20%. After charging the band to 20% or more, try upgrading again;
2. Ensure that Bluetooth is enabled on the smartphone to which the band is paired;
3. Ensure that the band is within the Bluetooth range of the connected phone. Keep them close to each other;
4. Ensure that your phone has a stable internet connection, either through Wi-Fi or mobile data;
5. Try again in a place where there are fewer Bluetooth and Wi-Fi devices to reduce other signal interference;
