To update the firmware on the Xiaomi Smart Band, please refer to the following steps:
Open the Mi Fitness APP >> select [Device] >> [Firmware updates] >> If a new version is found to be available for update, tap to download the upgrade package. After downloading the upgrade package, it will be automatically pushed to the band. After receiving the upgrade package, the band will automatically upgrade and restart.
Note:
The battery level of the band needs to be kept at 20% or above during the upgrade. During the upgrade process, the band needs to remain connected to the phone, try to keep the band close to the phone, and try to keep the Mi Fitness APP running in the foreground. If the APP is running in the background, it can be detected and stopped, causing the upgrade to fail.
