What to do if the Xiaomi Smart Band 9 Active prompts that the upgrade fails?
During the upgrade process of the Xiaomi Smart Band 9 Active, if the connection is disconnected (Bluetooth connection is disconnected), the installation package will fail to be transferred. At this time, the band will restart and return to the version before the upgrade.
Please refer to the following steps to troubleshoot:
1. If the APP has not performed other operations and is still in the upgrade transmission interface, after the device reconnects and completes synchronization, please go to a place with fewer Bluetooth and Wi-Fi devices and tap [Retry] to reduce other signal interference. If the APP has returned to the function interface, please go to a place with fewer Bluetooth and Wi-Fi devices, tap [Check for updates], and re-initiate the upgrade;
2. After re-initiating the upgrade, the band upgrade progress will be resumed from the last failed point (0% re-transmission for full upgrade);
3. If the update fails again under Bluetooth connection, it is recommended to select [Reset] on the device (this operation can unbind the band), restart the paired phone, and after the phone and device restart, rebind with the APP to upgrade again;
4. Keep the band and mobile phone close to each other, and follow the upgrade prompts. Keep the Mi Fitness APP upgrade interface in the foreground and wait patiently for the upgrade to complete;
5. When the transfer interface displays 100%, it means that the new version upgrade package has been transferred. The interface preparing to update verification is verifying the integrity, legality, and encryption of the upgrade package. If the band stays on the "Preparing for update verification" interface for a long time, this is a normal upgrade process. Please wait patiently.
