Resetting the settings on Xiaomi Mi Band 3 is a common measure when selling a bracelet, crashing or switching to a new smartphone. However, after this procedure, many people face the problem: the gadget is no longer determined by the phone, does not sync with the Mi Fit application or permanently disconnects. In this article, we will analyze the step-by-step connection algorithm, typical errors and ways to fix them, from compatibility checks to manual Bluetooth settings.
The Mi Band 3 (codenamed XMSH08HM) is that it returns to factory settings after reset, including the communication protocol, which means that even if the bracelet used to work with your phone, it may now require re-authorization in your Mi Account or firmware update, and we've taken into account all the nuances from choosing the right version of the application to handling errors like "Disabled Connection" or "Device Not Found."
Why does Mi Band 3 not connect after resetting?
