How to reset the fitness bracelet Xiaomi Mi Band 4 to factory settings: all ways

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular devices for monitoring activity, despite the release of new models. Over time, users face the need to reset to factory settings - whether before sale, due to software failures or to fix synchronization errors.

In this article, we will discuss all the official and hidden ways to reset the Mi Band 4, including recovery through the Mi Fit app and hardware reboot, and pay special attention to nuances that are not written about in standard instructions, such as how to avoid a 5001 error when synchronizing after a reset or what to do if the bracelet does not respond to pressing.
