Xiaomi’s blocked fitness bracelet is a problem that thousands of users face every day, and the reasons range from trivial forgetfulness (injected the wrong PIN three times) to software failures after a firmware update. Unlike smartphones, where unlocking often requires contacting a service center, Mi Band and Smart Band bracelets can be unlocked on their own in 90% of cases – without data loss and without special skills.
In this article, we’ll look at all the current unlocking methods for models from Mi Band 5 to Xiaomi Smart Band 8 Pro, including the rare cases when the bracelet is locked after changing your smartphone or resetting your phone. Special attention will be paid to the hidden features of the Mi Fitness app (formerly Zepp Life), which the manufacturer does not advertise, but which save in critical situations. If your bracelet shows the inscription “Device Locked” or asks you to enter a PIN that you do not remember, you are in the right place.

⚠️ Warning: If the bracelet was tied to another account (e.g., you bought it with your hands), this method will not work.

| Mi Band 7 | 5 minutes | Yes. |
