Why does the Xiaomi Smart Band 9 stay on the "Preparing for Update Verification" interface for a long time after the transfer is 100% completed?

Question

Accepted Answer

After the transfer interface shows 100%, it means that the new version upgrade package has been transferred. The interface of preparing for update verification is verifying the integrity, legality, and encryption of the upgrade package. This is a normal upgrade process. Please wait patiently.
