This issue occurs due to an extremely rare software bug during the device's operation, which causes an abnormal software state, triggering the protective mode (after-sales mode). The hardware remains unaffected. A new software version has fully addressed this issue, ensuring no impact on future use or updates. You should not encounter this problem again after updating to the new version.
