Can I perform a full vehicle OTA upgrade in an underground garage without signal?
Official answer
The Xiaomi SU7 supports OTA upgrades in places without signal, such as underground garages.
Before the upgrade, the necessary upgrade package has already been downloaded and passed system verification, so the entire upgrade process does not require downloading new data.
However, during the upgrade process, the vehicle reports status data. In case of any upgrade anomalies, the service center can perceive them immediately and repair them remotely, avoiding situations where the vehicle cannot be moved. Therefore, it is recommended that owners still perform upgrade operations in environments with good signal.
