Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.

We can purchase the hardware (diagnostic device) on your behalf. However, the original online diagnostic accounts (especially those involving anti-theft programming and module matching) have strict domestic IP location and real-name authentication restrictions, making it very difficult to log in stably from overseas for a long time, and we cannot guarantee technical support for this.

Under FOB terms, booking is a legal obligation of the buyer. If your freight forwarder fails to provide the shipping order (S/O) in time, resulting in vehicles exceeding the free storage period at our warehouse or port, the buyer will have to pay the high daily storage fees before shipment.
