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 will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.

Our legal delivery milestone is based on the "Estimated Time of Departure (ETD)". As long as the vehicle enters the port area and customs clearance is completed within the agreed timeframe, any delays in shipping schedules due to the shipping company's capacity adjustments will not be considered a breach on our part. The uncontrollability of maritime transport must be factored into your expectations.
