It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blind electrical modifications on modern integrated circuit vehicles.

Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades.

Under CIF (Cost, Insurance, and Freight) terms, we will insure your vehicle with a reputable international insurance company for "All Risks" before shipment. If total loss or partial damage occurs during sea transport, the risk transfers to you once the goods cross the ship's rail. However, sellwellauto will not stand by; we will assist you in preparing complete claims documentation (such as the bill of lading, invoice, and damage photos) to initiate a cross-border claim process with the insurance company, minimizing your financial loss.
