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 cannot privately forge or re-stamp the original vehicle nameplate (this is illegal). If the nameplate is unclear, we will rely on the clear VIN on the windshield and the engine stamp as supplementary proof, and we will warn you of this risk before shipping.

Because it's not a one-time transaction. Only by ensuring compliance checks, improving after-sales service, and providing parts can a good reputation be established, leading to repeat purchases and long-term cooperation.
