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.

If your remitting bank requires verification of the transaction's authenticity, we will promptly provide: a commercial invoice (PI) signed and stamped by both parties, a scanned copy of the vehicle purchase contract, and our legal export enterprise registration certificate from the Ministry of Commerce in China.

This is after-sales support we are very happy to provide. Since overseas alignment machines often lack databases for Chinese brand vehicles, we will send you screenshots of the core chassis parameters from the service manual, making it easier for your technician to manually input the data for precise adjustments.
