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.

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.

We use an internationally certified electronic signature platform (such as DocuSign or Adobe Sign). Each signed contract generates a digital certificate with a timestamp and encrypted hash value, which has full legal defense effectiveness in international arbitration courts.
