Without verification, a malicious actor could intercept the communication between the GWM server and the vehicle, injecting malicious code. In the Jolion’s architecture, even if an attacker intercepts the transmission, they lack the private key required to sign the modified package. Consequently, the vehicle’s Gateway would reject the signature, resulting in a verification failure.
The Haval Jolion's software updates are critical for maintaining its complex driver-assistance systems and improving the user experience of its digital-heavy interior . While the vehicle supports modern delivery methods like Over-the-Air (OTA)
updates, user feedback indicates that dealership-installed firmware remains the most reliable way to access major feature overhauls. Verified Update Improvements

There are two primary methods for updating the Jolion's system: OTA (Over-the-Air) ⚠️ Never interrupt the update process – no
: Available via the built-in data connection or a stable Wi-Fi network. Prompts usually appear on the infotainment screen when an update is ready. USB/Dealer Update
: For major system version jumps (like moving from version 7.4 to 7.6.1), visiting a dealership is recommended. Dealers can access "hidden" firmware that may not be pushed over the air.
The "Verified" status acts as a critical barrier against several specific threats inherent to OTA updates.
⚠️ Never interrupt the update process – no turning off ignition, no removing USB, no switching menus.
