The latest update, Hutool 3.9 UPD, brings a plethora of exciting changes, enhancements, and new features to the table. Some of the most notable additions include:
series. Older versions of the tool cannot communicate effectively with these newer firmware versions to reset or code the unit. SSH and SSH-over-USB Access
Before diving into code, understand the why . Pre-3.9, Hutool was excellent but fragmented. The 3.9 UPD introduced three core philosophies:

Always connect a (minimum 50–100 Amps continuous power) to the vehicle's battery terminals. Infotainment modules draw significant current during coding; a sudden voltage drop will corrupt the flash memory. Phase 2: Interface Calibration
Hutool 3.x版本是该工具库发展历程中的一个重要里程碑。相较于早期版本，3.x系列实现了，将核心功能（hutool-core）与扩展模块（如HTTP、加密、Excel）分离，支持按需引入依赖，大幅降低了项目体积。同时，3.x版本还升级了依赖库，增加了一系列新功能，并针对性能进行了深度优化。
Security is paramount. The 3.9 UPD updates strengthened SecureUtil , providing easier access to common algorithms like AES, DES, and RSA. AES encryption: The latest update, Hutool 3
