HiSuite Proxy is a third-party Windows application. Its primary function is to intercept communication between your computer (running HiSuite) and Huawei's servers. By doing this, it can trick the official update mechanism into installing an older version of the firmware than what is currently on the phone.

HiSuite Proxy v313 refers to a versioned utility (often circulated as “v3.1.3” or similar) used to facilitate communication between Huawei Android devices and PCs by bridging or modifying the normal HiSuite connection. HiSuite is Huawei’s official device-management software; a “proxy” tool intercepts or emulates parts of that communication to enable tasks HiSuite doesn’t natively support, such as ADB-like access, data extraction, flashing, or bypassing restrictions.

Unlike third-party flashing tools (like IDT or HCU Client), HiSuite Proxy does not modify the firmware files. It simply redirects Huawei's official update server to point to a specific official firmware file. Because the files are signed by Huawei, your device's bootloader and Secure Boot will reject the installation if the file is corrupted or unofficial.
Because specific tool versions like "v313" are often distributed through community forums (like XDA Developers or GSM hosting forums) and links frequently change or become outdated, I have written a complete article detailing what this tool is, how it works, and the general method for locating a safe download link.
Improved compatibility with EMUI 10, 11, 12, and HarmonyOS.
