: This tool generally only works on legacy USB modems (e.g., E303, E3131, E353). It does not work for modern Huawei smartphones (like the P or Mate series) or newer 4G/5G routers.
This version specifically targets the "v3" or "v201" security algorithm used in older to mid-generation Huawei 3G and 4G devices. Unlike earlier v1 and v2 versions, the v3 algorithm was more complex, requiring updated software to successfully extract the correct . GitHubhttps://github.com

If the V3 calculator fails, several alternatives exist, primarily focused on bootloader unlocking for phones rather than modems. For advanced users, tools like can unlock the bootloader on many Kirin-powered devices using a hardware "testpoint" method. A brute-force method, using scripts to try thousands of possible codes via the fastboot oem unlock command, is also possible for some older models, though it is very time-consuming and has a low success rate.
