While there isn't a single "academic" paper from Huawei (as these algorithms are proprietary), the community has documented the logic through reverse engineering: Algorithm Reconstruction (v3/v4):
The "New Algo" is specifically required for popular 4G/LTE mobile WiFi (MiFi) devices and USB modems. Examples include: Huawei E8372, E3372 Huawei B310, B311, B315, B525, B535 Huawei E5785, E5787
: A more secure "New Algo" introduced for newer 4G modems and routers. Unlike earlier versions, V4 calculation is more complex; some newer devices may even require a 16-digit unlock code , which standard offline calculators often cannot provide. Functionality and Usage huawei unlock code calculator v3 v4 offline new algo
An offline calculator does not send your IMEI to a remote server. This protects your privacy and works even when you do not have an internet connection (for example, if the modem is locked and cannot get online).
One of the biggest advantages of an calculator is data privacy. You do not need to upload your IMEI to a web server, which mitigates the risk of IMEI cloning or blacklisting. While there isn't a single "academic" paper from
: The user provides the 15-digit IMEI number , typically found on a sticker under the device's battery or cover.

Note: It is crucial to determine if your device is a V3 or V4 model before using the tool, as using the wrong algo can increase the chance of hard-locking your device. How to Use the Huawei Unlock Code Calculator V3 V4 Offline Using these tools typically involves the following steps:
Introduced to secure newer modem firmware, the V3 algorithm changed how security keys interact with the device IMEI. Standard V1 calculators cannot unlock devices running V3 firmware. V4 Algo (Latest Algo)
