: Huawei has used different security algorithms over time, commonly referred to by the community as V1, V2, and V3 (V201). Tools like Eggbone were built to reverse-engineer these mathematical models. 2. Operational Steps
Modern Android versions block the “unlock code” dialog from being triggered via simple AT commands. Many new Huawei phones (P40 series, Mate 40, Nova 9, etc.) use and carrier-specific configs that ignore legacy codes.
The Eggbone Huawei Unlock Code Calculator is a legacy software tool used to generate NCK (Network Control Key) unlock codes for older Huawei modems and MiFi pocket routers (v1, v2, and v201 algorithms). It calculates the unlock code based on the device's unique number.
