Implemented on modern Huawei smartphones and routers. These algorithms do not rely solely on the IMEI. They incorporate unique hardware keys embedded in the device's processor (such as Kirin chipsets) and secure boot signatures.

Mobile network operators lock devices to ensure customers remain with their service for the duration of a contract. Huawei uses specific mathematical algorithms to generate these locks based on the device's IMEI.
: A Python-based tool that supports some newer v4 algorithms. It uses an MD5 hash calculation based on the device's IMEI to generate "Unlock" and "Flash" keys.
Devices with blocked unlock attempt counters (usually after 10 failed attempts) require specialized firmware flashing or pinout methods to reset the counter before the code can be accepted.
