For years, Huawei devices used a relatively simple algorithm to generate unlock codes (NCK codes) based on the device’s IMEI and model number. This gave rise to third-party —small software tools that promised free, instant unlocking. The terms v4 and v5 refer to different generations of Huawei’s security algorithms.
If you search for a "Huawei V4 V5 Unlocker" download, you will likely find many websites claiming to have the software. Be extremely cautious for these reasons: Malware and Viruses:
Developers have published Python-based calculators on GitHub that reconstruct the V4/V5 logic.
