Historically, Huawei devices utilized an older algorithm that required an 8-digit unlock code. However, as security measures evolved, Huawei introduced newer algorithms that utilize a 16-digit code, often referred to in technical circles by the internal project name or update designation, "UPD" (or simply as the "New Algo"). This paper examines how these codes are generated and the tools used to calculate them.
