Note: Many users confuse (to install custom ROMs) with SIM/Network Unlocking (to use other carriers). Huawei stopped bootloader unlocking entirely in 2018. Never trust a "bootloader unlock calculator"—they are 100% scams.
The older generation of Huawei phones (before 2018) used a relatively simple, well-documented algorithm. Developers reverse-engineered this algorithm, allowing them to create tools that could generate codes offline. Most "calculators" you find online are built on this legacy code.
The promise of an "online calculator" is simple: You enter your IMEI, click "Generate," and receive your unlock code instantly for free or for a low fee.
Never recommend a "calculator" that is a simple .exe file from an untrusted source, as these are often malware.
