Download Huawei Modem Unlocker V5.8.1b By Bojs Latest

Huawei modems use a 16-digit numeric code (or sometimes 8-digit) to remove the SIM lock. This code is generated using a cryptographic algorithm that takes the modem’s IMEI (International Mobile Equipment Identity) as input.

Huawei Modem Unlocker V5.8.1b contains a lookup table and reverse-engineered algorithm (often referred to as the "V1–V3 algorithm") that calculates the correct unlock code instantly.

Example Algorithm Logic (Simplified): Unlock Code = (IMEI_checksum * known_factor) MOD 10^16

Bojs’ tool automates this process, eliminating human error in manual calculations.

Step 1: Install Drivers Ensure your modem is recognized by Windows. Insert the modem → Cancel the auto-run setup → Open Device Manager → Look for "Ports (COM & LPT)" → You should see "Huawei Mobile Connect - 3G Modem (COMx)". Note the COM port number.

Step 2: Disable Mobile Broadband Software Close any dialer software like Mobile Partner, HiLink (web UI), or third-party connection managers. These block direct COM port access.

Step 3: Run the Unlocker

Step 4: Generate Code

Step 5: Input the Code

Step 6: Success The modem will reboot. You can now use any SIM card globally.

While the tool was revolutionary, it wasn't without risk. If a user entered the wrong code too many times (usually more than 10 attempts), the modem would hard-lock permanently. Furthermore, newer Huawei modems eventually patched these algorithm vulnerabilities, moving to "server-based" unlocking where codes could no longer be calculated offline.

To understand the popularity of this tool, one must understand the market of the early 2010s. Telecom companies subsidized USB modems to get users on their networks. A modem bought from Provider A would reject a SIM card from Provider B. This forced users into expensive roaming charges when traveling or left them stranded with bad reception.

While manufacturers included "unlock code" mechanisms, telecoms rarely handed them out. This gave rise to a grey market of unlock code sellers and, eventually, free software solutions. Huawei modems use a 16-digit numeric code (or

In the world of mobile broadband, Huawei has established itself as a dominant manufacturer of USB modems (often called "dongles" or "sticks") and Portable WiFi hotspots. Devices like the E303, E3531, E3272, and K3765 are popular globally.

However, a common frustration among users is SIM-locking. When you purchase a modem from an Internet Service Provider (ISP) like Vodafone, T-Mobile, Smart, or Globe, they often "lock" the device to their network. This prevents you from using a cheaper SIM card from a competitor.
