Standard Filename: Huawei Modem Unlocker v5.7.7 by Bojs.exe
Back in the early 2010s, network providers sold subsidized USB modems locked to their SIM cards. To switch carriers, you needed an "unlock code" – usually a 16-digit V1/V2 code.
Bojs (a well-known figure in the modem-unlocking scene) released version 5.7.7 as a free GUI-based tool that:
The version number (5.7.7) suggests it was one of the later iterations before Huawei patched the algorithm in newer firmware.
In the world of mobile internet, carrier-locked USB modems (dongles) are a common frustration. You buy a modem from a specific network provider, only to realize you cannot use a SIM card from a different provider when you travel or want to switch networks. This is where Huawei Modem Unlocker V5.7.7 by Bojs enters the picture.
This tool has become legendary in the tech community for its ability to unlock a wide range of Huawei modems quickly and efficiently. If you are looking to liberate your device from carrier restrictions, here is everything you need to know about this software.
Huawei Modem Unlocker V.5.7.7 By Bojs is a piece of digital history – a clever reverse-engineering achievement from the golden age of 3G dongles. But unless you have an archived copy from a trusted source (e.g., your own backup from 2016) and an air-gapped Windows 7 machine, don’t download random copies today.
Instead, check if your modem supports the AT^CARDLOCK command or invest $4 in DC-Unlocker credits. Your PC’s security is worth more than saving a few bucks on a legacy unlock.

Comprehensive Guide to Huawei Modem Unlocker V.5.7.7 by Bojs
In the era of mobile connectivity, being locked to a single network provider can be a major inconvenience. Whether you’re traveling abroad or looking for a better data plan, "unlocking" your device is the key to freedom. One of the most legendary tools in this niche is the Huawei Modem Unlocker V.5.7.7 by Bojs.
This article explores what this tool is, how it works, and what you need to know before downloading it. What is Huawei Modem Unlocker V.5.7.7? Huawei Modem Unlocker V.5.7.7 By Bojs Downlad
Huawei Modem Unlocker V.5.7.7 is a specialized Windows-based utility designed to bypass the network restrictions (SIM locks) on Huawei USB dongles and mobile Wi-Fi devices. Created by a developer known as Bojs, this specific version (V.5.7.7) gained popularity for its simplicity and its ability to handle a wide range of older Huawei chipsets without requiring complex technical knowledge. Key Features
Temporary & Permanent Unlocking: The tool can reset the lock status of the modem.
Modem Reset: It can reset "lock attempts" if you have previously entered the wrong code too many times.
Easy Interface: Unlike command-line tools, it offers a straightforward graphical user interface (GUI).
Service Features: Beyond unlocking, it can often reboot the device or change specific internal settings. How Does the Unlocker Work?
Most Huawei modems use a specific algorithm based on the IMEI (International Mobile Equipment Identity) number. When you insert a SIM card from a different carrier, the device asks for an "Unlock Code" or "NP Code."
The Bojs Unlocker interacts directly with the modem's firmware via the COM port. Instead of just calculating a code, it sends specific commands to the device to: Read the device information. Calculate the required hash. Send the "Unlock" command to the hardware. How to Use Huawei Modem Unlocker V.5.7.7
Disclaimer: Proceed at your own risk. Modifying device firmware can potentially "brick" your device or void your warranty.
Preparation: Ensure your Huawei modem is plugged into your PC and the drivers are correctly installed. Close any dashboard software (like Mobile Partner) that might be using the modem.
Detection: Run the tool and click on "Check Button" or "Refresh." The tool should display your modem's IMEI and firmware version. Unlocking: Click on "Unlock" to remove the SIM restriction.
If your modem says "Blocked" (0 attempts left), use the "Reset" function first.
Finalize: Once the process is complete, unplug the modem, insert a new SIM card, and restart the device. Safety and Download Precautions As this is legacy software, it is no
When searching for a download of Huawei Modem Unlocker V.5.7.7, you must be extremely cautious. Since this is "legacy" software and not an official Huawei product, many download sites bundle it with malware or adware. Essential Tips:
Antivirus: Your PC will likely flag this tool as a "Trojan" or "Riskware." This is common for unlocking tools because they interact with hardware at a low level. However, only bypass this if you trust the source.
Compatibility: This tool works best on older Huawei models (like the E173, E1550, or K3765). Modern 4G/5G "Hilink" modems often require different methods or paid credits.
Backup: Always back up your important data before attempting a firmware-level change. Alternatives to Bojs V.5.7.7
If V.5.7.7 doesn't support your specific model, you might consider:
DC-Unlocker: A professional-grade tool that supports almost all Huawei models (usually requires paid credits).
Huawei Calculator: Simple web-based tools that generate a code based on your IMEI (works for "Old Algo" and "New Algo" models). Conclusion
The Huawei Modem Unlocker V.5.7.7 by Bojs remains a classic "Swiss Army Knife" for users looking to repurpose old Huawei hardware. By breaking the carrier lock, you can save money on roaming and choose the best network for your needs. Always ensure you are downloading from a reputable tech forum to keep your computer safe.

Huawei Modem Unlocker V.5.7.7 is a widely recognized third-party utility developed by "Bojs" used to remove network restrictions from older Huawei USB dongles and modems. By unlocking these devices, users can use SIM cards from any telecommunications provider instead of being locked to the original network. Key Features and Supported Devices The version number (5
The tool is primarily used for modems that utilize the "old algorithm" or early "new algorithm" for generating unlock codes.
Broad Compatibility: It historically supports popular legacy models including the Huawei E1550, E156G, E160, E155, and E1552.
Standalone Functionality: It can often calculate the 8-digit NCK (Network Control Key) and flash codes directly using the device's 15-digit IMEI number.
Utility Operations: Beyond unlocking, versions of this tool often include features to reset the modem, enable/disable the "Virtual CD-ROM," or change the dashboard software. General Unlocking Procedure
While specific steps may vary by version, the general workflow for using a Huawei Unlocker by Bojs is as follows:
Preparation: Install the necessary modem drivers on your PC so the software can detect the device.
Detection: Connect the modem (usually with an "invalid" SIM from a different network inserted) and launch the unlocker tool.
Code Generation: Enter the 15-digit IMEI number found on the modem's label into the software's "IMEI" field. Unlocking: Click "Calculate" to generate the Unlock Code.
Some versions allow you to click "Unlock" directly to send the command to the modem.
Alternatively, you can manually enter the generated code when the modem's dashboard (like Mobile Partner) prompts for a "SIMLOCK Code". Important Considerations
Security Risks: As this is unofficial software often hosted on file-sharing sites, it is critical to scan downloads for malware. Some newer security suites may flag these tools as "potentially unwanted programs" (PUPs).
Unlock Attempts: Huawei modems typically only allow 10 attempts to enter an unlock code. If these attempts are exhausted, the modem may become permanently locked to the original network.
Algorithm Changes: Newer Huawei models (e.g., those using V3 or V4 algorithms) are generally not compatible with this legacy tool and may require more advanced online services or official unlock codes from providers. Huawei Modem Unlocker V.5.7.8 - Google Groups
