| Problem | Likely solution |
|--------|----------------|
| “Modem not found” | Reinstall drivers, try different USB port, disable modem’s “CD-ROM” mode via AT^U2DIAG=0 |
| Wrong unlock code | Some carriers use special algorithm — try another tool like DC-Unlocker |
| Flashing fails | Use original USB cable, disable antivirus temporarily, re-run as Admin |
| Tool flagged as virus | False positive (often due to driver injection). Verify hash on trusted forum like 4pda or HuaweiModem.ru |
If you have a Huawei modem with firmware version 5.8.111 that is locked to a specific network carrier, this guide will walk you through a safe unlocking process using legitimate tools.
Note: We do not support cracked software — using official unlockers ensures your device remains functional and secure.
Two methods:
Method A (Using Windows):
Method B (Using Phone):
Because this tool injects DLL files into the modem’s COM port to bypass security, it is often flagged by Windows Defender as "HackTool:Win32/Keygen." This is a false positive. However, always download from trusted sources (e.g., reputable tech forums like GSM-Forum, XDA Developers, or DNM). Malicious actors have bundled ransomware with fake unlockers.
Safety Checklist:
Note: If your modem has firmware version 22.200.x.x or higher, you may need to downgrade the firmware first using "Firmware Finder" before unlocking.
