Step-by-Step Process
- Install Drivers – Ensure the Huawei HiLink drivers are installed. Connect the E5577Cs-603 via USB. Windows should auto-detect it as a modem/RNDIS device.
- Run USBLoader as Administrator – Right-click the executable and select Run as administrator.
- Connect – In USBLoader, select the correct COM port (usually the PCUI or Diag port). Click Connect.
- Read Info – Click Read Device Info to confirm communication.
- Perform Action:
- For unlocking: Go to the Unlock tab, enter the NCK code, and click Unlock.
- For band locking: Go to Band Settings, uncheck automatic, select your desired LTE bands, and click Apply.
- Reboot – After any change, restart the router (either via USBLoader’s reboot button or physically power-cycling).
3. Band Locking (Force LTE Bands)
This is a power-user favorite. The E5577Cs-603 usually auto-scans all available bands. With USBLoader’s band-lock feature, you can force the device to use only specific LTE bands (e.g., Band 3, Band 7, Band 20). Benefits include: The Ultimate Guide to the USLoader E5577CS603 Portable:
- Avoiding congested bands during peak hours.
- Prioritizing longer-range bands in rural areas.
- Disabling slower 3G/2G fallback.
8. Troubleshooting USB Tethering
| Issue | Likely Fix |
|-------|-------------|
| Device not detected | Try different USB cable (data-capable, not charge-only) |
| “Unidentified network” (Windows) | Disable/enable adapter, restart E5577 |
| No IP assigned | Set static IP: 192.168.8.2, mask 255.255.255.0, gateway 192.168.8.1 |
| Works for 5 min then stops | USB power saving – disable “Allow computer to turn off this device” in power settings |
| Linux not creating usb0 | Check lsusb for Huawei (12d1:1f01). Run sudo modprobe rndis_host |
3. Windows Setup (7, 8, 10, 11)
