Risk: Flashing firmware carries a risk of bricking your device. Proceed carefully and ensure your PC has a stable power supply.

Backup: Unlocking may reset your settings. Note down any custom APN or Wi-Fi configurations before starting.

IMEI: You will need your device’s IMEI number, usually found on the sticker under the modem cover or on the device packaging. Step-by-Step Unlocking Guide 1. Prepare Your Hardware and PC Unplug the modem from your PC.

Insert a non-provider SIM card (e.g., if it's a Telstra modem, use a Vodafone or Optus SIM).

Uninstall any existing modem software (like "Telstra 4G USB+WiFi Plus") from your PC and restart. 2. Obtain Necessary Codes

You will need a Flash Code to authorize the firmware change:

Use a Huawei Flash Code generator and enter your device's IMEI to get the code. Save this code for the flashing step below. 3. Install Drivers and Preparation Tools

To allow your computer to communicate with the modem during the unlock process, download and install:

Huawei Serial & COM Port Drivers: FcSerialDrv.rar and Huawei_Drivers.rar.

DC-Unlocker: Used to verify the modem's lock status. Download the DC-Unlocker client. 4. Downgrade the Firmware Most modern E8372h-608 Customization : By unlocking the firmware, developers can

firmware versions block direct unlocking. You must flash an older version:

Download the Downgrade Firmware: E8372_firmware_downgrade.7z. Connect the modem directly to a USB port (avoid hubs).

Run the update executable (e.g., P711s-WINGLE_Update_21.110.99.04.00.exe). When prompted, enter the Flash Code you generated earlier. 5. Perform the Unlock Open DC-Unlocker as an administrator.

Select "Huawei Modems" and click the Magnifying Glass icon to detect your device.

Verify the SIM lock status. Once the downgrade is successful, the device should report as "Unlocked" or allow you to enter an unlock code via AT commands. 6. Update to Universal Firmware (Optional but Recommended)

Q4: My dongle says "locked" even after firmware flash. Why?

You did not fully flash. Try again using a different version (e.g., 22.200.xx.xx). Also, ensure you removed the SIM before flashing.

What is "Unlock Firmware"?

"Unlock firmware" is a generic, unbranded software package that replaces the carrier-specific OS on your dongle. Unlike a simple unlock code (which only removes the SIM restriction), unlock firmware achieves three things:

  1. Permanent SIM Unlock: It removes the network lock entirely.
  2. Debranding: It removes the carrier logo and startup screen.
  3. Full Feature Access: It enables hidden menus (e.g., band locking, SMS settings, advanced network selection).
  4. Firmware Update: It upgrades your device to the latest stable HiLink or WebUI interface.

Key distinction: You do not need a paid "unlock code" if you use unlock firmware. The firmware bypasses the lock mechanism completely.

Why Unlock the E8372h-608?

Out of the box, carrier-locked E8372h-608 devices have three major limitations:

  1. SIM Network Lock (SIM Lock): The device only accepts SIM cards from the original carrier. Inserting a different provider's SIM results in an "Invalid SIM" or "SIM Lock" error.
  2. Band Restrictions: Carriers often disable specific LTE frequency bands to prevent the device from roaming onto competitors' networks, reducing performance.
  3. Feature Limiting: The web interface (usually 192.168.8.1) may hide advanced settings such as band selection, manual APN editing, or SMS controls.

Unlock firmware removes these barriers, turning a single-carrier stick into a global 4G modem.

Step 3: Enter Download Mode

  1. Remove the SIM card and SD card from the dongle.
  2. Press and hold the WPS/Reset button (tiny hole or side button).
  3. While holding, plug the dongle into your PC’s USB port.
  4. Continue holding for 10 seconds.
  5. Release. The LED should blink red/blue slowly. The device is now in "Download mode."

Part 2: Identifying Your Exact E8372h-608 Model

Before proceeding, you must confirm your device is the E8372h-608 (not the E8372h-153, E8372h-155, or E8372h-609). The "-608" suffix is critical.
