To change the IMEI on a Quectel modem, you typically use specific AT commands through a terminal interface. While Quectel does not officially document or support this feature for general users, it is often possible using the AT+EGMR command, which is frequently used for "repairing" or setting the identifier on modules like the EG25-G. Prerequisites & Installation

Before running commands, you need a way to communicate with the modem:

Drivers: Ensure you have the proper USB drivers installed for your OS to recognize the modem's diagnostic or serial ports.

Terminal Software: Use a serial terminal like Minicom, PuTTY, or QNavigator.

Modem Access: On Linux systems (like the PinePhone), you must often stop the modem-manager service first to prevent it from locking the serial port. Step-by-Step Procedure

Check Current IMEI:Open your terminal and verify the existing IMEI using:AT+GSN or AT+EGMR=0,7.

Apply New IMEI:Use the following command format to update the identifier:AT+EGMR=1,7,"YOUR_NEW_15_DIGIT_IMEI".

Verify the Change:Run AT+GSN again to confirm the modem reflects the new number.

Reboot the Modem:To ensure the change is persistent and active on the network, restart the device:AT+CFUN=1,1. Important Considerations

Legal Compliance: In many regions, changing an IMEI is illegal and can lead to network blacklisting or prosecution.

Official Support: Quectel representatives generally state that they do not provide commands for modification and cannot guarantee device stability afterward.

Integration: For advanced users, tools like the asterisk-chan-quectel driver on GitHub allow for complex call handling using specific IMEIs.

Device Specifics: On some Android-based devices, you may need root access and a terminal emulator to run AT+EGMR=1,10,"IMEI_NUMBER" instead.

Modifying the IMEI on Quectel modules is a common but sensitive procedure primarily used for "IMEI repair" or to bypass carrier restrictions. While technically possible through specific AT commands or third-party tools like DC-Unlocker, it is officially discouraged by Quectel and is illegal in many jurisdictions.

This report outlines the technical procedures, software requirements, and regulatory implications for modifying the International Mobile Equipment Identity (IMEI) on Quectel modules. 📋 Executive Summary

Modifying an IMEI (often termed "repairing" or "writing") on Quectel modules is primarily done using AT commands or proprietary Quectel tools like QFlash. While technically feasible for most LTE and 5G modules (e.g., EC25, EG25-G, EP06), the process is subject to strict legal restrictions in many jurisdictions and may void manufacturer warranties. 🛠️ Technical Procedure: AT Command Method

The most common method involves sending specific strings to the module's AT Port via a serial terminal (e.g., PuTTY, QCOM, or Minicom). 1. Identify the Correct Port Windows: Check Device Manager for "Quectel USB AT Port". Linux: Typically maps to /dev/ttyUSB2 or /dev/ttyUSB3. 2. Verify Current IMEI

Before making changes, document the original factory identifier: Command: AT+GSN or AT+CGSN=1. Response: Returns the current 15-digit IMEI. 3. Apply New IMEI Most modern Quectel modules use the +EGMR command. Command Structure: AT+EGMR=1,7,"[15-digit_IMEI]" Action: Open the serial tool at 115200 baud. Type the command with the new 15-digit number in quotes. Receive response OK.

Reboot: Execute AT+CFUN=1,1 to restart the module and apply the change. 💿 Software & Driver Installation

Changing the International Mobile Equipment Identity (IMEI) of a cellular module is a complex procedure often necessitated by regional regulations, network compatibility issues, or device testing requirements. When working with Quectel modules—such as the popular EC25, EP06, or RM500Q series—understanding how to "install" or reconfigure an IMEI requires a mix of specific hardware drivers, AT commands, and specialized software tools.

This guide provides a comprehensive overview of the process, the tools required, and the critical legal considerations involved. 1. Critical Legal and Ethical Warning

Before proceeding, it is vital to understand that changing an IMEI is illegal in many jurisdictions, including the United States (under the Mobile Device Theft Deterrence Act), the UK, and much of the EU. The IMEI is intended to be a unique, permanent identifier.

Authorized Use: This process should only be performed for legitimate development purposes, such as restoring an IMEI to a repaired board or testing private LTE/5G network authentication.

Unauthorized Use: Changing an IMEI to bypass blacklists or "unblock" stolen devices is a criminal offense in many regions. 2. Prerequisites for Installation

To interact with a Quectel module and modify its internal identity, you need a specific environment:

Quectel USB Drivers: You must install the official Quectel Windows/Linux USB drivers to expose the AT Port and the Diagnostic (DM) Port.

Hardware Interface: The module must be connected via a Mini PCIe to USB adapter, an M.2 to USB bridge, or a development evaluation board (EVB).

Terminal Software: Tools like QCOM (Quectel’s proprietary utility), Putty, or Tera Term are required to send commands.

Quectel QPST/QFlash: In some recovery scenarios, these tools are used to interact with the Qualcomm-based firmware layers. 3. The "Installation" Process: Step-by-Step Step A: Identify the Current State

Connect your module and open your terminal software. Select the Quectel AT Port (usually at 115200 baud). Check the current IMEI by typing: AT+GSN Use code with caution.

This confirms the module is communicating and displays the current 15-digit identifier. Step B: Entering Production/Engineering Mode

Quectel modules often require a "security password" or a specific command to unlock the write-protection on the IMEI field. Depending on the specific firmware version, you may need to use: AT+EGMR=1,7,"YOUR_NEW_15_DIGIT_IMEI" Use code with caution. Quectel is one of the world’s leading suppliers

Note: The 1,7 parameters specifically target the IMEI storage in the module's NVRAM. Step C: Verifying the Change

After sending the command, the module should return OK. To finalize the "installation" of the new identity, you must restart the module: AT+CFUN=1,1 Use code with caution.

Once the module reboots, run AT+GSN again to verify the new IMEI is active. 4. Troubleshooting Common Issues If the command returns ERROR, consider the following:

Locked Firmware: Some newer firmware versions (especially those sold to specific carriers) have the IMEI field "hard-fused." In these cases, standard AT commands will not work.

QCN Backup: Professional engineers often use the Quectel NV Item Manager to back up the QCN file. If an IMEI "install" fails, the QCN can be edited and reflown back into the module using QPST.

Driver Conflicts: Ensure that no other software (like Windows Modem Manager) is occupying the AT port while you are trying to send commands. 5. Summary Table: Required AT Commands AT+GSN Read current IMEI AT+CGSN Alternative read command AT+EGMR=1,7,"..." Write new IMEI to NVRAM AT+CFUN=1,1 Full hardware reset/reboot Conclusion

Configuring or "installing" a new IMEI on a Quectel module is a powerful capability used primarily in the IoT development and repair sectors. By using the correct Quectel USB drivers and the AT+EGMR command suite, developers can ensure their modules are correctly identified on private or specialized networks.
