, particularly if it is done to hide a stolen device. While some argue there is nothing inherently illegal
The Fibocom L850GL is a popular cellular module used in a wide range of applications, from IoT devices to industrial routers. One of the key features of this module is its ability to support multiple frequency bands and networks, making it a versatile solution for developers and manufacturers. However, there may be situations where you need to change the IMEI (International Mobile Equipment Identity) of your Fibocom L850GL module. In this article, we will explore the reasons for changing the IMEI, the process of doing so, and the potential risks and considerations involved.
The modified and resigned NVM file is written back to the flash memory of the module using the Intel Download Port. 5. Troubleshooting Common Verification Issues

Technical Deep Dive: Modifying the IMEI on Fibocom L850-GL Fibocom L850-GL is a high-performance LTE Cat9 module based on the Intel XMM7360
: The modem can operate in different modes, such as MBIM (common for Windows) and NCM (common for routers). Technical scripts for IMEI modification often require the modem to be in a specific diagnostic or NCM mode to communicate properly. Methods and Tools
Under the Mobile Device Theft Prevention Act, altering or removing an IMEI number is illegal and carries federal penalties. , particularly if it is done to hide a stolen device
This action can lead to criminal charges, fines, and confiscation of equipment.
To switch or expose the module's diagnostic or AT command interfaces (often labeled as "Intel XMM7360 AT Port" or "Modem Port" in the OS Device Manager). 2. Terminal Software Configuration
Changing the IMEI on a Fibocom L850-GL is generally performed using specific through a terminal or specialized software tools, though it is important to note that this is illegal in many jurisdictions and can risk "bricking" the modem. Common Methods xmm7360/xmm7360-usb-modeswitch: Tools for the ... - GitHub However, there may be situations where you need
: In countries like the UK, the Cellular Phones (Reprogramming) Act makes it an offense to change an IMEI or possess the tools to do so. In the US, the FCC enforces strict equipment authorization guidelines. Altering a device's identity can violate carrier terms of service and federal regulations.
This architectural difference is critical. Qualcomm-based modules often utilize specific diagnostic tools (like QPST/QXDM) to read and write NV item data. Intel chipsets handle configuration parameters, calibration data, and identity structures through entirely different firmware architectures, typically relying on secured AT command interfaces or proprietary Intel flashing utilities.

Cellular carriers track IMEIs to whitelist approved devices and blacklist stolen hardware. Mismatched or duplicated IMEIs can result in immediate SIM card suspension or permanent network blacklisting.
