Alternatively, using :
The modified binary is written back to the device. Because the Intel 7360 uses secure boot signatures, the modem may reject the file if it detects the modification, leading to an "Invalid SIM" or "No Service" error. ⚠️ Common Obstacles PCIe vs. USB
The Fibocom L850-GL is a high-performance LTE Cat-9 M.2 module used in many laptops, like the Lenovo ThinkPad series, and specialized routers. Users often look for a way to change the IMEI to fix "Sim Not Registered" issues or to use smartphone-only data plans.
Typical technical approaches (high-level) fibocom l850gl change imei work
: Changing the IMEI on a Fibocom L850-GL is possible if you have an older firmware revision and the right leaked tools. However, for most users, it does not “work” reliably due to security hardening, legal restrictions, and the risk of bricking.
The Fibocom L850-GL is a multi-mode LTE module based on the Intel XMM7360 chipset. It provides high-speed data transfer (up to 450 Mbps download) and operates on global LTE bands. Due to its architecture, it is frequently used in custom router builds using OpenWrt or similar systems. Can You Change the IMEI on a Fibocom L850-GL?
This is often done through a terminal or a router's management GUI. The most cited command is: AT+EGMR=1,7,"YOUR_NEW_IMEI" Alternatively, using : The modified binary is written

Certain firmware versions or engineering tools might temporarily spoof an identity in the volatile memory (RAM) of the modem.
: Community-driven projects like Fibocom-L860GL-IMEI-Changer provide scripts that may also work for the L850-GL due to shared architecture. Important Considerations USB The Fibocom L850-GL is a high-performance LTE Cat-9 M
Technical risks
: Specialized scripts like imei_tool.cmd are often used in conjunction with specific firmware versions.
Many tutorials on the internet describe how to edit a .qcn file using QPST (Qualcomm Product Support Tools) and then restore it to the modem. This works for devices based on chipsets. The Fibocom L850‑GL is NOT a Qualcomm device – it is built around the Intel XMM7360 platform. Therefore, QPST and similar Qualcomm‑only tools are completely irrelevant to this module.
There are a few methods to change the IMEI of a Fibocom L850-GL module:
