If you stumble upon a “magic software” on a shady forum promising one-click IMEI change, it is likely malware. Many such tools for the L850-GL contain keyloggers or ransomware. Always research thoroughly.
This article is for educational purposes. Modifying your device’s IMEI may violate local laws. The author assumes no liability for any damage, legal action, or loss of connectivity resulting from the information provided.
Changing the IMEI on a Fibocom L850-GL (an Intel-based LTE M.2 module) is generally not possible through standard software or simple AT commands because it is hardware-locked by the manufacturer to prevent tampering.
While you can interact with the card using specialized tools, here is the reality of trying to "work" on its IMEI: 1. AT Command Limitations
Standard Intel/Fibocom AT commands like AT+EGMR (often used on MediaTek devices) do not work on the L850-GL. Most commands that might access security parameters are protected by manufacturer-level passwords or "Engineering Mode" access that is not publicly available. 2. Specialized Software (Difficult)
Some advanced cellular repair tools (like ChimeraTool or Miracle Box) may support IMEI repair for certain Intel chipsets, but the L850-GL is notably difficult because it uses a specific XMM7360 modem firmware that is highly secure.
ChimeraTool often requires the device to be in a specific "Flash" or "Boot" mode to write to the NVRAM.
Even with these tools, success is rare on this specific module without proprietary Fibocom flashing tools. 3. Legal and Practical Risks
Legality: Changing an IMEI is illegal in many jurisdictions, including the US, UK, and EU, as it is often associated with bypassing blacklists for stolen devices.
Bricking: Attempting to force a write to the modem’s firmware can easily "brick" the module, rendering it unable to connect to any network or even be recognized by your laptop. 4. Better Alternatives
If you are trying to "work" the card because it isn't connecting:
Update Firmware: Ensure you are using the latest firmware from your laptop manufacturer (e.g., Lenovo or HP), as these modules often have compatibility issues with generic Windows drivers.
Check Carrier Compatibility: The L850-GL is a Category 9 modem; ensure your carrier supports its specific LTE bands.
Are you trying to bypass a network lock or fix a device that isn't being detected by your laptop?
Even though L850-GL uses an Intel baseband, some variants share Qualcomm-style NV storage. This method is more promising but dangerous.
On specialized forums (4pda, XDA Developers, GSMhosting), users have reported success using:
However, firmware updates from Lenovo/Dell frequently patch exploits, so a method that works on firmware version 1.0 may fail on 1.2.
