The Fibocom L850-GL is an Intel XMM7360-based M.2 modem commonly used in enterprise laptops like the Lenovo ThinkPad. Unlike older modems that sometimes allowed simple AT command updates, modern modules like the L850-GL store the International Mobile Equipment Identity (IMEI) in protected, non-volatile RAM (NVRAM) or within a "One-Time Programmable" (OTP) section of the hardware. Older firmware (pre-2020): Change is possible via AT

  • Older firmware (pre-2020): Change is possible via AT commands or QC (Qualcomm) tools.
  • Newer firmware (2021+): Write protection is enabled. Attempts either fail or brick the module.

USB Mode Switching: In Linux, the L850-GL often defaults to PCIe mode, which is harder to interact with. Tools like xmm7360-usb-modeswitch can flip the modem into USB mode, allowing standard MBIM or AT command interactions.
