EM/MC74x1 Approved FW Packages
- Dec 17, 2025
- Author: Sierra Wireless
- Version: 15
This page includes approved operator images comprised of FW and Configuration files. Packages are available for the EM7411, EM7421, EM7431, MC7411, MC7421, and MC7431.
This page also contains the latest recommended FW/PRI versions. To determine which FW/PRI are available in production for your module SKU, please check with your Semtech sales contact. Firmware is delivered in a zip file containing a CWE and NVU files that should be used in conjunction with the ‘Firmware_Download’ application (or equivalent APIs in an application) contained in the Linux SDK SampleApps.
The earlier releases have Windows EXE available, that will update both the PRI (carrier provisioning file) and the firmware. We stopped releasing Windows EXEs starting from 2024 onwards.
FW Release notes are available here.
