Jan 28, 2026 - Author: Sierra Wireless - Version 1 - 201 Views

WP76xx Release 17.1 is a maintenance release that delivers critical security patches, bug fixes, and stability improvements to enhance system reliability.

 

WP76xx firmware is available:

  • As pre-built images ready for installation on Windows or Linux hosts. See Installing Firmware Release 17.1 Updates, below.
  • As separate components for developers that wish to build custom Linux Distribution or Base Legato System images.
    See WP76xx Firmware Release 17.1 Components to create custom firmware packages.

Important note for the 2-stage AV FOTA firmware upgrade:

  • All legacy firmware releases can only be upgraded by AV FOTA to the latest version via Firmware 16.3. The AV FOTA process to intermediate Firmware Release 16.3 must firstly be completed before proceeding to the AV FOTA process of upgrading to Firmware Release 17 and later versions such as Firmware Release 17.1.
  • No firmware downgrade back to prior firmware releases is allowed once the firmware is upgraded to Release 17.1.
