Abstract
Technologies for remote firmware updates include a telematics cloud server in communication with multiple telematics devices. The server stores a compressed firmware package and a firmware manifest and firmware components from the firmware package. A telematics device sends a status update to the server and receives an acknowledgment that identifies an available firmware release. The telematics device downloads the firmware manifest, and for each firmware component, determines whether to update the firmware component. The firmware component may be a base install or a differential install. The server may flag the firmware component for a forced install. The telematics device may evaluate a device policy or an advanced rule to determine whether to update the firmware. The telematics device may evaluate a machine learning risk model to determine whether to update the firmware. Other embodiments are described and claimed.
