Abstract
Systems and methods for updating firmware include a firmware update module executing on a client device. A firmware package to be installed on the client device may be verified by the firmware update module, including verifying that firmware files included in the firmware package are intact prior to beginning a firmware update. Recovery logic for enabling a client device to boot-up from a functional partition after a failed firmware update may be provided. The recovery logic may ensure that, when a firmware update failure occurs, the client device may boot-up from a functional partition. A recovery process may back up certain components stored in the client device. An update status related to the firmware update process may be provided.
