A firmware update system includes firmware storage device(s), an operating system engine coupled to the firmware storage device(s), and a remote access controller device coupled to the firmware storage device(s) and the operating system engine. The remote access controller device receives a single out-of-band firmware update command and, in response, performs a firmware storage device unlock operation to unlock the firmware storage device(s), transmits a firmware update package including a firmware update utility and a firmware update image to the operating system engine to cause the operating system engine to utilize the firmware update utility to update firmware stored in the firmware storage device(s) that was unlocked with the firmware update image and, subsequent to the operating system engine updating the firmware stored in the at least one firmware storage device that was unlocked, performs a firmware storage device lock operation to lock the firmware storage device(s).
