This invention relates generally to methods and computer readable media for upgrading firmware stored in a non-volatile memory, in phases, and restoring firmware in-situ to compensate for failed firmware upgrades. In various embodiments, methods and computer readable media can upgrade and restore the firmware as the non-volatile memory remains functioning. In one embodiment, a method includes designating a first copy of firmware for accessing, and designating a second copy of the firmware for upgrading. The method continues by accessing one or more firmware instructions from the first copy. It also can include upgrading at least a portion of the second copy with at least a portion of new firmware. Upgrading the second copy can be coincident or substantially coincident to accessing the one or more firmware instructions in the first copy.
