There was previous logic in place to display a visual indicator for the status of the firmware flash using different colors for the progress bar. Unfortunately the logic was never working, or was broken at some point. The progress bar color would remain the default even if the flashing failed, making it difficult to recognize there was a problem.
Fixed to display the progress bar in green for success, red for failed, and blue for other "action required" types of failures. The logic was already there to try and display the red and blue indicators but they weren't working.
