To recover, perform the following:
• Go to http://www.rockwellautomation.com/support/
and download the firmware revision you are trying to upgrade.
Replace the firmware revision that you have previously installed with that posted on the Technical Support website.
• If the replacement firmware revision does not resolve the anomaly, contact Rockwell Automation Technical Support.
