An attempt to flash the firmware in the controller results in error, "The UPREV code could not communicate with the specified controller."
Uprev operation attempted using the wrong flash file.
Re-try the operation using the flash file that matches the model number in the controller.
Note that regardless of what the model number reads from the InfinityController editor in CyberStation, the verification is done at the controller level. Do not go by what you see in the CyberStation as this user configured field could have been entered incorrectly. Verify the model number from the controller's web page configuration.
