My Mars 3 came with mars 3 pro firmware

I am having a hard time updating my mars 3. I bought it and it was delivered about a week ago. I was setting it up yesterday and I tried to update my firmware. I was greeted by long, loud, repeated beeps. It never allowed me to update. I checked my current firmware and it appears it arrived with the current Mars 3 Pro firmware. Is this going to prevent me from printing? How do I go back to regular Mars 3 firmware?
