How to downgrade from 5.0 to 4.4.4?

I had 4.4.4 jailbroken with ATV Flash 1.4 with backup up saved. I’m not liking the 5.0 and want to downgrade. Not sure how and what the process is. i can get into maintance tab see the 4.4.4 save just not sure what to do from there. If i use the atv flash black to downgrade will it be jailbroken or do I have to re JB it?
