Cannot load an old farm to a new device

Hi,

My brother had a farm that he played a few years ago and he linked it to his facebook, I am not sure if he linked it to game center, then he quit. Today, we tried to recover the farm on an ipad, when I chose the higher level farm over the current level 1 farm, there was nothing happened. The screen stopped right at sign in with SC ID or playing without SC ID. Is there a way to recover the farm, and where can I contact SC to provide farm level and name?

Please help.

I didn't find the right solution from the Internet.
