回去回来 回来回去 来来回回 来来去去 Are they the same?
Personally I have never heard of 回去回来 or 回来回去, and they are highly unlikely to be idioms in any part of China. 

We do say 来回来去 in Northern China, not sure about Southern China. It means 'back and forth; repeatedly'. E.g.


他自从丢了钱包，就来回来去的说。He was complaining over and over again since he lost his wallet.
整首歌来回来去就一句词。The entire lyrics are just one sentence going back and forth.
