ScireM finaly fix problems on 5.1.0, it say 5.1.0 boots into atmosphere and version 1.0.0/2.0.0 can boot into exosphere. I don't know if 5.x.x can boot into exosphere like 1.0.0/2.0.0. But if you have this versions (1.0.0/2.0.0) feel free to test atmosphere, you won't get problems like sleep mode (I envy you )
