I did ED-E's quest gave him to the followers and when he came back his laser did not work but, that's not the problem.

The problem is he got lost and after 3 days of playing, it said he returned to Primm and when I went to get him he was hostile, is there a way to fix it on the X-BOX 360.

Sorry if this has already been asked before, I used the search bar and could not find anything.
