A safer bet would be to use the "remove factions" console command first. I don't remember exactly what it is, maybe "removefromallfactions", but in the console type: "help remove 0" and it should pop up. So basically its should go like this: either find or spawn an assaultron dominator(for console commands type "help assaultron 0", use page up until you see "assaultron dominator" then type "player.placeatme xxxxx" xxx being whatever the id numbers that come up are.) Exit the console and one will spawn next to you, but it will probably be hostile, so once you turn and face it, hit the console key ~ and click on the npc with your mouse while in 1st person. then type "tai" in the console to disable the ai. Also keep in mind, when you enter "tai" to have the correct npc selected or it will disable ALL ai in the game. With the NPC selected in the console, then type the remove factions command, then enter "help player 0", scroll up until you find the id for the player faction. Then enter "addfac xxxx" xxxx being whatever the player faction id is. Then enter "tai" again and exit the console. If the npc still attacks you, go back into the console and and enter "tai" again. then enter "stopcombat" and "setrelationshiprank player 4". Once you get the npc to stop attacking you, go back into the console, select the npc and enter "setconsolescopequest followers" then enter "forcerefintoalias dogmeatcompanion", then enter "setplayerteammate 1". That should hopefully do it, assuming I got the exact phrasing of all the commands correct. edit: keep in mind that assaultrons are dangerous followers. Their death ray attack might incinerate you if you're not careful.
