I've seen how to get Synth Shaun as a settler with the Institute and Brotherhood ending, however I was wondering if it's still possible to get him if I side with the Railroad/Minutemen. If so how would I go about doing it?

How do you get him as a Settler in the Institute ending?

You can find him in the Advanced Tech area I believe. Then can move him to a settlement through dialogue. I haven't tried this only seen it in a video

Do you happen to have a link to said video?

I'm intrigued because he just ask for random junk in my game. Would be nice to be able to move him.

Agreed.

I'll have to look for it, if you say it can't be done I would have to say I must have got it wrong or they used some sort of mod/glitch

It is. When you are blowing up the Institute you'll find him at the end and have the option to take him with you.

Do I have to talk to him before then? According to the wikia if he's inside the institute when it's destroyed then he won't appear for the rest of the game

Yup, you have the option in dialogue of taking him with you. He says he needs nothing else from you but it might bew possible with further dialogue to get him as a settler. I just left him to the nuke.

same here. he wants a clock.

I'd rather send him to live with Curia and I over at Kingsport Lighthouse.
