Is it possible to unite all factions?

[Spall]

I just want to know if I can save all the factions, I like the Institute. Can I ally all of them together or is that a no?

[Khorne Flakes]

I think the best you can do is keep amiable relations with both the Railroad and Brotherhood as the minutemen. However, the Institute, Railroad, and Brotherhood cannot coexist together should you go down one of there paths.

There IS a way to have the Brotherhood, Railroad and Minutemen unite under peace, but it's (in my opinion) the hardest ending to get.
There's a discussion for it here:

If you get epilogue restored from nexus you can also be the sentinel of the Brotherhood, as well as General of the MM and lead agent in the RR. While completing the MM ending.

That's not entirely true. That freezes the quests at a point right before the RR or BOS kill each other. It even says "Don't talk to P.A.M. because she will start a war with the BOS." Which means there's technically more questing left that you're avoiding doing by keeping amicable relations between them.

to answer the OP, no.

Not in the game's current form. At best you can save 3, at worst 2 (I am pretty sure no one destroys the MM).

[fauxpas]

Yeah, abandoning the plot isn't the same as ending the story. So no, you can only save two factions by finishing FO(4); the Minutemen + One.

I had a great screw-over-my-faction-reputation moment, when I had to go to Bunker hill to reclaim synths. As planned, the Railroad was there to fight back, but then a Vertibird flies past and starts to engage the settlement. The Knights and Commander inside jump out and start shooting both the Railroad and the Institute, and I then have to decide between murdering my Synth allies, turning on the Railroad (who I've done many missions for), or killing fellow Humans.

I decide to kill my mission allies and the Railroad with help of the Brotherhood, besides I wouldn't want to fight eight suits of power armor, holding miniguns, laser miniguns and laser rifles, each with a zealous soldier inside.

This happened after I made this post, and I guess having to murder your allies and long time standing allies to save your other long time allies is the reason I want to unite all the factions.
Because I can't pick sides.

I finished the game as sentinel (BOS) and general of MM. I am satisfied.

Not without a mod that adds that option.

Basically if play as MM then only the institute would be destroyed unless you become hostile to the bos then you would have to destroy them.

There is instructions for a peaceful playthrough that lets you be members of all three factions so long as you do not progress the main story quest past certain points using the RR or Bos but it still requires the institute be destroyed. So basically if you want to actually finish the main quest or have everyone be friends currently no it is not one of the games vanillia options.

Personally I think it would have made a nice extra ending possibility if you could have brokered some sort of peace agreement between the factions especially after you supposedly were in charge of the institute.

Of course it would require the currant Bos leadership to be replaced and an agreement with the RR to stop using the gen 3 synths as if they were just machines instead of DNA based identical biological copies of humans essentially "printed" using biological material on a massive 3d printer.

at least that is the process I am reminded of when watching the machine in the institute creating one.

Thier is a trick to getting, BOS, RR and Minuteman all to like you if you do the missions in the correct order, but all 4 of them is impossible, I got banned from instatute with no way around it.

Nope, because as has been stated already, that "trick" is simply abandoning the plot and choosing not to advance the story to its conclusion, which is not an ending.

actually you can advance the story to the end with this trick, You will get a quest that a conflict is happening and if you notify the opposite faction they won't be your enemy.

You're not understanding.

Even after the "Ending" you'll have left over the option for either faction to overcome the other. You're willfully not completing available quests.

The MAIN quest is completed once the institute is blown up there is no left over missions to do this once it is gone.

In fact there is actually dialogue with the bos faction commenting on you using the MM to do the attack instead of them.

Technically, the Minutemen never get entirely wiped out, and neither do the Brotherhood (since they've got forces outside the Commonwealth); only the Institute and Railroad can be properly destroyed.

Though if you went with the Railroad, you could leave the Minutemen entirely alone (effectively nonexistent as a real force), wipe out the Brotherhood and Institute (which would at least end them locally), and then kill the Railroad yourself. That would leave all four factions united in being effectively dead.
