I would like to set my brothers Xbox account as my Xbox so we can share our games again.

If he's already reached his limit, he can try contacting support to see if they can reset it, but there are no guarantees. 1-800-4my-xbox if your'e in the US/Canada or http://support.xbox.com/contact-us

My brother and his xbox doesnt live with me. So he will have his xbox set to home, while i will have my xbox one s downstairs set to home, everything fine.

That would mean you are not sharing any games with each other. You would have to set his console as your Home in order to share and he would have to set one of your consoles to his Home in order to share. Any games you purchase on your account can be playing
on any console as long as you are signed into Live. Any games your brother bought you can only play on his Home console.

So me and my dad have seperate xboxs his is a X and mine is an OG but we want to share game pass but he doesnt want to change his home xbox.

We are also set up to his account and my account are on my OG xbox, but only his account is on his X, if i put my profile on there and set it as my home xbox can we share games? Or will it still not work.

Any way we can share games?

The process of "game sharing" is an interesting one, and one that involves a certain level of trust. The only way that I personally know of to share games on Xbox is through the process that you referenced in your post.

Your Father would have to log in on your Xbox and set your system to his home system.

OP would have to log in to Father's Xbox, and set OP's home console as his father's.

Then just go about your lives. That's how my wife and I have setup our home network, and have had no issues for 2+ years.

i have a similar problem i have xbox live and so does my brother and my brothers and mine account on my xbox one say that i don't have live and tells me to upgrade my and his account to gold but when we sign in to our oldest brothers xbox one (he moved out
but we like to visit) we do have live and we can do everything and we don't get asked to upgrade to gold please help me

You can add the subscription to one of their account. The one with the subscription would then set the console of the other brother as their Home console in order to share the subscription with them. They can then sign in and use their subscription on their
own console. https://beta.support.xbox.com/help/hardware-network/console/my-home-xbox

Things to keep in mind are that Game Pass itself does not share, but the games downloaded from it do. So the brother who has the subscription on their account would have to start the game downloads on their account, and then the brother without the subscription
can access the game.
