Age is 16-17. No crews in the district at this time. As to transferring to another troop, I do not see that as a option as this is the troop that has issues with everyone else (I found out it's not just my troop and me the SM doesn't like, but I am public enemy #1 for him).
A boy's transfer has nothing to do with his previous troop. If there's an SM who will have the kid, and someone ponies up the $1 and the paperwork, it's a done deal.
The EBoR is a done deal. National is probably already processing the paperwork. Your council registrar should make a few phone calls explaining the situation just to be sure this boy's recognition won't be held up by some poor management.
The reason for the transfer is to get the scout out of a toxic situation and into the hands of someone who will responsibly handle any materials that come his way. This sounds like a boy who has been isolated from council, and doesn't have any "friends in high places" like a lodge advisor. So, he needs to know that someone he can relate to has his back ... maybe someone who will help him exercise some more leadership and work toward a palm or two.
This allows the original SM time to focus on getting his charter together without worrying about this scouts bling floating around in some bureaucratic nether-world.
This is important, because if you all can't get this SM back on track, you'll have a troop full of boys to deal with. For anything but Eagle, the essential paperwork is backed up in the boys' books. So if the boys know you didn't let Eagle paperwork slip, they can be confident that you'll keep their advancement on track if they have to jump troops to maintain their registration.
I wish someone told my brother this when his SM went AWOL 60 years ago. The thought of hoofing over to the troop on the other side of town to ask a different SM to help him wrap up his trail to Eagle was completely foreign to him.
