I was having APM 2.5 with my quadrotor. But it fall on the ground and its one motor is damaged. I am trying to stabilize it after loosing its one rotor. It is possible to fly it (a little bit) using auto tuned APM2.6.

Really? You're going to trust flying $800-$2000 worth of investments to a hacked up broken and bent motor instead of buying a new rather inexpensive motor??
My motor was not inexpensive, and the repair saved me from replacing it,
Of course I am playing it safe and I have a brand new motor when that one goes out, or a different one...
My "Hacked up broken motor" has so far 10 hours of hard quadding on it,
and probably could still out fly a new cheap motor because of the quality of design and repair.
If the goal is to stabilize with a broken motor, repair or replace would be the hardware solution.
If you know how to do it, why not.
Software solution
I've seen the failsafe video where it spins instead of flipping over or diving. Posted above.
I would like to have the spinning feature when a motor goes out, then at least it will land softy.
Even if you only have throttle control, that's enough to keep it from landing on someone.
I have had motors go out for different reasons, when everything seemed fine. Things like loose wires, loose mountings, or out-of-tune software, low battery, and in all of those scenarios, it has taken experienced piloting skills to bring it back down safely. It is possible to land a quad with 3 motors, but it is not safe and you need a lot of practice. And it doesn't look like landing it's more like a controlled crash.
I'm wondering....
If you keep the throttle low, and figure out which rotor went bad, and hold the yaw in the correct position, you can emulate the failsafe and keep it upright as it descends. is there a pilot that can do it.?
I'm just trying to help, sorry if you don't like my method or suggestions, better be different than all the same.
Then you need to buy another motor. There are no mainstream commercially available realistic existing flight controllers that will maintain flight with three motors on a quad. It is not possible or practical. You can ask the same question over and over, the answer will be the same.

Have you checked if the motor is repairable?
I crashed mine the other day and lost 2 magnets and I just had to clean the magnet fragments out.
It runs a little bit hotter but it flies no problem.
If you bent it maybe you need a little more effort...

No, you should buy a replacement motor for the one you broke. No flight controller is going to fly a quad with a failed motor.

Seriously??? Are you not actually reading anything. You cannot fly a quad with three motors using any version of Arducopter.
This is getting comical at this point.
I think the video you are looking for is this :
see it after 00:15 and you will see that no external computing is required or 3d live tracking system ;)
