Proper bleeding will never be done at first try. It usually takes 3-4 times in order to properly bleed it, simply because of trapped air.
To make this as simple as possible:
1. fill it up,
2. open bleeder screw, engine running, heater on hot and full blast, squeeze all the hoses you can reach, double check the coolant level,
3. drive around, make sure to go over bumps, hard stops - it helps.

And then you repeat steps 2-3 for at least 3 times and it seems to bleed it.
I just usually fill up, go to work, bleed. Come back home from work, bleed. Two three days of this and it works.

Also make sure you have no leaks.
