Regardless of what method that you use, BE SURE that you praise her EVERY time that you get her and she is close to you. Even if you have to reel her in with the long line, praise and toys and treats to her - EVERY TIME>
Even if it kills you because she wouldn't come when called!!!!!!!
BTW - I would also use the COME command outside - just do it in other places in the yard, not just by the door. I.E. call her when you are in the middle of the yard - she comes (however) and you praise her and/or toys and/or treats - then the big reward - let her go and play some more so she doesn't associate Come with "Funs over"
This worked VERY well with my sometimes reluctant recall.
