Dean Sturridge scored twice and it was soon three after an Aljosa Asanovic penalty.
Leeds began to click into gear as the first half progressed.
A stunning volley from Harry Kewell gave Leeds a lifeline and Rod Wallace was in place to score and end the half at 3-2.
The second half started as the first ended, with Leeds on the attack.
Jimmy Floyd Hasselbaink equalised from the penalty spot and then in stoppage time the Dutch forward evaded the County defence.
He calmly pulled the ball back to Lee Bowyer to finish and complete the comeback, giving Leeds a 4-3 victory.
