David Martindale "knew" his Livingston would recover from two down as they secured an immediate return to the Scottish Premiership with victory over Ross County in the play-off final.
With the tie level at 1-1 from Thursday's first leg, County looked set to retain their top-flight status as Josh Nisbet and Ronan Hale netted in Dingwall.
However, an astonishing fightback started when Lewis Smith evaded three defenders to score.
Danny Wilson nodded Livi level and Robbie Muirhead curled in superbly from wide right to give Martindale's side the aggregate lead before Tete Yengi lashed in to make it 5-3 deep in added time.
"The players showed personality, they showed character," said Martindale.
"At 2-0 I knew we'd come back, I just had a feeling we'd win the game. At half-time I said to the players, 'go and get the next goal and you will win this game'. Robbie Muirhead comes up with a massive finish, and Tete with the fourth.
"That was my players out on the park tonight and I'm so proud of them."
Livi return to the Premiership a year after relegation and Martindale and the club recently announced Calvin Ford as their new majority shareholder, with Ford vowing to get the club "back to where they belong".
And Martindale said: "I owe Calvin Ford, he re-energised me. He gave me new impetus, new energy. He said they're going to put a new park down even if we don't go back to the Premiership."
Don Cowie's County, meanwhile, will be back in the Championship after six years in the top flight.
