Unfortunately on any mobile device the boosters are lost once you change your phone or uninstall and reinstall the game. The only thing that is saved are the gold bars. You can't get them back and I remember being told to use them as I need them because once I do what you did the boosters are gone. Sorry for the negative answer but that is a downside to using a mobile device.
