Is there a com.perverteer.tftuv2 in the RenPy_Saves directory in your Documents folder? If the saved games are still in the Android/App/Game the process won't work, unfortunately.
Could you perhaps post a screenshot of the file listing inside com.perverteer.tftuv2?
I'm not sure if you've already done so, but you should install the very latest version of Season 1 and run it at least once. If you've uninstalled the first season it might have deleted the saved games in Android/App/Game though, but it should at the very least create the com.perverteer.tftuv folder.
