I believe that the files you transfered via Bluetooth should be in:
InternalStorage\Bluetooth
but, depending on your phone it might be different. I can't say for sure that you will find them there.
You can download and install the game on your new phone. Once you finish installing it and once you find the files that you transfered to your new phone, move them to the same directory on your new phone where the game keeps the saves:
InternalStorage\Android\Data\0011\Org.HHGv012.0011
If there are already files with the same name in that directory you might get a prompt to replace the files with the new ones. If that's the case, confirm that you want to do that.
