Okay so this should solve the black screen issue. The mod DOES WORK now. What happens is we're installing the game wrong. Download both the APK and OBB (doesn't matter which order). Next install the APK (BUT DON'T OPEN IT when it finishes installing). After that extract the OBB from the zip file into your OBB folder on your Android. Now go to your home screen and open the game. That fixed the black screen for me. Hope this helps! Also use the app ZArchive to extract the OBB zip file. I couldn't get it to extract correctly from just going into "Files".
I have a mod of this game from a different platform I want to download this one because they haven't updated their application to 5.1.1. My question is will I have to restart all over if I download this one or will the same data be on there?
