There are two files to download, one is the signed APK and the other is an OBB file. After download, put the signed APK in the download folder and the OBB file in the Android/obb folder on my phone.
I upgraded my account on blackmod.net to a VIP one so I can have all 12 mod options at once. I put the license.pm file in the download folder as well. I then deleted the original game and the Facebook app. It is important to uninstall the Facebook app, otherwise, the game will try to sign into my account through the Facebook app which throughs an error.
Open the game the first time and found a newly created folder named PLATINMODS.COM. The ON/OFF editable text file is in this folder. It really works!
