To everyone who's been having problems with downloading this mod, I'm really sorry but I honestly don't know how to help. I've downloaded this on a few devices and never had this problem. My only guess as to why it's not working is because the game cache is so big, there might not be enough room on your device and it fails to download properly. My advice would be, make sure you have at least 1gb of free space on your device before downloading this mod. I'm really sorry that I can't be of any more help.
