I apologize, in my comment I said that I could login with Google, I forgot, it turns out the device I'm using is rooted so the Google and Nintendo login options work. And I haven't tried using a non-rooted device, Because I use titanium backup to store many rerroll accounts.
Well, there is no mod menu, when installing the game it seems accelerated, however, I still have to wait 11 hours to open a pack, so it seems to me that this mod is only for reroll and not to help open more packs. But I could be wrong.
