Delete Facebook app from emulator, if you cant just enter in settings and disable it. After that enter in your browser and login in facebook. Then in game you chose facebook login method and it will open your browser because app is disabled(with app you will have error), and done. And if you tried unsigned and didn't work try with signed version.
P.S turn off antivirus before install and while use mod, because sometimes it didnt let me run the app and when I turn off it works.
N5-1 has enemies that receiving 0 damage even with all mods turned off, and my team has higher total power. Maybe someone can confirm for me whether this is personal or common problem?
