It's not true (for me) I use Google login on an alt account only to sync with my real device when I don't need cheats. But it's true that cheating on a main account is gambling :)
1) In LP go to toolbox -> Android patch and apply the 3rd (disable signature check and allow downgrade) 2)Launch official apk, login to Google and download all data in "settings" (not sur if really needed) 3)Quit game, install the modded apk directly and enjoy :) If you are VIP launch BlackGame...
Works fine for me since 1.1.1. Using LDPlayer 3.92, used LuckyPatcher to install mod over official apk (for link my account with Google before) activated license with BlackMod Manager. Thank you @Mod4U
