How to Login Google Account Using Mod Apk:
1. Download apk from Ps (original) and Google playgames.
2. Open the game then login to your Google account (Make sure it is linked to your Google PlayGames account) *don't play it first*.
3. Exit the game, then go to file > android > data > "com.netmarble.nanarise" rename the file to "com.netmarble.nanarise00" up to you.
4. Delete apk from ps (original) then install mod/cheat.
5. Go to file > android > data, then find the previous file and change it back to the original file name "com.netmarble.nanarise00" > "com.netmarble.nanarise"
6. Open the apk, give permission then immediately exit the game (don't play it yet).
7. Go to settings > application details > select SevenDeadly Sins Idle Adventure > then delete all data from the game "Seven Deadly Sins Idle Adventure".
8. Then you can play and can log in to your Google account.
