This mod is amazing thank you. Is it possible to make an unsigned apk to allow google log in? I tried myself but can't get it working. And with mod it always makes a new account, cabt get my original account. Thank you
Download the original game and login to your main account, after that backup the data only.
Delete the original game and install the mod, restore the data and you'll get to play with your main account.
I managed to do it but i don't know if it'll sync with google play account because there's no longer a little pop up at the top of the screen when logging in
I used Swift Backup but it should be possible with any tools that can backup apk's data, ohh and you need ROOT probably, to backup data
