I don't get it how to install and what should I download I use non-roted divise
Just read the 1000 Spoilers in every Thread which explain everything buddy.
We have everything which you need to know descriped on this Page.
Signed = for non rooted Device, you can't login into Google Play with it, you can't make in App purchases with real money, you can't overwrite old Mod Versions with it.
Unsigned = for rooted + patched Device, you can login into Google Play with it, you can make in App purchases with real money, you can overwrite old Mod Versions with it.
So you have to download the signed Mod Version when you have a non-rooted Device.
And after that you have to follow the Instructions which are written vor each mod in their Mod Threads.
You have a big red note in the Mod Description:
1. In order to run this App you will need to
grant storage permission and
overlay permission for that app if you have Android 6 or higher (some devices require contact permissions as well). Otherwise
it will crash cause of the menu!
2. If you see the menu icon double, force close the game. App Info -> Force Stop. The menu didn't closed correctly on last use.
It's not that hard
