First , You need a file manager (Example . ES FILE MANAGER) Then you download this pp.dat https://docs.google.com/file/d/0Bz50SD5XrLlWRFRCbnBHOXN5NXc/edit?pli=1
After downloaded , Replace your original pp.dat in " No backup " with it and go look for Update your pvz2 to 2.7.1 After everything done , You might notice you got lots of coins , Gems , And all plants and costumes unlocked.
Now , For get the bowling bulbs and the beach plants , You gotta edit sightly your game. Get hex editor (HEX EDITOR is for android , HXD editor is other thing) Then open your obbfile. (If requested imma put the order for get to it) And search in ASCII " LILYPAD " The way you see it. Later you will find " Beach " below it , And some numbers. Change the very first numbers on beach. You have to change them to " 65 67 79 70 74 " If you done right , Beach will be replaced to egypt. However this works only when combined with the PP.DAT
That's it , All credit goes to trevor angry. I just shared his knowledge. Have fun! (This method not gives you fire pea , Marigold )
