I lost my progress on PVZ2

All of your pvz 2 progress is stored in a file called pp.dat.

You can find this file in the directory /sdcard/Android/data/com.ea.game.pvz2_row/files/No_Backup.

Install pvz 2 (if you haven't) and don't worry about making progress just fetch for the pp.dat file of the app and copy paste it to a more accessible location.

Now go to your browser and search for a "pp.dat editor", select the page with your preferred language and slide to the bottom of the page, click "select file" and search for the pp.dat file you copied, once you select it you will click send, and from there you can adjust the values of the save file at how they were in your lost progress.

After you're done restoring your progress save it, (it will download a new pp.dat file with the progress you added).

Make sure the pvz 2 app is turned off, Now go to /sdcard/Android/data/com.ea.game.pvz2_row/files/No_Backup again and replace the old pp.dat with the new pp.dat you've just made.

And finally it's done, once you open pvz 2 again, your progress should be restored.
