Back up not only games, but also game progress before flashing ROMS I have a Galaxy S2 (GT-I9100) And I'm about to flash a custom rom on it. I've done it a bunch of times but what really irritates me is that I lose all progress made on the games that I have on my phone!

I backup the actual games and other applications using Astro file manager, but when I star my phone up after flashing a rom and re-install the game, I have lost all progress.

How does one backup a game, with game progress intact?

Thanks for any tips!
The best are backup methods that backup and restore app data. Titanium Backup is excellent for this, and easy to do, especially with the pro version. It allows you to backup the apps, including the relevant app data, which holds the game progress. The pro version lets you restore them seamlessly, while the free version requires manual re-install, like Astro. You can also sync these backups to online storage spaces like dropbox or Google Drive.

If you have multiple devices (I have a tablet and phone that I like to sync progress on, for example), DataSync is by far the best option. It can sync to dropbox or strictly device-to-device, but can sync all the app data with game progress to another device for subsequent use, or resyncing back to the original device later.
