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!
Answer
Another fool-proof method (no need to worry about having a specific backup app) is to grab the game's data directly.
The data for all user-installed apps can be found in /data/data/*package name*. This will be all settings, saves, and anything else. Just browse into there and copy the relevant directories to somewhere safe and put them back when you're done flashing and have reinstalled the app and run it at least once.
Yet another way, which will work without root, is you do the same as above, but using adb. Turn on USB debugging, connect up to your computer, and run adb pull /data/data/*package name* C:\where\you\want\the\files.
Then once you're done with your ROM flashing and have reinstalled the apps, do adb push C:\where\you\put\the\files /data/data/*package name*, or if you now have root with your custom ROM, just copy the directories you pulled to the SD card and put them back in /data/data on the device.
