I would assume They have it backed up through a wireless terminal, if not I suppose you could save the whole file on your desktop...???
Edit: Backed up sd-ext data???

 

I would do a app+data backup with Titanium Backup for Angry Birds, that should do the trick... :thumbup:

 

If it was completely stock then chances are your data was stored on your internal memory. If that's the case then there is no way of recovering it. If you had /data to SD or other such modifications to your stock then there may be a way of recovering it. Not everything is stored on the SD cards when it comes to regular stock. This includes saved games.

The only true solution to backing up game files is using an app to do it. Sure you can do it manually but you may miss some stuff.

Titanium Backup has the ability to backup and restore app /data. This app is a life saver when it comes to these things. It's a must have app at least for me on any of my rooted devices.

There are alternatives you can use that do the same thing.

1. Fast Uninstaller & Backup
2. Root Uninstaller (don't let the name fool you it also backups)
3. MyBackup
4. GoBackup (from the creators of GoSMS and GoLauncher)
5. ES File Explorer (In ES Explorer, click on AppMgr on the toolbar, Select your apps and hit back up.)
6. much much more but you have to google it yourself

Would like to note even with all these alternatives, hands down the best one is Titanium Backup. It really is worth the money.

 

I change ROMs quite a bit so whenever I flash one thats not compatible with my backup I usually re-download apps from the play store and then restore data only with Titanium. It only works with user apps it won't work with "accounts" or "wifi" settings etc
SMS backup + will restore call log and messages

 

Lol or you could use one of the level unlockers for root from the play store
