Not sure if this is known, but I just figured out something to restore progress on angrybirds. You can back up with titanium backup, but it didnt restore the data when I did that. My girl is on 11.19 build and I am trying to convince her to update, but she doesnt want to lose progress on angry birds. BUT....I figured out how to "highjack" her progress lol...since I lost all of mine on a flash and didnt bother restoring it. Heres the steps. This also works for saving someone elses progress as your own. I did it to mine. 1. Before you flash, use root explorer and go to /data/data/com.rovio.angrybirds/files and copy the highscores.lua file. Move it to your /SD card. 2. Wipe your phone...install new version of MIUI (or whatever you install) 3. Boot up and download angrybirds from the market again. 4. MUST DO THIS STEP!!! Open angrybirds and beat level 1. Shouldnt be too hard...its one bird kill. 5. Close app and go to /sdcard/highscores.lua Copy the file to /data/data/com.rovio.angrybirds/files...and overwrite the existing highscores file. BAM...progress restored....or progress upgrade to someone elses progress using the same method.
