adb backup and adb restore
So I want to root my Nexus 4. Do full backup using adb, root it, and restore it... but failed. And my data almost gone :( Before doing this, you must enable Developer mode, Enable USB debugging, install ADB on your laptop. To backup: adb backup -f backup.ab -apk -shared -all -nosystem #add -nosystem for unrooted device or will hang Then root your device: #please find tutorial elsewhere Reboot your phone, say no to all question, enable USB debugging again Reboot your phone, add all google accounts, install all purchased app. Before restoring, enable Airplane mode, Stop all possible task from Settings - Apps - Running Open other console to monitor restore progress, run adb logcat Now restoring, adb restore backup.ab #unlock phone and click Restore #wait until no other progress (watch on other console) #reboot, Ctrl-C and try to repeat restore until restored normally #restoring shared data will take long time UPDATE: Use my script to backup all apps to separate
