I have this phone, it is rooted.
I backed up the systemui which total size is smaller than 5mb then I uninstalled it using titanium backup then a message appeared "unfortunately systemui has stopped working" so I tried to restore it with TB but takes too much time (waited 20 minutes but still restoring).
I restarted the phone then the message still shows and its a black screen in the background... I tap "ok" and the message disappear a few moments but shows again and again.
Then I did a factory reset but the message "unfortunately systemui has stopped working" still showing with a black screen in the background.
How will bring back this systemui? is it possible with adb?
