After rooting , I have uninstalled some important system app . My phone isn’t starting and even if it is starting once in a while I am not able to access anything. The notification- com.android.systemui has stopped- appears multiple times in a second . Due to that i am not able to do anything. I don’t have any backup too. How can i solve this problem ? I have tried methods such as hard reset , factory rest , flashing , installing custom ROM ,rebooting etc but to no Avail .My device is Gionee Pioneer P4 . But none of them have worked . Please suggest me some valid and useful solution.
