I forgot the PIN number of the lock screen.
I'm unable to do anything to get into my device as both data connection and Wi-Fi are off and USB debugging is disabled. Is there any way to enable them?
Otherwise suggest a way to root the device in this state and delete PIN and also to un-root it after the problem is solved.
I don't want to factory reset as I have important data on my phone's internal memory.
My device is un-rooted and runs on Android 4.4.4.
