I have a Galaxy Note LTE for AT&T i1717 It will not power on. When I hold the power button it makes the noise(beep sound) like it would normally but nothing on the display shows up. I tried to do a hard reset (both volume and power hold) but nothing happens. I did get a response when I held down the volume down and power. It shows the custom mod screen so I know the display works!! Driving me crazy... yes i've taken the battery out and tried to reset. plugged it in multple times. NOTHING! And no Root was done. Anyone out there who can help?!
