OK, I have a rooted Galaxy Note1 SGH-i717...when I recived this phone back from a family member I lent it to, I turned the phone on..the a few seconds later it turns itself off .Then when it reboots it self, it does a cycle, on and off(power)while displaying the "Samsung" Logo , So I figured id do a "Factory data reset" on it..After I did the rest I turn it on and it continues to do the same thing. So I read some forums and decided to flash it back to stock ROM, maybe tht would help..BUT as I go into "Download Mode/Warning screen" It wont let me use the volume button to chose (Up-For Download, Down-To reboot) and now as soon as it powers up it goes straight to the "Warning/Download Mode" screen and I cant get it to let me choose "Up-For Download" Can ANYONE HELP??:-X
