Phone suddenly restart one day and stuck in the Samsung screen (the one after showing Galaxy note 2) with the samsung logo flashing. Battery is fine and I can get into download mode (hold volume down, power and home button). I tried flashing it with Odin, but it always fails. Could not get to upload screen (volume up, power and home button). I got some photos that I have not backed up and would like to recover the files. Please help!
