Phone went crazy today. Crashed, then entered download mode (it was taking forever, I was in a meeting, so I reset it and thought I'd be able to enter this mode again), then stopped entering download mode and started yielding shitty error messages. So, starting it with power button and both volume keys pressed yields a screen that has a lot of error text. The volume keys cannot move, cannot select anything. The one button that does work is the home button, which when pressed just hides the text and shows the error icon in the background and when pressed again shows the error text. Did my main internal storage fail? Where do I proceed from here? Odin3 does not recognize a connected device when it is in this state.
