Tonight my SS S2 4G was on 5% battery. So I plugged it into the charger and went off to cook dinner. When I came back the little android logo was on the screen. There is red writing saying 'ODIN MODE' 'Downloading ... Do not turn off target!!'
I thought it must be some kind of update, but nothing seems to be happening. It has been sitting there for ages. Is it okay for me to attempt a restart?
