My 400k was rooted so I wanted to load the new software on using flash tool. So last night for 4 hours I tried and it won't. But my problem now is that I cannot get rid of this screen below. I have tried:
-battery pull - doesn't work and just comes back to screen
-any combination of buttons e.g. long press power button plus volume disc or long press power button only. None of them work.
-Drain the battery completely. Doesn't work back to that screen.
What can i do?
