[AC Question]

Earlier today I started installing the latest android update and left the phone to do its thing for a while. When I came back I found it with the android figure lying on its back with the words no command written underneath it, after about 20 seconds the words google come up in white and after about the same time again it goes back to no command. After some research I found that you can fix this by holding the power button and voulme up key, however I recently dropped the phone and the volume key was crushed, so now only the bottom half of the key works. Is there anything else I can do that does not involve the volume up key??
