I was downloading a racing game on my Evo 4G. After the download was completed and the app was installed it asked me if I would like to get additional update and I said yes. I checked later that the app itself an the update are fine and not the cause of a problem since they are legit. The problem occurred i am guessing because when it was downloading that update, it had a sign "do not turn off until completed". Because I am a genius I did turn off the phone before the update was downloaded/installed. NOW the problem is when I turn on the phone it goes to my normal screen that asks me to drag down for unlock, as soon as I unlock the screen goes black. Its not dead, its just black. If I hold down the "home" button on the bottom left it will show me the recent apps that are ran but I cant turn anything else on. The screen is completely black and restarting the phone is not doing anything. Please help!!!!
