The phone works but the guy at the store had to do a hard reset to get the screen back but it only works with it open and i have to put the speaker on to hear who I'm talking to the mic doesn't work. Now it cant get it to hard reset. I have not a clue what is wrong. I would just like to use the phone til i get it replaced. Any help?
sounds like you have hardware issues on your phone if you ask me.... try to reflash like jew said and if that doesnt work i would have to say that the phone is a goner.
