The phone won't turn on. I tried my sister's battery and a red light shows. It flashes in a sequence. 3 flashes then 2 flashes. What can I do to fix it? I'm pretty sure that the lcd display is cracked. I was looking at it and it looked odd. Would that maybe be a problem why it isn't working. I wouldn't think so, but I don't know. What do I do to fix my phone.
