What exactly does happen when you try to boot it? There are a lot of different things that "won't start" could mean, so we'll need more information to know what state the phone is actually in.

Like @Hadron already pointed out, 'won't start' means a load of things.

Does it power on then get stuck at boot screen, reboots constantly or doesn't power up at all?
