[Help] iPhone 4 not turning on after entering DFU mode

[cheesyappleuser]

I was trying to jailbreak my iPhone 4 in 4.3.1 version few minutes ago, and I put phone in DFU mode, as redsn0w 0.96rc12 said, but, although computer recognized phone entered in DFU, redsn0w didn't, and now my phone is not turning on, and I didn't jailbreak it.

Can you help me, please?

I'm running Windows XP, and redsn0w crashed at 1st attempt while changing firmware files.

Thanks in advance
