iphone stuck in dfu mode, screen black, apparently dead

guys, need please.

messing friend's jailbroken iphone, needed in dfu mode restore did wrong because phone stuck blank screen , nothing can make itunes recognize it.

it's unlocked iphone 4 running jb 5.0.0 ios.

can't boot no matter what.
doesn't show under usb devices connected.

left connected wall charger -i read somewhere while in dfu mode, phone isn't charged, said helped somehow- without success.

i'd prefer not have apple service because guess can boot , see has been jb.

thanks.
