Iphone 5 stuck at apple logo, won’t enter DFU mode-help!

Hi, I attempted to jailbreak my iphone 5 with Evasi0n for ios 7 and didn’t realize ahead of time that the phone has to be ACTIVATED (it is a phone that an employee was using, but he switched accounts to another phone, so this one is currently not assigned a phone number). Now phone is stuck at apple logo and won’t respond to the DFU protocol, so there’s no way I can restore it. It does not show up in iTunes. Is there another way to reboot iphone or get it into recovery or DFU mode? I restored it through itunes before I attempted jailbreak because I thought it might have previously been updated over the air.
