Finally had time to try and jb my new atv2 today, with greenpois0n. borrowed a micro cable, downloaded greenpois0n, and off we go, or so I thought!!! After 3 hours I still can't get it into dfu mode. I've tried every method on the internet. Tried on a mac and a pc. ATV doesn't even show up in itunes on the mac on the pc there is a usb error device, and an unknown device. I don't know if it is a problem with the lead or the device. Any ideas please?
