Hello, I just jailbroke a first generation Ipod touch with quickpwn 2.2.1 (version that supports the newest fw.) It worked good, but after I went to turn it on, it loaded the boot screen for a while. I tried rebooting it twice, and now i tried putting it into DFU mode. It wasn't recognised by Itunes and it won't turn on. I don'tknow what to do. Help?
