I was trying to boot my iPod. So naturally I put it into DFU mode and started sending the commands. I sent !iBSS211.dfu, and #pwn211ibss.txt. But when I sent !iBSS221pwn.dfu, It flashed, then turned black, and my Mac indicated it had disconnected. rslite detected no device. I went like, wtf. So I tried again. Three times the same result. By now I was very nearly starting to freak out. And I tried the fourth time. And it worked. I was very nearly expecting to have to restore. It's working now, but insight into the cause would be nice. Could it be because I haven't disconnected it in three days? Should I have tried disconnecting and re-connecting it the first time?
