I have an iPod Touch second generation, 2.2.1. When I try to put it into DFU mode, it just doesn't work at all, I follow the DFU instructions that are on Quick Freedom, but nothing happens at all. I've tried to put it into DFU so many times and it just doesn't work. Can you put it into DFU using 2.2.1? I would be really grateful if you could help me.
