First off all, before you all talking about googling, yes i did it, and a lot! :O I've restored my ipod 4 times and tried every single dfu mode possible. It sucefully enters in Dfu mode (black screen and a "have to" reset and restore) but my itunes doesn't responds to the ipod, don't says "your ipod is in the dfu mode" (something like that). I've tried everything. What could this be? Im on a 32gb ipod touch on a 2.01 firmware if it helps... Thank you all!
