I'm now *also* the first person to get the iPod nano w/ touch in DFU mode! Just like the one found on the iPhone/iPod touch/iPad, You need to hold the buttons in a certain combination 'which I do not remember exactly, I was trying to replicate the Diagnosis screen I *also* found' then the screen on the nano stayed blank. The computer (Windows XP) made the little 'ding' for a USB device, with "Apple DFU Mode" or whatev popping up. iTunes made a pop-up and said the recovery software needed to be downloaded... not firmware?? Well it did that, then the nano froze on the dark yellow-ish tint screen after flashing white 'just like on iOS devices', then the usual old iPod "do not disconnect" screen appeared. iTunes then told me I needed to restore the firmware, which is downloading (102.1 MB) as I type this.
