DFU significa 'Device Firmware Update'. Se um restore usando o método recuperação não deu certo você vai querer usar o modo DFU como uma última tentativa. Quando colocar o iPhone em modo DFU ele não carrega o SO até que a recuperação tenha sido feita.
Vejao video! Para sua conveniência este tutorial está disponível de formato de vídeo também. Assista ao vídeo abaixo...
Para colocar o iPhone em modo DFU siga os seguintes passos:
Passo um Abra o iTunes e conecte o iPhone ao seu Mac.
Passo dois Pressione e segure o botão Home e o Sleep/Wake ao mesmo tempo.
Passo três Após exatamente 10 segundos solte o botão Sleep/Wake. E então continue segurando o botão home até que seu iTunes tenha mostrado uma mensagem que detectou um iPhone em modo de recuperação.
A tela do iPhone continuará preta como esta:
NOTA***: Talvez você leve algumas tentativas para conseguir deixar seu iPhone em modo DFU. Geralmente, eu seguro ambos os botões e então solto o botão home antes de pensar que o logo da Apple poderia aparecer. Se você continuar segurando ambos os botões você está segurando eles por tempo demais.

hey I just got an iPod touch 5th generation and it was my but he's ex-girlfriends when they broke up she gave it back to him but never told her iTunes password how do I get around that and restored to factory settings any idea?
Very narrow minded to think that the phone is stolen. I am a company admin and deal with all the time when ex employees put their personal icloud account on my corporate phones.
This is also not uncommon for people buying/selling used phones. If the seller does not go through the setup and deactiavte the account, the buyer will have issues.
how can u do it if screen has passcode and is cracked/unresponsive and have no idea what the itunes account info is cause person it was bought from is looney tunes?!
This solved my "ipod touch upgrade ios 2.2.1 to 4.2 error -1" problem I have had for more than a year.
Thank You.
Remember to backup your latest state of the IPOD.

For the record, my ipod touch is 5th gen, and my laptop 10.6 . And when I followed through with the instructions it worked until I got an error message of 4005, and basically my laptop's version of itunes was not up to date, although it said it was. Currently the latest version is 12.0.1. And my laptop was reading "This version of itunes (11.4) is the current version", which is incorrect and misleading. So I switched to my later model - and it works. Ensure that your stuff is up-to-date or it won;t work.
