DFU sta per Device Firmware Update. Se il ripristino con la modalità Recovery non funziona è possibile usare la modalità DFU come ultima risorsa. Quando l'iPhone si trova in modalità DFU non avvia il Sistema Operativo prima di fare il ripristino.

Per mettere l'iPhone in modalità DFU e poter ripristinare il firmware da iTunes fai come descritto nei seguenti passi:
Primo Passo Apri iTunes e collega l'iPhone al tuo Mac.
Secondo Passo Tieni premuto contemporaneamente sia il tasto Home che il tasto Standby/riattiva.
Terzo Passo Dopo esattamente 10 secondi rilascia il tasto Standby/riattiva. Continua a tenere premuto il tasto Home fino a quando iTunes non apre una finestra con un messaggio che ti informa che ha trovato un iPhone in modalità Recovery.
Lo schermo dell'iPhone rimane spento, così:
NOTE***: Potrebbero essere necessari alcuni tentativi prima di riuscire a mettere l'iPhone in modalità DFU.Generalmente io tengo premuto entrambi i tasti e rilascio il tasto Standby/riattiva un'attimo prima che venga visualizzato il logo Apple. Se stai ancora tenendo premuto i due tasti quando vedi il logo Apple allora lo hai fatto per troppo tempo!

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.
