Okay, so, we know that iTunes puts the iDevice into DFU mode when the device is upgrading/downgrading/restoring. How does iTunes do this? It certainly doesn't require us to press and hold the home/sleep buttons. How do we reverse iTunes' mechanism to put devices into DFU mode WITHOUT creating a DFU loop?

failsafe thing was made up by zibri, his point was you can always downgrade to 1.1.4, but it is really officially known as Device Firmware Upgrade by the people actually invented it :P

It is possible but your iDevice will go into a DFU Loop. --Whiteshinyapple 18:10, 19 November 2010 (GMT +8)
Thanks for your interactions. I'll suggest repair the button ;) (DFU Loop I tried, but without success - iTunes refused modified firmware) -- makovice
iTunes will error out and if your iphone is in a black screen then it is in dfu mode. -- Whiteshinyapple
Yeh I know, but it doesn't even start restore (iPhone didn't make anything), so did anyone try it with 4.1 iOS and iTunes 10.1?? -- Makovice
well the way i did it was used PwnageTool or redsn0w to enter pwn DFU Mode (tested this on 4.0 because i don't have SHSH for it) then without unzipping the .ipsw (this is important because it will not be recognised by itunes if unzipped) removed the build manifest then restore and it will give you error 10 and every reboot it will be in dfu mode however if you are wanting to save the data in your device it is impossible because the bootchain is flashed at the end of a restore --liamchat 16:00, 22 November 2010 (UTC)
ok, only one thing ... how can I change conent without unzipping? :) -- Makovice
i used http://www.stuffit.com/mac-home.html --liamchat 16:52, 22 November 2010 (UTC)
any zip program. Winzip winrar peazip anything just view the file on the program and delete the file like in explorer or finder... --Balloonhead66 17:36, 22 November 2010 (UTC)
Ill be creating a video on how to create a DFU Loop IPSW.My Youtube --sn0wra1n
on an intresting note it may be posible to make a dongle to boot the device ( like [1]) but when redns0w boot's tethered it inject's big file's and the ipod 4g has a void in it so the dongle will not be visible --liamchat 18:11, 25 November 2010 (UTC)

Okay, so, we know that iTunes puts the iDevice into DFU mode when the device is upgrading/downgrading/restoring. How does iTunes do this? It certainly doesn't require us to press and hold the home/sleep buttons. How do we reverse iTunes' mechanism to put devices into DFU mode WITHOUT creating a DFU loop? --The preceding unsigned comment was added by Rdqronos (talk) 04:26, July 1, 2011 PDT. Please consult this page for more info on how to sign pages, and how to fix this.

No one but Apple has the source code. I guess you could attach a debuger to the USB port (if there is one that does that) and monitor the data sent out of it. --Balloonhead66 15:09, 1 July 2011 (UTC)
