Talk:DFU Mode

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

Contradiction... can or cannot exit DFU without restore??

Can exit no problem ~geohot

Method one and method two are the same. ~geohot

Thought so. Cleaned. -drg

Hi all, please can someone make a utility to take iPhone into DFU. Or do someone know howto take iPhone into DFU without using Sleep button? ~ makovice

Please read the original article, It is not possible --JakeAnthraX 10:01, 17 November 2010 (UTC)

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)
