How To Put The iPhone Into DFU Mode

December 5th, 2007 · 242 Comments · Apple, FAQ, iPhone

iPhone DFU Mode

If you are getting error (1) or error (6) while downgrading the firmware, you need to put your iPhone in DFU mode before you can restore or downgrade the firmware.

Step 1. Turn off your iPhone.

Step 2. Hold down the power and home button.

Step 3. When you see the Apple logo, release the power button but continue holding the home button down.

Step 4. Open iTunes and wait for it to tell you that its in restore mode.

Alternative Method:

Step 1. Connect iphone to USB then listen to the sound when it connect and disconnect.

Step 2. Hold the home and power buttons until hear the disconnect sound then release power button.

Step 3. Wait until you hear another sound then release home button.

Alternate Method: Going Into DFU Mode Without Button Pushing: (on windows) Easier than timing the buttons just right!

1.) First download the required archive

2.) Extract the archive to the root of your hard drive, should be C:/DFU/

3.) Connect your iPhone and ignore iTunes

4.) Goto Start – run

5.) Next type in “c:/dfu/dfu iBSS.m68ap.RELEASE.dfu”

6.) Wait for iPhone to show a “white” screen

7.) Now you may proceed to downgrade!

**also these files are found in ibrickr’s directory except for the .dfu file**

        Hello mate i have tried all options of getting it into dfu mode and nothing seems to be happening i am trying to downgrade my 4.0.1 firmware to 4.0 but struggling to do so please help

        • Chris

          just in case you still havent thrown your iPhone out the window: you have to copy your actual iTunesMobileDevice.dll to the DFU folder and extract your ipsw and go to the Firmware folder, then DFU and copy the iBSS.***.dfu file to the DFU folder and run THAT file 😀

          • Dools

            Please ! I’m trying that, but it works not. I have iPhone 3G with iOS 4.0.1. I’ve put the last itunesmobiledevice.dll and IBSS file from official firmware 4.0.1, and dfu.exe in “C:\Program Files (x86)\Common Files\Apple\Apple Application Support” Because it was asking for ASL.dll. But it isn’t working.

          • Masaki

            Hey Chris I don’t understand what your saying can you like tell me the steps please

  • Mishonio

    I am in the same boat – HOME button doesn’t work on my iPod touch 1G (fw221). Haven’t tried the DFU tool on this site yet, but doesn’t seem like it works on any of the newer firmwares.

    Please advise if you find out something that works to put device in DFU mode relying on the HOME button


  • Mishonio

    is there a way to use the “no button” method on the 3.0 firmware? My home button is broken, so i can not get it into DFU for jailbreaking. I tried iliberty, ziphone and the other apps out there, but neither did get me to DFU. Please let me know if anyone finds a method for the 3.0 firmware that works. I am stuck here 🙂

  • jUAN cHIA

    Thank you so much…Mine complete worked!!!

  • Andre

    Question, guys. Do you have to put your iPhone/iPod in DFU Mode?

  • Dan

    HI guys,

    thanks for all the contributions.
    I wonder if anyone had the DFUE without buttons on iPhone got working on a 2G 2.2.1 ?

    My power button no longer works… So in a similar situation as the no home button users. I cannot get into the DFU Mode as one button is not functioning.

    Happy for any ideas on solving this.

    • ivan

      hey had same problem easy fix wait till it dies only way. once it dies connect ur usb to a windows computer then hold homebutton for 15 sec and connect it still holding it and it will put to DFU, hope this helped.

  • Josie

    Hi Guys,

    Im trying to Jailbreak my 3g 3.0 using Redsnow, when i get to step 3, the phone is not being read…it keeps counting down to 0 seconds and it will say error, reference youtube or google for help…can someone please help me?

  • daitan

    I have an 8gb iPhone 3G. Last night I was talking on Palringo with some buddies and one of them sent an insanely large image which hung at 99% and then when it finally loaded, everyone’s text messages started spamming me and about 5 seconds later it said “No Service” at the top left. A couple seconds after that it kicked me to the “Restore Needed” screen with the usb cable/itunes image. I tried downloading the 3.0 update and restoring but it said “The iPhone “iPhone” could not be restored. An unknown error occured (23).”

    I’m iPhone stupid so step-by-step instructions on how to fix this $400 paperweight would be greatly appreciated. 🙂

  • Stimburg

    None of these steps work, it just hangs on the apple logo screen. These phones cost to much to not work properly and apple support is just horrible.

  • Ananymous

    Hi all, I was so stupid that I tried to upgrade my jailbroken Iphone to 3.0.1 not regarding my broken power button. So I cant get into DFU mode either… If anyone know a program or a workaround to get into DFU mode preferrably on a Mac it would be greatly aprecciated!

  • makecashonline

  • lloyd

    hey, i got an iphone 2g that was unlocked, let a friend borrow the phone, he thought he was doing me a favour and upgradded it, now its locked to 3.0.1 firmware.
    my sleep or wake button dont work so cant get into dfu mode that way, i tried ziphone and it just says its not responding when it try’s to run it.
    i tried iliberty but had no success,
    i also tried the start and run method on windows, still no success.
    im stuck without a phone and really need some help or tips of what i might be doing wrong or other methods
    please help, you can email me on

    • Eivind

      I am also locked to 3.0.1 with iTunes symbol and usb cable on the screen with a broken power button. Have anyone found a solution?
      The start and run method doesnt work for me either.

    • Daniel

      Hi Lloyd,
      ask a friend to repair the button – that was the only way for me to get it back up and running…

      best luck!

  • andrea

    I have the same screen with the cord connecting to itunes on my ipod touch. I tried calling apple but they were no help, and I can’t restore it because it needs a passcode but I can’t enter the passcode unless it’s on! please, please, pretty please help

    • Joe-joe

      Hey, I got the same problem with you. All you do is go to DFU mode then restore your iphone. Then Jailbreak it. It should only take you atleast 30 mins to do all this. For jailbreaking use redsnow then to unlock to any carrier is ultrasno)w

  • Penny

    Hi guys. I have an iphone 3g that was jailbroken and unlocked. It was accidentally updated to 4.2 via itunes. Now it’s locked and not jailbroken. I’m trying to jailbreak via Redsn0w but I can’t get it in DFU mode. Have tried literally over a hundred times. Any help? I’m desperate.

  • Phil2

    This is idiotic, all these comments.. The dfu program DOES NOT WORK, I just tried it multiple times multiple ways, type the directory in run just opens the folder and that’s it.

    When I run the file with the dfu app, wich I guess is the point?! It gave me one .dll file after another that was missing so I copied every .dll file it needed, got it running again, then it started working, and the first thing it did was place my iPhone in “Recovery-mode” not in “DFU”.

    After that it said it was sending stuff, and then the app crashes.. After multiple tries it still crashes every single time.

    no use, I need an other method to get it in DFU mode without the power button

  • Loan

    ThankYou, ThankYou SO MUCH! When Last Night My IPad was being weird i turned it off and it wont turn back on the only thing on was the Apple Logo.

  • RepelsTechnology

    I’m having the same problem as Loan, I recently got an iPod touch (4 g) and its worked great, earlier today I was playing around on it and I turned it off because it was acting strange. I tried turning it back on but all that came up was the Apple logo. I tried restoring it about four hours ago and it just finished about 30 minutes ago and nothing has changed, all that its doing is showing a pig silver apple. I really don’t know what to do. Help?

  • iSmokilos

    My sleep button is broken. Is there any other way to enter DFU mode without using the sleep button?????

  • chris

    This worked for me (on a Mac)

    1. Hold both the top power and home buttons down until the Apple logo appears.

    2. Once the Apple logo has appeared release the top power button and continue holding down the home button.

    3. With the home button held down, open iTunes and wait for the iPhone to go into it’s restore enabled state.

    Hope this helps.
