How to put iphone in DFU mode ?

Hello,
how i can put my iphone4 in DFU mode ?

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.

HOW TO GET MY IPHONE 4S OUT OF BEING STUCK IN HEADPHONES MODE? I TRIED BLOWING IT, I TRIED SUCKING IT AND I TRIED THE QU TIP, ALSO FREEZING AND PLUGGING AND UNPLUGGING THE HEADPHONES. I ALSO RESTORED IT AND PUT IT IN DFU MODE AND STILL NOTHING.

How do i get my iphone 4s out of being stuck in headphones mode. When i dont even have headphones plugged in, it says headphones ringer. I've tried blowing and sucking in the jack, didnt work. I tried using a blowdrier in the jack, didn't work. I also tried putting it in the freezer while in a plastic bag, trying to clean it with a qu tip, and plugging and unplugging the headphones more than 100 times, still nothing and i also restored, reset, and put my iphone in DFU mode, and still nothing seems to work. DOES ANYONE KNOW ANY OTHER WAY I NEED HELP PLEASEEEEEEEE!!!!!!!!!!! ANYONE ANY OTHER WAYS TO FIX IT?!?!??!? That would be very helpful

I had the same problem. I squirted a drop of WD40 in the headphone hole and then used a plastic dental toothpick and twisted it around in the hole. It amazingly worked.
Good luck

My iPod touch 64 GB doesn't charge or show up on iTunes, because the charger overheated it. How can I fix this problem? I tried restoring too and putting it into DFU mode but it doesn't work.

Thanks.

- See:
iPod touch: Hardware troubleshooting
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Iphone will not respond after trying to put it into DFU mode while in recovery mode.

I tried to restore my iphone 4 and recieved error 21 in itunes, while in recovery mode I tried to put it into DFU mode and then it turned off and wont turn back on or be recognized by itunes or pc. I tried doing a hard reset and no luck. HELP PLEASE!!!!!

That does happen. It depends on how hard the server is being hit, as well as the connection speed of your system. If you are on a windows system, you will want to disable any antivirus or firewall software during the download.

Activation server is not available on iphone 3GS i put it in DFU mode but still can not activate i went to apple store but they did not help?

There are four possible causes of the activation error:
The activation server is unavailable. Rare, but it happens. Usually fixed within minutes.
Your antivirus or firewall (or your router's firewall) is blocking access to the domain gs.apple.com on ports 80 and 443.
Your phone is jailbroken.
Your phone isn't jailbroken, but the computer you are connected to during the restore or update was used to hack or jailbreak some other iOS device, and its network database was corrupted in the process.
Perhaps this will provide you some clues as to how to proceed. If your iPhone has not been jailbroken, Apple has some troubleshooting suggestions here:

If your iPhone has been jailbroken, you're on your own. We can provide no assistance for jailbroken devices in these forums.

Hey jestinsinclairr,
Thanks for using Apple Support Communities.
After reviewing your post, it sounds like you had one issue and then got a second trying to resolve the first. A frustrating situation for sure. The first article linked has what to do if it is not powering on unless plugged in. The second article addresses the error you are receiving when trying to restore.

How do I keep the iPod Touch from people resetting it/putting it in DFU mode?

I have iPod Touch 5th Gen. iOS 6.1.3 again.I'm having surgery this week.My question is How do I keep the iPod safe from people doing stuff like putting it in DFU mode,resetting my stuff,etc. because I don't want people to get on my stuff while I'm having 1 hour/30 minutes of surgery?
Also,the surgery is just 1 hour/30 minutes.

Besides locking in a safe or giving it to a trusted person, all you can do is use a complex screen-lock passcode to protect your personal information. Someone still can erase the iPod by placing in recovery mode and restoring via iTunes but they will have to enter your ID and password to use the erased iPod

Connect iPhone to Wall Charger and Reset, hold both home and power buttons until the iPhone begins to start, this can take about 20 seconds of holding both buttons. If nothing, this means your iPhone has a hardware fault, most likely and hopefully battery.

My iPod won't turn on after putting it into DFU mode

I've tried the recovery mode after my iPod disabled for 4 times, unfortunately the recovery mode didn't work so I tried the DFU mode.
After putting it to DFU mode the screen suddenly turned white then turned back to black immediately.
I tried plugging it on my computer but it won't turn back on again.
Please help me.
