Tip & How-To about Apple iPhone Smartphone

How to put you iPhone to DFU mode and restore 3.1.2 software version

CORRECTION:
I recently learned that RECOVERY MODE and DFU MODE are totally different. For that reason, I actually wanted to edit the title of this tip, but unfortunately, I can't, so I'm gonna write it here instead.
This instruction will guide you in putting your iPhone / iPod touch to RECOVERY MODE, NOT DFU mode because apparently, you'll know that your device is in DFU mode, only if your computer recognized that there is a USB device connected to it but you don't see anything in the screen of your device.PLEASE, TAKE NOTE OF THE CORRECTION. For instructions on how to put your device to DFU mode, CLICK HERE. For more detailed comparison, read from BigBoss' site.Procedure:

  1. While ON, plug your iDevice to your computer, it doesn't matter whether iTunes (on your computer) recognizes your device or not, just plug it in
  2. Turn it OFF
  3. Hold the POWER button (only button on the top-right corner of your iDevice)
  4. After just a second (literally, 1 second), press and hold the HOME button (only button on the face of your iDevice) and keep holding both buttons for about 10 seconds.
  5. Release ONLY the POWER button and keep holding the HOME button for another 15 to 30 seconds longer, or until you see this image:
This means your device is already in RECOVERY MODE and iTunes will recognize. This also means that you can restore your iPhone and make it operational again. But be warned though that restoring will wipe out all data in your iDevice, as if it's fresh from the box.
But, if your iDevice is DISABLED, you must put it to DFU mode first before you can restore it. For instructions on how to do that, CLICK HERE.

will not turn on


little more info. which phone, what was the last thing you did before it shut off? what are you doing to try and turn it on?

if you actually turned if off fully by holding down on the power button until you got the "SLIDE TO POWER OFF" option you actually have to hold the power down few seconds before the phone will reboot. this option is different than when you press the power button quickly to put it to sleep.

if all else fails you might need to restore your phone using the dfu mode. this is pretty good description on how to put it in dfu mode..http://www.iclarified.com/entry/?enid=1034

basically you connect your phone to iTunes. while its connected you want to hold down the home and power button at the same time and hold it for about 10 seconds. you should get a pop up message from your itunes saying it has found a device in recovery mode... just follow the steps to restore your phone to factory setting

How do I prevent Tenorshare iphone data recovery from crashing every time I try to connect my iPhone?


Hello, firend. iPhone Data Recovery for iPhone 4S is leww likely to crash and DFU mode is not needed. And the bug-fixed version is better than the previous. If it crashes really badly, you can apply for an exchange from Tenorshare.

what is dfu mode and how do you do it


You enter dfu mode so iTunes can detect an iPhone in recovery mode and then prompt you to restore. You will lose all your files when you do this but if you have a backup in iTunes then you're good to go. To enter dfu mode, just press both power and home buttons simultaneously for exactly 10 seconds. After 10 seconds, release the power but keep holding home then wait until iTunes detects your iphone and prompt you to restore.

iphone will not restore


Try restoring in DFU mode, which is different than recovery mode. I happened to stumble across it while trying to restore an iPhone 3G that a user unplugged in the middle of the 3.1 update. It kept showing an error of 1611 or 13 and wouldn't restore in recovery mode. I found this DFU mode option and the restore worked fine. The DFU mode keeps the iPhone OS from loading, so you don't run into as many compatibility problems. Go into DFU mode, then try restoring the phone and see if that works.

To enter DFU mode:
1. Connect your iPhone to your computer
2 . Turn iPhone off. You may have to hold the power and home buttons down together to force the phone off
3. Once the phone is off, hold the power and home buttons together for 10 seconds exactly
4. After 10 seconds, release the power button but keep holding home until the computer recognizes that a USB device was plugged in
5. iTunes should detect your iPhone correctly, and also allow you to restore to the factory default settings
