DFU means Device Firmware Update. If a restore using Recovery Mode doesn't work you will want to use DFU Mode as a last resort. When placing your iPhone into DFU Mode it does not load the OS before attempting the restore

Watch the Video!
For your convenience this tutorial is available in video format also. Click the Watch It button to view the tutorial!









To put the iPhone into DFU mode so you can do an iTunes firmware restore follow these steps:

Step One
Open iTunes and connect the iPhone to your Mac.


Step Two
Press and hold the Home button and the Sleep/Wake button at the same time.


Step Three
After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode.


The iPhone screen will remain black like this:


NOTE***: It may take a few attempts to get your iPhone into DFU mode. Generally, I hold down both buttons then release the Home button just before I think the Apple logo would appear. If you are still holding both buttons down and you see the Apple logo you are holding them down for too long!

Before you unlock your iPhone or enter in dfu mode you need to use an online iPhone IMEI Checker tool to determinate the iphone carrier and lock status only by imei code.

I can't see the purpouse of putting iOS 7 to DFU mode at the moment. However the instructions are following, try this: http://www.ipadconverter-mac.com/how-to-put-ipod-touch-into-dfu-mode/ 1) Power the device down 2) Start holding Power button for 3 seconds 3) Hold Home button but don't let go of the Power button, 10 seconds 4) Keep holding Home and let go of Power. About 15 seconds just to be sure That's it. You should now be in DFU mode.

This isn't DFU mode. You should either fix the tutorial or delete it. You're doing more harm than help.
