If iTunes will not recognize it, it may not actual be in DFU mode.
Not saying that you don't know what you are doing but perhaps this may help.
Good luck.
DFU mode
INSTRUCTIONS
Step 1. Turn off 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 it’s 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
Here are a few more ways, some are the same but keep plugging along.
Method 1)
* Attach the phone to the pc
* Turn the phone off
* Hold power and home together for *exactly* 10 seconds
* Release power but keep holding home until the pc beeps as a USB device is recognized.
* At no point will the display come on. Now your restore should work.
Having problems? Try adjusting the 10 seconds to be slightly less like 9 seconds, then 8, then 7. It’s a tricky timing but you will eventually get it.
Method 2)
* Hook up the phone powered on to the PC
* Now hold home / power until the phone turns off and keep holding for 10 seconds. If the phone ever turns on during this phase,start over and hold for less time.
* Now release power and continue holding home until the PC recognizes the phone.
* I don’t like this method as much because there are “rumors” that it may cause some 1604 errors in the restore. I am not convinced of that though.
Method 3)
* Attach the phone to the pc
* Turn the phone off
* Press and hold power. Keep holding power. As soon as you see display on the screen of any sort press and hold home.
* Hold power and home together for *exactly* 10 seconds
* Release power but keep holding home until the pc beeps as a USB device is recognized.
* At no point will the display come on. Now your restore should work.

Have MAC OSX 10.5.6 or aMAC Book slim? You have a problem entering DFU mode. Here is an easy fix from the dev-team blog:
1. You will need an account with ADC (Apple Developer Connection) this is free and takes a few minutes to sign up, you should read the terms and conditions carefully and you should only sign up if you are thinking of developing applications in the future - Apple Developer Connection - Mac Dev Center
2. Download the disk image
“IOUSBFamily Log release for Mac OS X 10.5.5 Build 9F33” (yes, that is a “5” in 10.5.5 - this is a developer debug package of the USB kernel extension).
3. Install IOUSBFamily-315.4.1.pkg from within the disk image
4. Reboot your system.
