Try to run automator script or use powered usb hub to pass the dfu issue on a 10.5.6 mac...

If that method is not working, try this one.
1. Turn the iPhone or iPod OFF.
2. Plug in the USB cable into the computer, but not into the phone.
3. Hold HOME and POWER buttons
4. As soon as you are holding the HOME and POWER buttons, plug in the USB connector.
iPhone will now enter DFU mode and iTunes should recognize it.

Thank you so much for the suggestions. I actually got it not long after my post and am now in the process of unlocking/jailbreaking. Slowly but still I'm trying.

do you have to keep hold of home button (not the power) after you have connedcted to usb?

I would have thought it would be in the instruction manual.

Thanks so much for the help!! Wasn't looking forward to not being able to use my phone until dragging it into an apple store. Also didn't realize how strong my addiction to it was. Hmmmmm....

How to put your iPhone in DFU mode:
- Connect your iPhone to your computer.
- Turn your iPhone off.
- Hold power and home together for 10 seconds (exactly).
- Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
- A few seconds later iTunes should detect your iPhone.
- If you are successful at putting your iPhone into DFU mode, the screen should be black. If the Restore Logo is present on the screen, you are in Recovery Mode, not DFU.
DFU Mode is a special mode where the device can still interface with iTunes, yet it does not load the iBoot. The screen will appear totally black in DFU mode, so you canít guess whether the device is in DFU or powered down from simply looking at the screen. Because iBoot and the OS are not loaded this exploit allows you to downgrade your iPhone firmware or upgrade with a custom firmware created by Pwnage tool.
To exit from DFU mode and boot your iPhone normally, simply hold down the power and home buttons for ten seconds or until you see the Apple Logo and then release both buttons."When I die, I want to go peacefully in my sleep like my grandfather did...not kicking and screaming like the passengers in his car." -- Unknown
- Connect your iPhone to your computer.

turn off your phone hold the power and home button for exactly ten seconds and than release the power button and just hold the home button for ten more seconds and you will be in DFU..

It's the ten second method...and if you are on windows it will show up on iTunes and it'll say device driver software installing and then you know your in DFU mode

Hello, I have a crashed iPhone stuck in re-boot cycle. It has never been backed up. I have over 1,000 photos on it that I do not want to lose. I do not know how to put it into DFU mode, and I do not think that will help me, since that will only lead to me to "restoring" my iPhone in iTunes. This will erase my data.
Any help would be much appreciated! I am willing to pay someone to retrieve my photos! $$$
DataRescue types are saying they will charge me $1,000 & I cannot afford that...

The data recovery shop may be pirates, but they are also
your best shot at this point.
Are your photos worth more than $1000 or less than $1000?
It's a horrible equation, but the economics of reality aren't in your favor.
there's a procedure described in this post that's probably something along the lines of what a data chop shop might do
If you know what you're doing, it should help recover at least some of your photos. You'd almost certainly lose everything else. It involves restoring your iPhone to a clean OS image, and therefore is both risky and irreversable.
Will it work? If you know what you're doing, and are fairly handy with Unix and low-level filesystem monkeywork. You probably won't be able to recover all the photos- and some may be corrupt. If you're lucky, you may get most of them out. If you're not really familiar with Unix, or with iPhone hackery you're just as likely to end up with a clean iPhone and NO recovered pictures.
(I hesitate to recommend this route for the above reasons)
Also, what model is it? That could make a difference (in what options are available).

Thank you! I appreciate your efforts very much!
No, I am not good with Unix, iPhone hackery, etc. - so like you said - it's probably not an option for me.
As far as money, I am willing to pay up to $250 - but not $1,000 like they are saying it will cost me. I just don't have that kind of dough.
If you know of anyone who would like to try it, please let me know.
I am in the LA area and I will pay once I see my photos or we can make some other type of arrangement about the payment. I am very trustworthy.
