Though the simple steps to re-enable DFU Mode in Mac OS X 10.5.6 had helped few readers to re-enable the DFU mode in Mac OS X 10.5.6 which earlier prevented Mac from recognizing iPhone in DFU mode, making it impossible to jailbreak and unlock it using PwnageTool or QuickPwn, it had also caused serious problems for some of our readers.
At that time we had immediately updated the post warning users to proceed with caution and later to avoid it based on feedback from readers.
Wilson Rothman from Gizmodo who had followed the steps outlined by Gizmodo in this post via the same source that we had referred Hackint0sh ran into problems after couple of weeks.
His Warning message:
"Be careful with that latest QuickTime update if you have run any "DFU fix" Automator scripts"
He also narrates his experience, how he resolved the problem and some tips for all those who might have used the hack or have faced the problem.
The 10.5.6 update for Mac OS X Leapord that Apple released in December prevented Mac from recognizing iPhone in DFU mode, making it impossible to jailbreak and/or unlock it using PwnageTool or QuickPwn.
Gizmodo like us had also published steps to Re-enable DFU Mode in Mac OS X 10.5.6 to Jailbreak and Unlock iPhone.
Wilson tried out this hack to re-enable DFU mode on his unibody MacBook Pro. He did not face any issue for couple of weeks, but disaster struck when he updated his MacBook Pro with the latest version of Quicktime.
He explains:
Here is how he fixed his issue:
He highlights:
The now-mysteriously-missing original Hackintosh article mentioned that there were some issues with the unibody MacBook and MacBook Pros, but it never said that you should undo it after you finish jailbreaking.
He points to some other solutions such as:
- if you already ran the DFU script and haven't installed that Quicktime update yet, is try the method I have since discovered outlined in this Apple Support thread.
- If you still have access to your keyboard and mouse, you can copy the backup files (it should be under Backup_IOUSBFamily_kext_10_5_6 on your desktop) to where the automator script was, Install_IOUSBFamily_kext_10_5_5 on your desktop. Then, just run the automator script again, and it will copy those "original" files to the right location, then change the permissions correctly and reboot your machine.
- If you already ran the Quicktime update and you're unable to access any input (USB or otherwise), you can SSH into your machine and run these commands one by one. If you had trouble with the automator script, you can open up the terminal and do this too, manually. Note, some of these lines are too long, so they wrap to 2 lines. Make sure you copy it in its entirety. Commands are separated by empty lines inbetween.
sudo rm -R /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBHub.kext
You'll have to enter your administrator password here
sudo rm -R /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBCompositeDriver.kext
sudo cp -R $HOME/Desktop/Backup_IOUSBFamily_kext_10_5_6/AppleUSBHub.kext /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/
sudo cp -R $HOME/Desktop/Backup_IOUSBFamily_kext_10_5_6/IOUSBCompositeDriver.kext /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/
sudo chown -R root:wheel /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBHub.kext
sudo chmod -R 755 /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBHub.kext
sudo chown -R root:wheel /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBCompositeDriver.kext
sudo chmod -R 755 /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBCompositeDriver.kext
sudo rm -r /System/Library/Extensions.mkextprivileges
sudo touch /System/Library/Extensions
sudo reboot
Your machine will reboot after prompting to update boot caches, and the files should be back to the standard 10.5.6 ones.
Some readers who had used the hack faced this issue even before updating to the latest QuickTime update, so we suggest we follow the solutions provided above. As always, please proceed with caution.
In case your Mac is not recognizing your iPhone in DFU mode, then you should use one of these to be on the safe side:
Use a USB hub in-between the DFU device and the Mac and insert/reinsert the iPhone’s USB cable.
Use a PwnageTool created .ipsw on Windows or
Use QuickPwn for Windows
As always, let us know if this helped in the comments.
Thanks Wilson for the tips and sharing your experience.

this happened to me also. i called apple and they eventually had me put in the install disc and do an archive and install on my system. good as new after that.
same here, and that was the moments when I was so happy to spend the money on a Time Machine, all I had to do was, Start from the Leopard Install DVD (comand C) and then restore from the latest back up before the DFU script rewright, and then it was goo as new with all the same as before, so take my advise, buy a Time Machine, u wont regretted, and if u have the money to bye an iPhone then u can afford a Time Machine, believe me, its a wonderful tool.
Peace

hehe, sorry about that "buy"
It happened to me as well on my mbp (not unibody). script to mod .kext files did not complete and upon restart I had no trackpad or keyboard and couldn't use external devices as well!! Due to this could not sign into my account to fix the problem. I simply took out the hdd and attached it to another mac n downloaded the 10.5.6 update and installed it on my hdd attached via usb. Just told installer the target drive was usb n when done reinstalled my hdd and everything was back to normal!
what if i ran the dfu fix scrpit but have not updated quicktime, how do undo that apple script ?
once I reboot do I need to uninstall the files and folders
I lost control of my keyboard and mouse on my MacBook as described. My solution was to connect via screen sharing from another Mac. All inputs were working normally with the remote connection. I was able to use my TM backups to restore the latest kernel extensions and resolve the problem. I then used an older 10.5.4 boot volume to complete jailbreaking my iPhone 3G.
