about my own experiences of the 10.5.6 DFU fix, before I found this thread.

The only important thing with the Automator solution is to put the folder with the Script on the desktop - thats all.

One more: Once you got your iPhone pwnaged you could revert the "downgrade". You would just have to put the two bundles from the backup folder (the one that is beeing created during the script's run) into the folder that contains the Automator script (replacing the two from 10.5.5 that come with the script) and then run the Automator app again ;-)

Thanks for the info re. reverting. Handy even though I don't seem to need it with your fix

But the Rapidshare link to the IOUSBFamily.kext file is expired/overused. Can someone please re-post a link? Thanks, E

BTW, I'm using a 3g firewire ipod in disk mode as my "install disk" which is how I originally got leopard on my system. I'll update with my experience with this setup (although it should be the same).

what we have: macbook (1.5 y.o.), leo 10.5.6
what s the problem: after the fix, regular apple keyboard & logitech mouse + macbook's keyboard & touchpad not working, no way to install 10.5.6 combo update
what i try: boot in safe mode, boot in single mode, fixing permissions (leo boot dvd > disk utility) - no answer from usb ports
what we need: 1 flash drive (any capacity), 1 pc or mac (except not working mac), leopard install dvd, original file ( RapidShare: Easy Filehosting ), 10.5.6 combo update ( Apple - Downloads - Mac OS X Updates - Mac OS X 10.5.6 Combo Update )

1. copy file (IOUSBFamily.kext) to your flash drive (before downloading file, empty flash drive)
make a folder structure on flash drive like this:

System>Library>Extensions
put in Extensions folder file "IOUSBFamily.kext"

the way will look like this: FLASH_DRIVE_NAME/System/Library/Extensions/IOUSBFamily.kext

capitalization is very important!!

2. boot leo install dvd (hold "alt" button after power on), then go to "Utilities" > "Disk Utility"

click on your macintosh hard disk and go to "Restore" section
drag your flash drive and drop it in "Source" empty bar
drag you mac hard drive and drop in "Destination" empty bar

DO NOT MARK "Erase destination"!!!

Then click on "Restore"
wait
quit Disk Utility

3. go to "Utilities" > "Terminal" and type:
chown -R root:wheel "/Volumes/NAME_OF_YOUR_MACINTOSH_HD/System/Library/Extensions/IOUSBFamily.kext/"
chroot "/Volumes/NAME_OF_YOUR_MACINTOSH_HD/"
kextcache -k /System/Library/Extensions

capitalization is very important!!

quit Terminal

4. go back to Disk Utility
in section "First Aid" click on "Repair Disk Permissions"
wait
quit Disk Utility

5. restart your mac and hold "shift" button. mac os will boot in safe mode whit working usb ports

6. install 10.5.6 combo update

well done =)

Mac OS X 10.5.6 was released on December 15th, 2008. It disables recognition of a device (like the iPhone) in DFU mode. It is not known if this is intentionally disabled by Apple or just a bug. The iPhone Dev Team believes "this behavior is due to a kernel bug not a specific countermeasure by Apple."
All credit for the solution goes to the iPhone Dev Team - as usual, I have just developing this easy to use app!!!

One solution ist to replace two plugin kexts with the ones from Mac OS X 10.5.5 and then rebuild the kextcache. This innvolves some knowledge of the system and heavy use of the application Terminal.

This is where the Automator programm Fix_DFU_10_5_6 comes into action. I put it together to do the complete job with one mouse click. The user has to be logged into his Mac with administrator privileges (usually the account you used while setting up your Mac) and has to provide the admin's password.

The programm then:
1. checks if you are at Mac OS X 10.5.6 or better (if not will quit)
2. show a readme
3. quits all running apps (with save option)
4. backup the original files (AppleUSBHub.kext and IOUSBCompositeDriver.kext from 10.5.6) in a new folder on your Desktop
5. ask for your admin password
6. copy AppleUSBHub.kext and IOUSBCompositeDriver.kext from 10.5.5 into the desired location on your Mac
7. set owner:group and permissions
8. rebuild the kextcache
9. reboot your Mac

Right at the end the programm will tell you that the cache is beeing rebuild, just let it do its job.
Your Mac will automatically reboot when done - DFU is enabled then.




How-to (see pic below)

Download the package (zip-archive) at
Rapidshare
or
Mediafire

Unzip the archive (pic 1) and place the folder "Install_IOUSBFamily_kext_10_5_5" on your Desktop (important). Open the folder and start the Programm "Fix_DFU_10_5_6" (pic 2).

You will see the Readme box (click "OK") (pic 3), then you have to provide your admin password (pic 4). The programm then will do its job.
At the end the Finder will open another dialog box telling you that the cache is beeig rebuild (pic 5). Klick "OK" or just leave the box alone. After a couple seconds your Mac will reboot automatically - done, DFU is enabled again.

On the Desktop you will find a new folder called "Backup_IOUSBFamily_kext_10_5_6", it contains the two 10.5.6 files

Hope this helps,
v.
