Mac OS X 10.5.6 update breaks DFU Mode for iPhone?

Although they did post links to the 10.5.5 USB kext workaround, not sure why Dev-Team didn't also post the USB hub workaround -- which worked fine here for me on a Dec/08 MBP.

Direct cable connection exhibited the issues noted in the original article, but going through a hub (in my case, powered hub in monitor) was a snap.

p.s.: Not interested in pwnage news? Don't read the article or troll the thread. There is plenty of other Apple news you may be qualified to whine about.

yes this is definately legit and screwed up. i didnt even think that when i updated i wouldnt be able to jailbreak any longer. now i have an iphone 3g stck in dfu. what to do????

Hello everyone,

This is really silly. But connect your iPhone to your MAC using a USB hub. I did it by connecting it to the USB out of my Apple monitor. And it just works.

Good Luck!

I upgraded to 10.5.6, and nearly bricked my iPhone when I tried the pusher tool from ripdev. It took quite an amount of coercion to bring it back from the dead.

Dev Team believe this behavior is due to a kernel bug not a specific countermeasure by Apple. Possible fixes are (try at your own risk!) -

1. Replace the following plugin kexts from within IOUSBFamily.kext with the ones from 10.5.5 and then rebuild kextcache (if you don’t understand this, then you shouldn’t attempt it!)

/System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBHub.kext

/System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBCompositeDriver.kext

2. Use a USB hub in-between the DFU device and the Mac and insert/reinsert the iPhone’s USB cable.

3. Use a PwnageTool created .ipsw on Windows! Oh the irony!

These undocumented changes to the OS are 'trojan' to me.

Years ago, when I still used Windows, Microsoft once rolled a DRM change into a security update - so in essence unrelated *and* undocumented. I hated that.

This cat and mouse might be cute to some, but surreptitious changes to the OS reminds me of business practices I thought I'd switched away from.

If you want the files and directions for replacing the proper kexts so it works on yoru computer without a hub and what not just let me know

Please stop panicking and spreading rubbish,

Yes it breaks DFU if you plug it straight into your usb port, but all you have to do it use a USB hub.

I just tested this, and on my iMac late 2007 aluminium i can STILL enter and restore via iTunes in DFU mode.

"Could this be Apple's way of combating owners who jailbreak their iPhones?"

Not if you're a PC
