Minutes ago, Apple released the new OSX 10.5.6 update. We have to put a Big Warning on this update, because it causes problems with DFU mode. So with the Update 10.5.6 you cannot Jailbreak or Unlock your iPhone / iPod Touch with PwnageTool or QuickPwn as on the newest MacBooks. Update your System only if you really need it!

iTunes Failing to recognize the iPhone in DFU Mode (and in add it says “iPod”)

I’ve also informed the DevTeam and if they will release a patch, we will inform you!

Update: This is what MuscleNerd replyed about a fix for this problem:

The simplest workaround I’ve heard of for the DFU issue is to copy one or two of the 10.5.5 frameworks files over the newer ones.

Update2: Today we had a new post from the DevTeam:

DFU Issues in OS X 10.5.6

Lots of users have been experiencing problems with the use of DFU mode after applying yesterday’s 10.5.6 system update.

We 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!
