[iPhone] Issues with iPhone DFU mode in MacOS 10.5.6

Leave a reply

According to forum reports the iPhone DFU mode, which is required to install custom firmware with PwnageTool, does not get detected properly after updating Mac OS X to 10.5.6.

That means you cannot Jailbreak or Unlock the iPhone currently. The iPhone Dev Team has investigated in to this issue and comes to the conclusion that this is not a countermeasure by Apple, but a bug in the new kernel.

The Phone Dev Team names possible fixes for 10.5.6. As always: you do this 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!

If you did not update yet to 10.5.6 better don’t do it and wait for a fix or for 10.5.7 to be released.

[iPhone] Workarounds for Issues with PwnageTool/QuickPwn for Firmware 2.1

Leave a reply

We read all over the net and found some solutions to the most common issues that occurred. If you are kinda conservative user, we’d recommend not to update to firmware 2.1 and wait until a PwnageTool and QuickPwn update has been released. Since the iPhone Dev Team is reacting very fast, this should take only some days.

Known Workarounds:

Error 1600 and Error 6: restore with stock firmware 2.1, then QuickPwn (you may then put into restore mode and install custom IPSW, but it’s not necessary- credits to “HomeGrown”).

Error 1600: when Pwnage asks, if already pwned your device, answer NO, no matter if you pwned if before or not (credits to “Maurofoto”)

Error 1600: let iTunes download firmware 2.1 again (you may delete it from the local folder if you already downloaded it via iTunes. Folder on a Mac: ~/Library/iTunes/iPhone Software Update/), then exit iTunes, prep a custom IPSW using Pwnage, delete the iTunes downloaded firmware from the above mentioned folder again and copy your custom IPSW to that folder, but name it exactly as the original firmware was named (credits to “Markat”)
