  • UPDATED -- 10.5.6 Breaks DFU Mode?

    Update #2:
    Three official options from dev team

    1. Replace the following plugin kexts from within IOUSBFamily.kext with the ones from 10.5.5 and then rebuild kextcache.
    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.

    Cash Update: So I've been playing with this for a few hours now. 10.5.6 will not let you use DFU mode to restore custom firmware to a phone that IS NOT already pwnd. Replacing MobileDevice.framework with the previous version does not seem to matter either -- have not tried replacing the framework and downgrading iTunes or replacing other frameworks/haven't ahd time to dig in to the drivers and replace yet. A USB hub will work just fine with no issues at all to pwn on 10.5.6 with the latest iTunes. Had zero issues with my powered USB hub. Tired now and not interested in restoring anymore tonight so some updates from our members. One report says that QuickPwn works fine. If your iPhone is ALREADY pwnd and you need to restore with a custom firmware it has been reported to work. Windows users report no issues at all (of course) this is just a mac thing with the 10.5.6 update.

    According to some iPhone news sites, the latest Mac OS X release (10.5.6) disables the use of DFU mode. This can be bypassed by plugging your iPhone into a USB hub. The Dev Team has been notified on this and a fix will probably be here soon. For now, do not update to 10.5.6 if you want to jailbreak your device unless you absolutely have to...or have a spare USB hub.

    Basically it scattered reports are claiming that everything will work properly if you are connected to a USB hub instead of directly to the computer. The idea behind this is that the drivers for the USB hub will still allow you to connect in DFU and do your thing where the updated drivers in 10.5.6 when you connect directly to the computer would be fubared. What also would probably work is if you took the 10.5.5 [script]drivers[/script] framework and stuck it on 10.5.6.

    Here at MMi we will confirm things sometime tonight. If you have tested this out yourself post up!

    Oh and thanks to strchris for making his first post on our forums earlier today to warn the rest of us jailbreakers of the potential problem.

      My guess is, that Apple f****d up..... AGAIN

      Because since the update, I can't share my USB HDD via my network. It worked before the update but now i can't reach my HDD via Network.

      Some body else realized this?

      It seems to me, that Apple is closing on Microsoft quite quickly, at least in making mistakes.... I'm quite disappointed that Apple is following the same politics as MS, every Accessoire of the iPhone has to be baught, at least the 2G had a docking station, now another 29€ for that....

      iTunes actually puts your phone in DFU, but you have to be fast to catch it. Right as you select restore and it begins it says preparing your phone for restore, for just a split second you will see the phone flash white. Right as it flashes white, grab the phone off the dock. You'll be stuck in DFU and can then stick it back on the dock and continue.

      For just in-case...attached is a zipped copy of the 10.5.5 kexts that was mentioned.

      Myself still juggling whether to upgrade or wait, but some says the graphics performance improvement is awesome...

      Is it safe to go ahead with 10.5.6 if my phone has been jailbroken once but is not now for some time?

      DFU works for phones that are already pwned or quickpwned for some reason. This only applies to phones in a a factory OTB state.

      So Apple is now giving their lyoal customers incentive to run Windows systems? Clever!

      Strange how some people have a problem with this. I updated my OS from 10.5.5 to 10.5.6 using the combo updater. I've got the latest iTunes & Pwnagetool.
      I successfully went into DFU mode, using Pwnagetool, and used iTunes to do the custom restore. I did this on a 1st gen & 3G iPhone.
      Maybe the difference here is the COMBO update to 10.5.6. As a rule, I always do the combo update, as there always seems to be problems with incremental updates, especially done via Software Updater. Maybe those with DFU problems just needs to download the COMBO 10.5.6 updater, apply that and try DFU again.

      I tried to do all on this post, but I always got the (21) error on Itunes.
      But, WHY THE PROBLEM is in the CUSTOM FW 2.2, is because When I put the Original FW 2.1 or 2.2 in my Iphone 1st G. Itunes works great.
      When I try to use the Custom FW 2.2 I get different error.

      Hope that Someone find the error on this problem with MAC OS 10.5.6 or Custom 2.2 FW or Itunes 8 ... Anyway, the error is driving us crazy.

      I have an iMac Aluminum 24" with 10.5.6 and the latest iTunes. I followed the iClarified instructions and it worked no problem. Word of caution read the posts below the instructions becuase some where having issues and impatience. Mine worked just fine.

      I have iPhone3G with Pwnage 2.2 Jailbroken. But the Modem Firmware version was not 2.28.0 as required by YellowSnow. So I restored the iPhone3G using iTunes which downloaded the fresh copy of iPhone3G 2.2 (5G77). Phone restored and everything works. Then I tried to put phone into DFU mode and confirmed that a USB hub is needed. (Thanks for the tip.) Once in DFU mode, I option clicked the restore and navigated iTunes to the exact same restore image that had previously been used successfully to Jailbreak iPhone3G-2.2 (iPhone1,2_2.2_5G77_Custom_Restore.ipsw) and this time, iTunes choked with an error message and fortunately, after rebooting the iPhone3G, at least the un-Jailbroken version of Apple iPhone3G 2.2 works.

      Just a datapoint for you developers. 10.5.6 breaks more than USB DFU mode.

      What happens when you try to put the phone in DFU mode with Pwnagetool? Dose it say it failed and what color is the screen...if it is black then you will be able to install the custom ipsw you built. It has worked for me 4 out of 5 times.
