If you don't see the message, repeat the steps above.

I am trying to work on this 3g for a friend of mine and its permenently stuck in dfu mode. Ok first off I have read tons on this subject and can say I have tried everything. While I know this mode is to restore from within iTunes, I have also tried using winpwn, quickpwn, and about 25 othger programs I can list if you like to upgrade, restore, downgrade and make custom ipsws to use in itunes. I tried reinstalling itunes to 7.5, 7.7, and updating again on 3 different machines with 3 different operating systems. Nothing works and the only errors I get are these: =error 1 for when I select the wrong ipsw not supported by the incorrect device (ie 2g or 3gs for my 3g, etc). =error 1600 and error 6.

Apple Device Dfu Mode

It always error 6's any ipsw that would otherwise normally work in or out of dfu mode. Now one thing I never see mentioned is the fact that after you put the iphone in dfu itunes always takes it out to do its fuctions eventually in the restore.

Its on dfu from the time its on, reset or otherwise put manually in that function. Itunes will bring it into iboot and restore modes on a restore but it always fails with an error (6). I checked the logs recently and noticed the same error inside there as well.

Ok on my xp machine i installed libusb again and ran irecovery. I coonnected and performed some norla commands and reset things where they should be but the iphone went oiff by itself. Did it all again and i exited and the iphone went off, not reset.

Its as if no mattewr what I do it remains the same dfu mode crap. Itunes always ends in an error 6 no matter the mode it begins in before updating or downgrading. If I could just install it manually maybe someone can tell me how to do so and have it function right maybe even using irecovery.

At l;east this program i can see the iphone in a little detail while its connected. But alas, after reboot command its as if i never typed squat.

Totally still same situation. Icq download for mac.
