Here is a list of i Tunes errors that could appear when you restore i Phone, i Pad and i Pod Touch using i Tunes. Occurs when you want to install a beta firmware with i Tunes for Windows (actively blocked by Apple; beta users are developers and therefore must have a Mac). Check the USB connection and try other direct ports or maybe the USB cable is an older one. This error can also happen when you try to restore an i Pod with hardware dfu. or You are trying to update to a beta firmware without UDID activation.If the problem still exists after you view this post, please find more details solutions in this post "Due to asr being patched, the SHA signature is automatically changed and after being resigned the kernel will refuse to use it. If necessary kernel patches are not applied, it will fail to load asr and error 9 would occur during restore. The problem is a bad dock connector on the i Phone. If you have tried almost everything, reset the logic board leave uncharged for 2-3 days or remove battery for an hour. Restart computer; change computer; reinstall system, if i Phone is always in restoring mode: XP users can jump from restoring mode with ibus; MAC users can use i Ndependence.
It can be resolved by updating to 10.5.7 (or later), or using a USB hub.
Occurs when trying to install an old firmware and Apple's server disallows the installation.
The only solution is to have SHSH backup and modify the hosts file to point to Saurik's Cydia server where they are backed up (or localhost if you have it yourself).
This error happens if you are logged out, try to download something from the i Tunes store and if you click on "Download" and enter an account, which doesn't have this article, this error will occur.
Check the USB connection and try other direct ports or maybe the USB cable is an older one. Reportedly happens during failed downgrade attempts, Some have seen success afterwards by doing the downgrade from DFU mode instead of the normal Recovery mode.
(usually on the i Phone with 1.0.2 firmware downgraded from 1.1.1) Restart computer; change computer; reinstall system, if i Phone is always in restoring mode: XP users can jump from restoring mode with ibus; MAC users can use i Ndependence.(usually on the i Phone with 1.1.1 firmware downgraded from 1.1.2) Baseband firmware on the IPSW is higher than the baseband firmware on the i Pad/i Phone.The Mac OS X kernel extension "IOUSBFamily" that was bundled with late 2008 / early 2009 Mac Books, has a bug where it fails to properly recognize an i Device in DFU Mode.Its come to my attention that a lot of people are having issues syncing i Pads, i Phones and i Pods to i Tunes.It would seem that even though the device is set up to sync with i Tunes correctly, sometimes it just feels like being a jerk and not syncing.I’m a big fan of Apple products, but it’s no secret that syncing with i Tunes can be a little buggy.
