iTunes Unknown Error 3194

The iTunes unknown error 3194 can appear for those who have an iPhone, iTouch or iPad. The downside of this error code is that there are a variety of reasons why it may appear, but the upside is that it is relatively easy to fix. In most cases, unknown error 3194 appears when firmware is being restored on an Apple device.

Anytime you try to restore a stock or custom firmware on an Apple device, iTunes sends a request to the Apple servers to verify the IPSW files associated with the Apple device and to sign the files with the Exclusive Chip ID (ECID) of the device being worked on. This is called the SHSH Blob. When new firmware is released by Apple, it can cause the Apple servers to stop signing the older versions, which results in the unknown error 3194 message.

As a workaround for this error, Cydia has created an SHSH blob caching server. If you run into the unknown error, you can correct it by pointing your iTunes towards Cydia’s servers instead of to Apple servers and save your SHSH blobs for your firmware there. To add Cydia’s SHSH caching servers, do the following:

• Download TinyUmbrella
• Install and launch TinyUmbrella
• Click on the Advanced tab
• Check the box beside “Set Hosts to Cydia on Exit”
• Click on Apply
• Reboot your device or computer

Once you have followed these steps, try to restoring your firmware. The unknown error code 3194 should no longer appear.

iTunes Won’t Start

It seems that many people who have upgraded to Windows 7 have reported issues with installing iTunes after the upgrade. While the issue can be annoying, luckily with a few small steps this problem seems to go away, at least for most users.

If you find that you are unable to launch iTunes you first want to make sure that after you install Windows 7 you have the correct installer for iTunes. For example if you are on 64bit Windows 7 then you will need the 64bit iTunes installer. You can download the proper installer at http://support.apple.com/kb/DL925. Downloading the proper iTunes installer may be the answer to your problem.

Starting iTunes in compatibility mode may also make a difference. To get to compatibility mode take the following steps:

• Right click on the iTunes icon.
• Click on Properties.
• Go to the Compatibility Tab.
• Click Run this program in Compatibility Mode.
• Select your operating system from the dropdown field.

If this is not the answer to the problem you may be prompted to turn off compatibility mode. Follow the prompts to do so and if possible force quit iTunes by hitting CTRL + ALT + DEL at the same time.

• Click on Start Task Manager.
• Go to Applications.
• Go to the iTunes Application.
• Right Click.
• Select Go To Process and then End Process.

Once you have force quit the compatibility mode, restart your PC and see if you can now open up iTunes. Sometimes just simply restarting your PC may be the answer to the problem.
If these options don’t work you will want to try to reinstall the Apple QuickTime which is required for iTunes. You will want to have the version of QuickTime 7.6.4 or later. It is possible that QuickTime got corrupted somehow. You can download QuickTime by going to the following site: http://www.apple.com/quicktime/download/. Once you download the program restart your computer and attempt to open iTunes.

It is very likely that one of the above solutions will be the answer to your problem, if not you can always contact the support offered with Windows 7 or from the iTunes site to assist with any further troubleshooting.
