This video will show you how to Fix iTunes Error 3194 on a Mac – This device isn’t eligible for the requested build.
Earlier I created a video on how to Fix iTunes Error 3194 while using Windows. This video will show you how to fix the same error on a Mac.
You will need to open up Terminal in Finder and type the following command.
sudo nano /private/etc/hosts
Press Return and Enter your password.
Once you have typed your admin password you will see all the entry’s in the hosts file.
Now Apple says, look for an entry containing “gs.apple.com”.
The next step I delete any entry back to the local file which essentially sets the hosts file back to defaults.
However Apple says, Add the # symbol and a space (“# “) to the beginning of the gs.apple.com entry.
You can save the file by pressing Control-O. Hit Enter when prompted for the filename and Control-X which will allow you to exit the editor.
Restart your Mac and you should be good to go.
This video will show you how to Fix iTunes Error 3194 in Windows.
I found this iTunes error 3194 increasingly frustrating. I was about to start trying to do a Ragebreak Jailbreak on my iPhone 4 and this iTunes Error 3194 kept on coming up over and over again.
The error is caused by routing issues from having incorrect information in the local hosts file on your Windows PC.
You can find the hosts file in the following locations.
NT, 2000, XP, 2003, Vista, 2008, 7, 2012 and 8 %SystemRoot%\system32\drivers\etc\hosts Windows Mobile, Windows Phone Registry key under HKEY_LOCAL_MACHINE\Comm\Tcpip\Hosts Apple Macintosh 9 and earlier Preferences or System folder
Mac OS X 10.0 – 10.1.5 (Added through NetInfo or niload)
Mac OS X 10.2 and newer /etc/hosts (a symbolic link to /private/etc/hosts)
So I have been having this issue on and off with the redsn0w USB Communication Error. And I have had a few people ask me about it.
In this video I will show you how to fix it.
Step 1.Restart your PC. Step 2. Check your Cables. Step 3.Try a different USB port on your PC. Step 4.Try DFU mode again. Step 5.Disable your virus scanner. Step 6.Close any open programs or web browsers on your PC. Step 7.Check your device manager and make sure the USB driver is installed correctly and doesn’t have a ! next to it. Step 8.Try an earlier version of Redsn0w. Step 9.Download and use the correct IPSW firmware version for your iPhone.
You can find a list of all the firmware for the iPhone here.
I hope that helps.
