iPhone 3194 error

[badboy]

Hi guys, hope someone can help.

I have a iphone 4 on firmware version 4.2.1 and i want to update it to 4.3.3 so i can jailbreak it using jailbreakme. I have downloaded the 4.3.3 firmware and when i press shift, select firmware file and click update or restore, i get the below error message:

iphone could not be restored. error code 3194

Look forward to your replies.

Thanks

not sure but isnt that the error u get when trying to downgrade the firmware? an apple guy once told me you cant go back with firmware unless you use greenpoison or something similar..

i could be wrong!

take it to an apple store i think they will need to restore it themselves.

still under warranty?

Error 3194 seems to be triggered when unsigned firmware is used, often during an iOS downgrade or even during some restores.

fix Error 3194
The fix is the same regardless of what operating system you are
using:
Quit iTunes
Locate your hosts file, in Mac OS X this is /etc/hosts and in
Windows this is c:\windows\system32\drivers\etc\hosts
Open the hosts file with Administrator privileges
Add the following lines to the very bottom of the hosts file:
74.208.105.171 gs.apple.com
Connect phone to the computer
Launch iTunes
Put the iPhone/iPad/iPod into DFU mode by turning the phone off
and then holding down the sleep and power button for 10
seconds, then release the power button but hold onto the home
button until iTunes tells you that the device is now in recover
mode
Use the iTunes Restore feature as usual with the iOS device
