iPhone 3G Error 3194 when Restoring with iTunes…
Apple just updated its Firmware version into iOS 4.0.1 that has cosmetic signal bar changes that will make your signal more accurate, they said, and with the first and second bar higher than before so it can be seen clearly.
Sadly enough, for you guys who wanted to erase or restore your iPhone 3G into iOS 4 using iTunes 9.2 will be out of luck, since Apple is no longer signing the version 4.0 anymore. Instead if you insist on restoring your iPhone 3G into iOS 4.0 instead of 4.0.1, you’ll have error 3194 on iTunes saying that your Device is not eligible for this build, bla.. bla..
This is unfortunate, you can not upgrade your iPhone 3G officially, but.
You can still restore it unofficially.
Basically when iTunes showing “Verifying with Apple bla…”, that means iTunes is checking for signature from Apple’s signature server. And guess what, Apple no longer sign your iOS 4.0 firmware which makes your device is not elligible for restore, unless you update with iOS 4.0.1, this is one way for apple to force its customer to upgrade into the latest firmware, so all hacks will be elliminated if one is provided in Apple’s latest firmware version.
Now, we can bypass this signature checking when iTunes contacting Apple by changing the server from Apple’s Signature Server into Cydia’s clone of Apple Server.
It’s easy (for Windows):
1. Fired up your cmd.exe, and make sure you have administrator privileges.
2. Type this is: CD \WINDOWS\SYSTEM32\DRIVERS\ETC
3. Type this: edit hosts
4. Add this to the last line: 188.8.131.52 gs.apple.com
5. [UPDATE]: Save the file (People asked me to add this, it’s a common knowledge tho when you change a file you must save it)
6. Restart your iTunes.
7. Put your iPhone 3G in recovery mode, by turn off the device first and pull the plug from your PC. Then press Home Button and connect your iPhone into your PC, then wait until the Recovery Icon shows up (iTunes icon with cable above it).
8. Now, restore your iPhone with your firmware iOS 4.0 (in windows using Shift + Restore, in mac using Options + Restore)
9. Voila, it will be restored succesfully, it’s fully working on my iPhone 3G.
You should notice the number 4 step is the bypass server, by pointing Apple Authentication domain into Cydia’s Server IP Address, this is trivial in unix, and thankfully, we can do this in Windows.
On Mac, it’s the same, except for the cmd.exe and the cd thing should be into /etc/hosts…
Enjoy your Jailbreak Restore…
The use of Cydia server doesn’t need you to download any software, but if you still having error using Cydia server, you can download TinyUmbrella from thefirmwareumbrella.blogspot.com
You can then start its TSS server and replace the step number 4 with :
And still on the very same hosts file. Some people called it stupid, but this is simple way to bypass the iTunes from connecting to the real Apple Server, if you have better way to do this, just tell me…
