So I'll restore this phone to repeat the process of jailbreak and unlock, but 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 4.1, you’ll have error 3194 on iTunes.

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 eligible 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 eliminated 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.
Now here's the STEPS to be you to restore the same OS in your iPhone 3G!
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: 74.208.10.249 gs.apple.com
5. Restart your iTunes.
6. 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).
7. Now, restore your iPhone with your firmware iOS 4.0 (in windows using Shift + Restore, in mac using Options + Restore)
8. 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…
Here are some screen cap while editing and restoring:

After those process, I use redsn0w_win_0.9.5b5-3, then the NO WIFI unlock for iOS 4.0 that can be search all over the net! |
