Hi guys, I am trying to restore my iPhone 4 on iOS 4.3.3 using an IPSW created with iFaith tool. I have managed to save my blobs as well as create a signed IPSW of iOS 4.3.3. But when I try to restore the created iOS 4.3.3 firmware iTunes returns error 1601 and right now I am stuck in DFU mode. How can I fix this?

Step 1: First, you will need to download iREB RC4 and save it on your desktop.
Step 2: Connect your iPhone 4 into your PC via USB cable and launch the downloaded iREB-r4.exe.
Step 3: Then put your iOS device in DFU mode:
- Press Power and Home button at the same time for 10 seconds
- Release the Power after 10 seconds but continue holding the Home button
Step 4: iREB will soon start injecting the Limera1n exploit in the iBoot.
Step 5: Once completed, iREB will inform you that your iPhone is in Pwned DFU mode.
Step 6: Then wait for at least 10 seconds or so and launch iTunes.
Step 7: Once iTunes is opened, select your device at the left side panel. Make sure that you are pressing SHIFT while clicking on the Restore button, browse for the custom iOS 4.3.3 IPSW file and hit OK to commence the restoration process. If you have encountered error 16xx again, immediately disconnect your iPhone and perform the entire process again.
That’s it. You can now restore the custom iOS 4.3.3 on your device without getting any 16xx error.
