Hello Jaxov, I have SHSH blobs but iTunes is preventing me to restore my iPhone 3GS to custom iOS 4.3.3 IPSW by throwing error 1604 to me. The firmware was jailbroken and created on my Mac using PwnageTool 4.3.3. So, what should I need to do to restore the custom firmware on my device? Will this process work if I use a new iTunes and computer? Thanks.

Step 1: Download iREB RC4 for Windows from here
Step 2: Connect your iPhone to your PC through USB cable.
Step 3: Launch iREB and select your iPhone from the list of iOS devices.
Step 4: Then put your iPhone in DFU mode:
- Press the Home and Power button at the same time for exactly 10 seconds.
- Then release the Power button after 10 seconds but continue holding the Home button until iREB detects your iPhone in DFU mode.
Step 5: Now, iREB will start patching the iBoot of your iOS device using Limera1n exploit.
Step 6: Once done, you will see the confirmation message saying that Your device is now in Pwned DFU state.
That’s it! Just simply launch iTunes and restore the custom firmware on your device by the ALT (or Shift for windows users) button while clicking the Restore button.
