Hi, I’m new in the jailbreak scene and I totally had no idea that updating my iPhone’s firmware will remove its jailbreak. And when I tried to downgrade it using the saved SHSH Blobs I get an error saying that my device is stuck in recovery mode and then I get the 1015 error. This is very frustrating and I can’t fix this error, I have tried almost everything. Can anyone help?

Step 2: Download Zlib1.dll from here and put it in the same location where fixrecovery43.exe is located.
Step 3: Then connect your iPhone 4 into the computer via USB cable and power OFF your device.
Step 4: Start iTunes as well as the downloaded TinyUmbrella (Fix Recovery) and put your iPhone into DFU mode.
- Press and hold the Power and Home button for 10 seconds.
- Then release Power button after 10 seconds but continue holding the Home button for another 10 seconds.
Step 5: That’s it! TinyUmbrella (Fix Recovery) will start fixing the error on your iPhone 4.
After you have successfully fixed and restored iOS 4.3.3 firmware on your device, you can follow this guide on how to downgrade your device back to iOS 4.3.3 using TinyUmbrella. Once in iOS 4.3.3, you can now jailbreak iPhone 4 using JailbreakMe 3.0 or Redsn0w 0.9.6rc16.
