I just downgraded my jailbroken iPhone 4 from iOS 4.3.5 back to iOS 4.3.3 after accidentally restoring it to the latest firmware. Then entire downgrading process went smoothly and in the end my iPhone restored successfully. However, my iPhone is not booting normally. The device always gets stuck in recovery mode. I think I already tried every trick to get it out of recovery mode but nothing happened. I tried to restore it 3 times but no luck. Thanks.

Step 1: Download Zlib1.dll from heare and put it in the same location where fixrecovery43.exe is located.
Step 2: Then connect your iPhone 4 into the computer via USB cable and power OFF your device.
Step 3: Then launch TinyUmbrella (Fix Recovery) as well as iTunes and then 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 4: That’s it! TinyUmbrella (Fix Recovery) will do the job to fix the error.
Once you have fixed your issue, then you can now jailbreak it on iOS 4.3.3 using JailbreakMe 3.0 or Redsn0w. If for some reason that you’ve encountered iTunes 3194, then you can refer on this guide on how to fix it.
