I have downgraded my factory unlocked iPhone 4 after accidentally updating it to iOS 4.3.5 last week. Good news is that Cydia have saved the SHSH blobs of my device. Anyway, after jailbreaking with JailbreakMe 3.0, my iPhone got stuck at the recovery screen with iTunes logo and USB cable. Need help guys! Thanks.

Step 1: Download the latest version TinyUmbrella (Fix Recovery) for Windows (Direct Link) or Mac OS X (Direct Link).
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: Now, launch 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 device.
