iPhone Stuck in Recovery Mode while Jailbreaking iOS 4.3.5 Using Redsn0w 0.9.9b1

Hi Jaxov, I am a new iPhone user and have just started to jailbreak my iPhone on iOS 4.3.5. I used Redsn0w 0.9.9b1 on Windows for this purpose. While jailbreaking, after putting my iPhone in DFU mode, I’ve accidentally bumped on my device and disconnected it from the computer. Now, the device is stuck in recovery mode. I already tried to put my iPhone in DFU mode but no luck. I really don’t have any idea how to fix this. Is my iPhone bricked? Please help. Thanks.

Hello Mauricio, your iPhone is not bricked, it’s just stuck in endless recovery mode loop. Anyway, the good news is you can easily kick your iPhone out of recovery mode using the standalone TinyUmbrella (Fix Recovery). The tutorial on how to use TinyUmbrella (Fix Recovery) is posted below:

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 to 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.

After fixing your iPhone, you can now rejailbreak it. But this time instead of using Redsn0w 0.9.9b1, I would recommend you to use Redsn0w 0.9.8b7 for iOS 4.3.5 tethered jailbreak. This is primarily because of the fact that Redsn0w 0.9.9b1 is quite laggy. Anyway, you can download the Windows version of Redsn0w 0.9.8b7 using this link (Mac OS X users can get Redsn0w 0.9.8b7 from here). Then you can refer on this tutorial on how to jailbreak iPhone 4 on iOS 4.3.5 using Redsn0w.
