iPhone 4 Battery Dies while Jailbreaking with Redsn0w 0.9.8b4

Hi guys, please help to get my iPhone 4 working again. I am trying to jailbreak my iPhone 4 on iOS 4.3.5 using Redsn0w but my battery dies in the middle of the jailbreak process. As we speak, the iPhone is stuck in recovery mode, with iTunes logo and USB. If anyone could help, I would greatly appreciate.  Thanks In advance.

Hell Ronnie, to fix this, you will need to kick your iPhone out of recovery mode and then restore it to stock iOS 4.3.5 and then re-jailbreak using Redsn0w 0.9.8b4. First, you will need to use TinyUmbrella (Fix Recovery) to kick your iPhone out of recovery mode loop. The steps on how to use TinyUmbrella (Fix Recovery) can be found 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 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.

After kicking your iPhone out of recovery mode, you should now restore it to stock iOS 4.3.5 through iTunes to ensure that you have a fresh firmware installed on your iPhone before jailbreaking it. You can check this blog post to download and know more about iOS 4.3.5. Then once completely restored on iOS 4.3.5, you can now jailbreak it using Redsn0w 0.9.8b4. This time, make sure that your battery is fully charged before jailbreaking it. You can refer on this tutorial on how to jailbreak using Redsn0w 0.9.8b4.
