Sn0wbreeze 2.7.1 Bricked iPhone 4 After Jailbreaking iOS 4.3.3

Hi, I have successfully jailbroken my iPhone 4  on iOS 4.3.3 yesterday using Sn0wbreeze 2.7.1 on my PC. However, after turning it off and charging its battery, the device got stuck! It just keeps on booting in recovery mode. Should I run Redsn0w and re-jailbreak my iPhone? Is my iPhone bricked? Thanks.

Asked by: Alvin from Lexington, Kentucky

Hello Alvin, do you rely on Ultrasn0w unlock? If not, then you should jailbreak your iPhone using either Redsn0w or JailbreakMe 3.0 as Sn0wbreeze is intended for iPhone users who want to preserve the unlockable baseband of their device. Anyway, your iPhone is not bricked and it should work again after kicking it out of infinite recovery mode loop. To do that, you can use the standalone TinyUmbrella (Fix Recovery) tool. If you aren’t familiar with the procedures, then you can refer on the tutorial posted below.

Step 1: Download the latest version TinyUmbrella (Fix Recovery) for Windows using this link (Mac OS X users can download TinyUmbrella Fix Recovery from here).

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 10.4.1 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.

Also, since you are still on iOS 4.3.3. I would recommend you to save the SHSH blobs of your device using iFaith SHSH Blobs Dumper so that you will be able to downgrade your iPhone back to iOS 4.3.3 if you have accidentally upgraded it to the latest iPhone firmware. The tutorial on how to save SHSH blobs using iFaith can be found here.
