This tutorial will help you downgrade your iOS device back from iOS 5 beta to iOS 4.3.3 or older. There might be several reasons for downgrading. Be it a bricked iOS device stuck at Apple logo or maybe you want to downgrade back because of the bugs in iOS 5 and lack of an untethered jailbreak. No matter what the reason be you will be able to go back to iOS 4.

We hope you have your SHSH blobs saved using TinyUmbrella but even if you haven’t you can still go back to iOS 4.3.3 at least since Apple is still signing that firmware and will continue to do so until iOS 5 is out of beta and released officially.

If you want to downgrade to a firmware older than iOS 4.3.3 like 4.3.2 or 4.3.1 then you need to have saved SHSH blobs previously. The procedure is same as what’s mentioned below except that you need to first launch TinyUmbrella and click on start TSS Server before following this tutorial.

Tools required to Downgrade iOS 5 beta to iOS 4.3.3:

You just need iTunes 10.3 or iTunes 10.5 beta installed on your computer and also the iOS 4.3.3 firmware file using the links below:

• Where to Download iPad Firmware From
• Where to Download iPhone Firmware from
• Where to Download iPod Touch IPSW Firmware from

How to Downgrade iOS 5.0b1 to iOS 4.3.3:

Connect your iPhone to the Mac and then place it in DFU mode. It’s pretty simple actually. Just press and hold the home and power button till the iPhone turns off and leave power button just before the apple logo is about to reappears. The iPhone screen will remain black but iTunes will detect it. In case you are facing difficulties use our guide to put iPhone into DFU mode.

iTunes will alert you that an iPhone is detected in recovery mode.

Now press alt/option on your Mac’s keyboard (Shift key for windows users) and then click on Restore. iTunes will ask you to browse for the firmware file. Point it to the file we downloaded a few steps earlier.

iTunes will ask for a confirmation to erase and restore your iOS device to iOS 4.3.3. Click on Restore to proceed.

In around five to ten minutes the restore process will be done and your iPhone will restart.

Please note that the result may not be the same for you. The iPhone used in this tutorial had a rebel sim and therefore did not get any error. If you get any iTunes error like 1013, 1015, 1604, 3002 etc. don’t panic. The firmware has been downgraded from iOS 5 beta already.

Now you just need to bring your iOS device out of recovery. Use RecBoot or TinyUmbrella to exit recovery. Exit iTunes and launch TinyUmbrella and then click on Exit Recovery.
