How to Downgrade iOS 5 to iOS 4.3.3 on iPhone, iPad & iPod Touch
Few days before Apple announced iOS 5 at the WWDC 2011 with some features similar to Android, and later it was jailbroken on the iPod Touch by MuscleNerd. Some of you might have upgraded to iOS 5, but there had been a buzz going around on Twitter and different forums that iOS 5 lags on iPod Touch 4th Gen, and even some of the features are missing. On the other side it is working fine for some people. So if you are the one who is facing lag problem, you might want to downgrade it to iOS 4.3.3 or older firmware, or you could wait for the next Beta release of iOS 5.
Follow the steps below to downgrade iOS 5 to iOS 4.3.3. First make sure that you have latest version of iTunes installed.
1. Download iOS 4.3.3 from here.
2. Connect your device to your computer, make sure that its turned off.
3. Now you have to Press Home + Power Button for 10 seconds.
4. After 10 seconds, release the Power Button, but keep on holding the Home Button for next 25 seconds.
5. If you followed the above 2 steps correctly, your device will enter in DFU Mode. Now open iTunes. iTunes will detect your device and will alert you for the recovery mode. Press OK.
6. To downgrade to iOS 4.3.3, iTunes will ask for the IPSW file. Browse and select the firmware that you download at the start. Once you have selected the firmware, restoration procedure will begin.
7. Just sit back and relax. If you get an error or your device is stuck in recovery mode than you would have to download TinyUmbrella or RecBook. This will help your device to get out of recovery mode.
