Downgrading from iOS 6 to iOS 5.1.1 is possible for older A4 devices like the iPhone 4, iPhone 3GS, and iPod touch 4th generation, provided you have saved SHSH blobs for iOS 5.1.1. You must use a tool like RedSn0w to stitch your blobs into a custom IPSW firmware file and then restore your device using iTunes. For newer devices like the iPhone 4S or iPhone 5, downgrading is generally not possible because there is no bootrom exploit available for those models on these firmware versions. Ensure you have the correct IPSW for your specific model and the latest version of RedSn0w before you begin. You can find detailed step-by-step guides for each device in the iClarified tutorials section.

It is possible to downgrade as long as you have your SHSH blobs saved for iOS 5.1.1. You will need to download the latest version of RedSn0w and follow the specific tutorial for your device.
