Prerequisites to downgrade iOS 8.1.1:

Make sure you have updated your device to the latest iTunes. Download appropriate iOS firmware file for your device – direct download links below.

Connect your Apple device to your PC and wait for iTunes to open and connect to your device.
Click on the device button in iTunes and hold down the Alt / option key (Mac) or shift key (Windows) and click Check for Update button in the Summary pane.
From the download links shared below, download the appropriate file. Locate the same .ipsw file downloaded from links and select it.
In case you don’t see any new version to downgrade to:
- create a backup, and then put your device into DFU (Direct Firmware Update) mode. DFU will help you install whichever OS you want to.

Important: Apple doesn’t support downgrading to older firmware builds. This method will only work until Apple signs the iOS 8.1.1 firmware, which will likely happen very soon.
