Important note: Since downgrading erases everything off a device therefore make a backup of everything using iCloud or iTunes. It's very important that you do so otherwise you will lose all your important files and data.
1. Download the firmware file to which you wish to downgrade back to.
2. Assuming you have backed up everything, connect your device to your PC or Mac using a Lightning cable.
3. Launch iTunes. Windows users can download it from here: apple.com/itunes
4. As soon as your device is detected, click on the little iPhone shaped icon on the top left hand corner of iTunes.
5. Now click on the Restore iPhone button while holding down the left Shift key (Windows) or the left Option key (Mac).
6. Select the firmware file you downloaded in step 1.
7. The firmware file will first be verified with Apple before it is restored onto your device. If you have selected a version of iOS that is currently not being signed by Apple then the entire process would simply fail and you have to start all over again. So please, be very careful before proceeding.
