For Those who need to roll-back to iOS 8.0, you can follow the instructions below, Option 1 is Apple's method to do it, Option 2 is doing a Restore and Option 3 is a total wipe of the device. Here’s an important note (which Windows users should pay particular attention to; also, this is something that only applies if the user chooses to look for the desired IPSW file on the Internet). Your browser may change the IPSW file into a .zip file. For example, Microsoft’s Internet Explorer does this, if used to download the firmware bundle. This doesn’t mean it’s unusable. Instead of wasting time switching web browsers, just rename the file to end in “.ipsw” and iTunes will accept it.
Option 1: (Apple's way):
Follow these steps to reinstall iOS 8.0.
1. Make sure that you're using the latest version of iTunes.
2. Connect your iPhone to iTunes.
3. Back up your iPhone in iTunes on your Mac or PC. iCloud backups won't restore to earlier versions, including iOS 8.0.
