Some people (including me) hate iOS 8. For me, it's the lag. My iPad 2 can't handle all of this new software and extra processes running in the background. Luckily, there is a way to downgrade from iOS 8 back to iOS 7.
Unfortunately you will lose all of your apps/media unless you made a backup of your iDevice while it was still on iOS 7.
Head over to
http://www.icj.me/ios/all and find your device and download the ios 7.1.2 .ipsw file listed next to it.
Remember. This will only work if the iOS version is highlighted in green (currently iOS 7.1.2 is!) because Apple is still signing it. AKA letting users "update" to that firmware version.
Then go onto iTunes on your computer and find your iPad listed there.
Hold down shift (command for macs) and click on the restore button (unfortunately clicking update to switch to a lower iOS version doesn't work)
A window will pop up and from there you can select the .ipsw that you downloaded earlier.
It should restore your iPad to the earlier iOS 7 and now you have successfully downgraded!
Good luck to you if you try this tutorial.
I will not be held responsible if anything goes wrong.
(make sure to back your iDevice up first just in case something doesn't work. But when you restore you'll
need to select an older back up that was made when your iDevice was on iOS 7.)
