Uh...
I don't believe I was addressing you and other users here had very good experince and results with having Apple Store personnel resssurrect older iPad models that were either dead or fubared to the point that the user couldn't recover their iPads without Apple's help.
If your experience with your local Apple Store was different, contact Apple at 1-800-MYAPPLE, ask for customer service and calmy tell them about the poor service you received from your Apple Store location.
Older iPads are STILL supported on the current iOS, issues aside.
My iPad 2 and 3 models are performing great on the last iOS 9.2.1.
Apple has been having continung issues with the latest iOS 9.3 updates.
If you feel you got treated poorly at your local Apple Store, contact Apple at the phone number I have gven you and calmly explain how you felt you were treated with the Apple Genius employees about how they weren't able to help you with your iPad issues.
Good Luck!
