I just bought/downloaded the air display app, used it, shut it off, and now the ipad won't shut off. It's not frozen - I can load apps. and I can't do a hard reset either ... !?!?!?!?
How did you try to reset iPadl? Did you hold the top and home buttons until the apple logo was showing? I've never seen a lockup on an iPad/iPod/iPhone that didn't respond to a reset.
It may be a rogue all, also. Try holding the top button until you see the slide to turn off, then hold the home button to quit an errant app.
Hi. I have the same problem but don't have air display app. I keep pressing the on/off button without result. No way to reset either. And I've tried to reinitialize everything, but without change. An idea anybody?
My iPad being still under guarantee, I brought it back to the shop. Guess what, Apple just changed it.... There's probably no way to solve this problem.
