My iPad updated and now the display is unresponsive

If you have been unable to resolve the problem with a forced-restart and/or factory restore, you would be best advised to seek assistance directly from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page.

Alternatively, you can initiate and manage your support cases from Apple devices using the excellent Apple Support App. If not already installed, the App can be downloaded from the App Store:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to offer assistance:

Found that my iPad pro m1 also had problems when starting it today after updating to 17.4 yesterday. Apple logo splash-screen showed up and disappeared, but after that completely dark. No reaction from tuch-screen or buttons. Plugged it in to charge to see if that could wake it up, but nothing. Then by pressing the top + volume buttons I got the shutdown screen to appear, so the device was apparently on but not showing the screen, and after cancelling this I could start to use the device again. Don’t know if this helps, but hope you manage to wake your device as well.

mine bricked showing zero charge (with a full battery and wouldn’t turn on until i repeatedly and quickly pressed the home button

give it a try it might work ¯\_()_/¯

Edit: seems I have to wake up the device with the shutdown sequence every time, as it does not respond to the buttons or touch if the screen has turned off

Edit 2: Changed some of the accessibility options (touch or attention related) back and forth and did a restart. Now the buttons and screen reacts normally again.

Im stuck on the restore on iTunes page and its so frustrating all because of the 17.4 software update
