First Gen iPad Pro gives error 9 and won't start
My first generation iPad Pro just stopped working. I have tried everything they said to do, holding down the home and start buttons for 10 seconds, using my new IMAC to force start it . I get an error 9, and followed the instructions on error 9 but my the screen remains black. I bought it in 2016. What do I do now?
