Black screen of death
I had my iPad plugged into my MacBook Air when I updated to Big Sur, now I have black screen of death on 2019 iPad. I have tried everything to get it to start. No battery charging icon when plugged into mains even after 1hr. Tried pressing home and on button for 30 secs and no apple logo, connected to laptop (cable into laptop first) and looked on finder but iPad not listed. I have absoubtley no idea what to do next
iPad, iPadOS 14
