New iPad interrupted during software update, now only shows HELLO screen

My bro is in medical rehab and I bought him a new iPad 10th generation to replace his old one with a smashed screen. It’s the first time he’s ever had a major medical problem, so I wanted to help him.

I used the Quick Start which I’ve done in the past with other devices. Then the new iPad said it needed to do a software update. I okayed it and then after about an hour it still showed the preparing (or installing, don’t remember..exhausted) and so I shut both machines off. The old one shut off but the new one tried to restart and I held the top button down till the Apple logo came on.

The “Hello” screen came on and when I swiped up, I could see the ghost of the passcode page, but it disappears behind the hello page every time.

Any ideas? Some places said connect to a computer, but the instructions are a little alarming to me, now that I’m retired and don’t use desktops anymore.

thanks!
