I keep trying to install the 16.3 software update but it keeps showing an error at the end of the install.

Try updating using a computer.

Update your iPhone or iPad - Apple Support

What kind of error message? What does it say?

I was able to download from my PC but the restore failed. Ended up having to go to Apple Store to fix it.

i have the same problem. This is the message. Download all the update, got stuck at 0 second, paused and got this message.

Same error.

same issue here. Anyone use a computer and can confirm if it worked?

I've try using my MacBook Pro and it freezed 2 times and now my iPhone is stuck at 95% of the update and i can't do anything... not event restart it :(((((

I’m having a same issue with iPad 8th generation. I restarted my iPad but no success.
